Factory Oil Cooler on my 84??
 

After getting my 84 running great for the first time since I got it and enjoying and hour of cruising... I developed a massive oil leak. Towed it home. It looks like there is a line (2 of them) running from the radiator to the engine.. directly under the crank pulley that is spraying oil. Is this a factory oil cooler? Cant seem to find the part if it is. If not facory should I remove it? It was running soooooo good! even with the crossfire.... The vette is and 84 with auto trans... it was an homeless abused wreck that barely ran when I got it... Now it's become a well cared for baby. Any info on the oil cooler would be well appreciated.. thanks

Take the top off the radiator shroud and look in front of radiator

It sounds like one of the transmission lines blew a hole in it.

They run down the right side of the frame and the hole could be blowing out fluid towards the engine.

The only other line near the crank pulley is the one on the rack for the power steering, which is right in front of it.

Greg,

do you have pictures of this?

also, let us see a picture of your Vette/baby! :thumbs:

:iagree: 84's did not come with a factory oil cooler for the motors. As mentioned, you are referring to one of the transmission coolant lines running on the right side of the block. Maybe one of the rubber hoses which attach to the metal lines is leaking. Should be a relatively easy fix. Don't forget to check your tranny fluid. Good luck with the 84.

On another C4 site OP states;
"definately engine oil and not trans fluid."

IdaVette site
http://www.idavette.net/facts/84.htm
has 4295 '84 cars listed as having the KC4 oil cooler option

I also was of the belief that the only C4 oil cooler was the block mounted one until I was correctly on here recently by a '84 owner ( most likely CFI-EFI ).
Trying to find the thread; was about a '84 owner looking for replacement oil lines to cooler and everyone was telling him the lines were coolant lines

I bought my 84 new. I ordered the Z51 option and checked every option available. As far as I know, the oil cooler came out in 85 and I retrofitted my car. The oil cooler is the sandwich adapter above the oil filter and has no oil lines going to it, only coolant lines. I'm not sure what the KC4 option was but it wasn't available Feb 04.

you bought your 84 new??
wow you must be OLD.
around my age................:lol:

I found the option codes in the storage compartment... it does have the "optional" oil cooler.... lucky me..... and the hose is leaking... and so far no luck in finding a replacement hose... it almost looks like an a/c line with the fittings and all.... but its an oil cooler.... any idea where I might find one? THese things run so hot that it probably would not be a good idea to loose it altogether... any feedback on that idea?

I just wanna drive it and have fun with it....

Yea, we're the crusty ones. ;)

I do not know if you have oil cooler lines or not but here is an option if you need it. We replace our stock cooler lines on our trucks with hyd hose just about any shop that makes up hoses can do it for you and it is cheap.

:iagree:
Only place where you are going to get lines unless you make up some from s/s braided hose and AN fittings .Just take the old line in and they can make a exact replacement .25 years on I would replace both lines

Have you looked in front of radiator for cooler? You will have to access the cooler to remove line.
Take some pics while you are there to prove existence of Loch Ness cooler :thumbs:

Anyone know where I could go to or what kind of shop makes up these lines....I live on Long Island (NY).. posted a looking for just to see if anyone has some they'd like to sell.... cant believe it's still in the shop!!!

Thanks for the help
 

:cheers:Thanks for everyones help on the oil cooler lines. Ended up having to have them made...tried many chevy stores just in case someone had a dusty old pair sitting on a shelf. Here's an aftershoot. I get it back and it's running like crap. It ran great before the oil leak.. I figure the wires are soaked in oil (they were) I replace the left side being they were the ones that got soaked. I test drive the car.. still running bad. I have ut flatbedded to my buddys shop. The right side wires were burnt!!?? WTF? Now I know better than to replace half the wires... I guess just a coincedence... cost me anextra $100 for my dumbness. Another lesson learned.

But did you take any photos of the '84 oil cooler for the non believers :yesnod:

"They have Moses and the prophets, let [the non-believers] listen to them." Luke 16.29 ;)

My 84 also has this oil cooler I'm googling for replacement oil cooler lines and see this thread. So it looks I won't be able to find these lines and mine are leaking bad.
For you non believers these lines run from the oil filter block to the radiator down the left side of the engine. They are steel tube flare fittings to pipe threads on each end with a section of rubber coated braided steel in the middle very long versions of your power steering high pressure line. They have engine oil in them not coolant and not transmission fluid. I'm pretty sure I know a place to have them made here but to have to take them off and wait till there made is going to be a bummer it's my only car.

here are some factory oil cooler pictures on my 84 with a RPO code Kc4. Im foghting the issue of finding new lines or rubber hi temp hose for it.

Doug at Corvettes Unlimited on RT 109 in West Babylon , may have them

I realize this is a day late and a dollar short, but Moreland Hose in either Patchogue or Hempstead can crimp new hoses onto the ends for you.

Maybe it will help the next guy.
