just bought a new 99 corvette frc with some issues
hey guys, i just bought a beautiful 99 corvette frc 6 speed for $6000 cash a few days ago from one of my long lost classmates. he drove it for about a year and decided it wasn't for him maybe because of the issues?!?!
anyways it is in excellent condition inside and out. the price was just irresistable and i thought it was a really good deal. please tell me it was a good deal... please
LOL...
of course it is a very high mileage car originally bought in WA state with 249k miles. it has had 4 past owners according to carfax. it has never been in an accident, again according to carfax. but of course it has the issues a high mileage car would have.
the first issue is at start up. when it is started up and idling in the morning, you can hear some tapping. it seems kind of loud and would be most likely noticeable to a bystander. it goes away completely after it is fully warmed up. my mechanic friend told me that it could be valvetrain noise or possibly rod knock from an abusive former owner. so once the car is fully warmed up, all the noises vanish and the engine sounds smooth. so whats causing the noise when the motor is cold?
the second issue is clutch noise and some shifting problems. each time i push the clutch pedal in, i hear a loud whining noise that doesn't exactly sound normal. when i shift, sometimes 3rd, 4th, and 6th gears grind. 3rd and 4th gears seem really hard to get into and will grind when you force it. when i feather the clutch and not push it in all the way to shift, i find a sweet spot where it will seem to go into gear really easily, almost too easily. clutch seems to engage very harshly at times and will sometimes will engage normally. it makes me wonder what the hell this problem is...
the third issue is the belt noise with the AC. when you turn the AC on, you could hear it. it sounds like the same chirping noise my mom's 04 chrysler minivan has been making for the past 2 years. the belt, AC compresser, water pump and the tensioner all looked like they have been replaced by the former owner so i am confused to what is making this noise. other than that the AC blows nice and ice cold.
the fourth issue is interior noise. theres a persistent rattle somewhere in the dash to the right and it is beginning to remind me of my old Z28 that i sold a year ago. is this noise also a common problem with these corvettes as they are on the newer 98 and up camaros?
the fifth and final issue is the engine temperature. seems a bit concerning that it gets a little warm. the gauge goes past the 220 mark on the gauge by about 2 notches. then the fan turns on and it cools down to just under the 220 mark. when the AC is on (with all that belt noise), the needle will be at the 220 mark and will stay there for however long the engine is on. is this car supposed to run that hot without the AC???
other than that it seems that the car runs great and gets great fuel mileage for a v8. i got about 31 mpg on the highway cruising down from valdosta, ga from where i bought it. any help with the car is appreciated... thanks!

Well Julia,
- The tapping noise is a common problem and probably nothing to worry about (Piston Slap) which is common on these motors.
- Second issue (Clutch Noise) is probably a bad throw-out bearing and that is going to be expensive as the whole drive line needs to be removed to replace it.
-Third (Air Conditioning) could be belt or compressor problem, hard to tell without some diagnostic work.
- Forth (Rattle), sorry can't help with that one.
- Fifth (Temperature) What you see is normal. Could check for dirt and clean out radiator and condenser with a spray hose.

Seriously though, congrats on your purchase. Sure the mileage is high, but so what. These cars will run for a long time when properly maintained.
Best of success with it. If you can do you own wrenching, you will save a lot of money on your car. Perhaps you might put a post in the southeast section looking for a shop in the Tampa area. I know there are several good shops down there.

Likely a valve train issue. Take it to a shop that specializes in LS engines and they will be able to diagnose it for you.
the second issue is clutch noise and some shifting problems. each time i push the clutch pedal in, i hear a loud whining noise that doesn't exactly sound normal. when i shift, sometimes 3rd, 4th, and 6th gears grind. 3rd and 4th gears seem really hard to get into and will grind when you force it. when i feather the clutch and not push it in all the way to shift, i find a sweet spot where it will seem to go into gear really easily, almost too easily. clutch seems to engage very harshly at times and will sometimes will engage normally. it makes me wonder what the hell this problem is...
Likely the throw-out bearing/slave cylinder going bad. Not an expensive part, but because of how the drivetrain is put together, it can be a pretty big job.
the third issue is the belt noise with the AC. when you turn the AC on, you could hear it. it sounds like the same chirping noise my mom's 04 chrysler minivan has been making for the past 2 years. the belt, AC compresser, water pump and the tensioner all looked like they have been replaced by the former owner so i am confused to what is making this noise. other than that the AC blows nice and ice cold.

Good luck with this one... it will drive you crazy looking for it. Fortunately, it is not a hard job to pull the dash out, but that doesn't guarantee that you will find the rattle.
the fifth and final issue is the engine temperature. seems a bit concerning that it gets a little warm. the gauge goes past the 220 mark on the gauge by about 2 notches. then the fan turns on and it cools down to just under the 220 mark. when the AC is on (with all that belt noise), the needle will be at the 220 mark and will stay there for however long the engine is on. is this car supposed to run that hot without the AC???
Perhaps one of your fans is not turning on. Check the fuses. Also flush the system. There could be a blockage somewhere.
other than that it seems that the car runs great and gets great fuel mileage for a v8. i got about 31 mpg on the highway cruising down from valdosta, ga from where i bought it. any help with the car is appreciated... thanks!

At that mileage, the tapping is most likely the lifters worn out. I know because I had to replace mine on my '99 at 274K miles and they were done.
Do a shifter alignment and see if that helps with the trans otherwise the synchros are about done.
The noisey HVAC could be any number of things but it wasn't too long past my lifters, I had to replace the compressor as well. It too was worn out.
Lastly, clean out the condensor/radiator by blowing or water flushing outward from the inside to remove the tiny rocks that you'll find stuck in vanes.
Pull the codes and see if anything else appears there

so the c5 is definitely a deal, has a lower theft rate and is a hundred times better looking that the old dsms i was very into back in my early years of driving.

1. I agree with those miles the lifters are on the way out. Personally if you don't have the cash and the car drives ok I would keep driving it but if you have the cash find a lower mile motor to drop in.
2. I agree syncro's are probley on there way out. Lot's of M6's for sale for about $500-$800.00 on the forum. You could flush your clutch fluid to see if it will help
3. I agree if the tensionor is good A/C compressor issue most likely
4. It's not bad going into the dash might have to do a bunch of taping or have a friend press where it is coming from to find out what the deal is with it.
5. It is normal but I suggest do a thermosat swap and get the fans programmed to come on eariler.
Enjoy your FRC. Mine get's pleanty of attention

daymn, you had a ton of miles on your old car. thats more than most cars on the road today. thought i had you beat LOL. there are no codes thank the Lord... how do i do a shifter alignment? anyways the condenser and radiator are clean of any debris. they also look fairly new.

There are plenty of posts here on doing the shifter alignment... the quick and dirty here is access the shifter, put it in neutral. Push down the alignment pin which is in the front of the shifter, all the way down till its locked and the shifter won't move. Loosen the clamp torx screw on the shifter shaft and you will probably see it move. Re-righten the screw and put it back together. Drive it. If you still have the problems, then its synchro time and at that mileage, don't be surprised. Nothing lasts forever but if maintained, it will!

Drain and refill the trans with fresh ATF! You will be amazed at the improvement if the old fluid is old and nasty. (yes your six speed tranny uses ATF as the oil)
The AC Condenser and the radiator do a very good job of collecting and retaining DIRT and SAND. Use a strong stream of water and back flush the fins to wash out the dirt. Theres a 1" space between the two radiators. That space is usually pretty dirty and full of grass.

And don't use Mobil1 ATF just in case you got unlucky like I did and got a BorgWarner transmission. The Mobil1 is great stuff, but super bad for the BW trans.

Might as well throw my 2 cents in.
the first issue is at start up. when it is started up and idling in the morning, you can hear some tapping. it seems kind of loud and would be most likely noticeable to a bystander. it goes away completely after it is fully warmed up. my mechanic friend told me that it could be valvetrain noise or possibly rod knock from an abusive former owner. so once the car is fully warmed up, all the noises vanish and the engine sounds smooth. so whats causing the noise when the motor is cold?
Classic symptom of piston slap or perhaps a slightly collapsed skirt. Not really unusual for an engine with that many miles. Nothing to really worry about, just don't rev it too high when it's cold.
the second issue is clutch noise and some shifting problems. each time i push the clutch pedal in, i hear a loud whining noise that doesn't exactly sound normal. when i shift, sometimes 3rd, 4th, and 6th gears grind. 3rd and 4th gears seem really hard to get into and will grind when you force it. when i feather the clutch and not push it in all the way to shift, i find a sweet spot where it will seem to go into gear really easily, almost too easily. clutch seems to engage very harshly at times and will sometimes will engage normally. it makes me wonder what the hell this problem is...
Definitely the release bearing is making the noise. The shifting issues may the the synchos or if the release bearing is really really bad it may not be releasing the clutch completely. This condition will rip the syncros out of the transmission very quickly. It's likely the release bearing (need new clutch assembly) and synchos (try replacing the fluid, might help some otherwise look for another transmission or rebuild).
the third issue is the belt noise with the AC. when you turn the AC on, you could hear it. it sounds like the same chirping noise my mom's 04 chrysler minivan has been making for the past 2 years. the belt, AC compresser, water pump and the tensioner all looked like they have been replaced by the former owner so i am confused to what is making this noise. other than that the AC blows nice and ice cold.
Looks around, probably something simple. Sounds like the belt to me. Maybe belt alignment.
the fourth issue is interior noise. theres a persistent rattle somewhere in the dash to the right and it is beginning to remind me of my old Z28 that i sold a year ago. is this noise also a common problem with these corvettes as they are on the newer 98 and up camaros?
No idea on this one. Loose screw? I don't think this is common to C5s, first I heard of a rattle in this area.
the fifth and final issue is the engine temperature. seems a bit concerning that it gets a little warm. the gauge goes past the 220 mark on the gauge by about 2 notches. then the fan turns on and it cools down to just under the 220 mark. when the AC is on (with all that belt noise), the needle will be at the 220 mark and will stay there for however long the engine is on. is this car supposed to run that hot without the AC???
This is perfectly normal although maybe a little hot. Might want to flush the cooling system and check for debris in the radiator.

im fairly experienced wrenching, better than a lot of boys LOL and doing most work on my own. i did own lot of turbo dsms in the past and did everything from my own motor work, trans work to tuning (eagle talon, plymouth laser, mitsubishi eclipse) in the past so id hope that the c5 would be as user friendly to work on as dsms are to me. i hope i learn more about the c5s they are a very appealing car for the money. heck i bought my first turbo dsm in 1999 for $10000 cash and thought it was the best car ever until the day someone stole and stripped it clean. so the c5 is definitely a deal, has a lower theft rate and is a hundred times better looking that the old dsms i was very into back in my early years of driving.

UPDATE:
well it was my night off today so i just got finished replacing the atf in the trans. little to no improvement at all. i can still hear some noise. the clutch pedal is still iffy and i still have to feather it a little to find the sweet spot. my left leg is getting a little more exercise than i prefer. so i push the clutch too far in, it will grind gears when trying to shift quickly. too little, it will be hard to get into gear. when i push the clutch in just right, it goes into gear as smooth as butter. is there a clutch pedal adjustment procedure on these cars?
i was able to find the squeaking noise in the engine back and it definitely is the ac compresser. it just looks too new to have problems and my ac is cold so will machine oil around the ac clutch fix the squeaking problem or will it destroy the internal seals or clutch mechanism?
the dash rattle is still driving me nuts. ill have to play the music louder as a bandaid to this annoying problem. well a little forward pressure on the center of the dash with my hand stops the rattle but it will come back the moment i take my hand off it. what the hell! guess ill reserve that for another day.
dont wanna sound like a bitch or anything but im not looking for a relationship with anyone, anytime soon.

the dash rattle is still driving me nuts. ill have to play the music louder as a bandaid to this annoying problem. well a little forward pressure on the center of the dash with my hand stops the rattle but it will come back the moment i take my hand off it. what the hell! guess ill reserve that for another day.

With that many miles and the whirring with the clutch pedal in, I'd be pulling the drivetrain and taking a look at the clutch. Replace the throwout bearing, the pilot bushing, the slave cylinder and flush the fluid at the very least. An aftermarket extended bleeder line is a great investment if you're this far in at that point. The clutch may be toast too.
If your shifting problems persist, then you're probably gonna have to replace the tranny (probably just bad synchros if your clutch situation is squared away). You can get a really nice heavy-duty rebuild for <$2k, or just throw in a low mileage stocker for <$1k.
I have that same noise in my ~150k mile Silverado (5.3L). Piston slap or lifters, hard to tell. It's been there for a while, never gotten worse. I just don't move the truck for the first 30 seconds. I don't feel like doing the labor to replace the lifters when it might just be piston slap (harmless but annoying). So I live with it
Temps sound fine, they run "hot" on purpose from the factory. You can lower it with a lower t-stat and turning on the fans sooner, but it's fine either way. Cleaning the rad and such is a good idea regardless.
Try replacing the AC belt obviously. Check the tension(er), could be as simple as that. With the belt(s) removed, spin all the pulleys by hand and make sure one of them isn't hung up/crunchy/squeaky. Could just be a bad bearing in an idler pulley is all. Hard to say without doing what I just suggested.
