Engine oil removal
Hello, Does anyone know if any of the various vacuum operated oil change thru the dipstick tube extraction systems will work with the C5 engine,? and do these systems get most all of the old oil out on a par with the normal gravity draining? Thanks for any hints and tips you may have.............

Not even close to as good a job. Not only is the C5 pan flat, but the dipstick tube comes into the pan towards the back. Couple that with the C5's natural rake (back higher than the front), and I wouldn't be surprised if you left a quart in the system.
Besides, how are you going to change the filter?

I use them all the time at work on a Mercedes Benz but they are designed to be drained from the top. The oil filter is on the top and the dipstick goes to the lowest part of the pan and it's only 1/8'' from the bottom. Thats why it works for them and why it won't work for you.

TRUE. But supose he's going to put his car up on a set of rhino ramps to remove his oil filter. Now the "rake" is front to back. Would he now be in a better position to drain his oil from up top ??

I personally wouldn't use one. Here's a recent thread on this subject that went around in C5 General: Hand Pump Oil Extractor

Using Rhino ramps, the proper technique would be to back the car up onto the ramps, then drain the engine. Unless the car is really slammed (which could cause the nose to drag) you should have enough clearance for a drain pan underneath.

well, i'll tell you, i've changed oil in C5's a dozen times, and i'm drawing a mental blank here, but i'm fairly sure the oil drain plug is at the front of the flat pan...
anyway, once, i tried the rhino ramp thing w/o jacking the rear of the car. after i drained the oil (apporx 20 minutes), i raised the rear slightly higher than the front, and got an additional 1/2 to 3/4 qt to drain. after allowing for a complete drain (again, approx 20 mins), and a new upf44 filter, both my (late) 2000 coupe and my (present) 04z06 both, take or took, 6.75 qts. i think by draining in a level position, one would get approx 6.5 qts out - by raising the rear slightly, you'll probably get an extra .25 qt. as far as those various vacuum operated oil change thru the dipstick tube extraction systems for removing the oil from the top, well THAT SUCKS!
i don't know about you, but i'm pretty **** - i want to get as much of the old oil out during an oil change as i can.

to get the remaining slug oil out of the bottom of the oil pan i do two things:
1. jack the rear up just slightly more then the front, that gets a bit but not much more.
2. run a full quart of oil though the motor. Pour a new bottle into the oil fill with the drain plug out. WHen you see clear oil come out the bottom you good to go. Takes about 1/3 to 3/4 qt to get the remaining slug out.
Let it drain for a good 30 min. Then put in the drain plug, put 3/4 qt or about that into the oil filter, put on oil filter, fill with oil.
So are you waisting an extra quart of oil?? I say no, it helps clean out the old oil.

Z06 Oil Change
I propose to drill and tap a hole on the rearmost lower section of the oilpan, so I can do my own oil changes without having to raise the car and tilt it forward. I'll simply drive up onto my ramps, and that angle will drain the oil wonderfully. In order to minimize shavings getting into the oil, I'll drop the pan before drilling and tapping, so I can clean out the shavings. Before anyone says" Why would you wanna do that", or "Are you nuts", I'll say that I wanna do that so I have more power when it comes to servicing my car. And yes, I AM nuts. There isn't a single car part that can't be modified to make it a better part. All's I'm doing is making it a better part. Lingenfelter, Saleen, and all those cats started this way. I'm next.

The absolutely safest way is to do it the old fashioned way. Jack up the car, butt higher than the nose. Let it drip for 30 minutes or maybe a couple of drinks timeline. Then you know you have all the old oil out of the bottom of the pan. I do that on all my cars, not just the vette.

For me, every oil change is an opportunity to crawl under the car and take a look for damage and picked up debris. I've found a CV joint cover with a small tear, once. Might've been a more costly repair if it went undetected for a long time.
If you have the agility and knees to get under the car once in a while, it's not a bad idea to do a little inspecting. No one will care about your car like you will.
