What is this oil change thing of which you speak ?????

talon90

None at all. The drain is at the bottom, back of the pan. I remember C5 owners going through great gyrations to make the car level to slightly higher in the rear to make sure all the oil drained out. I never had a problem. Once the drain and fill was complete it took 5.5 quarts to fill it back up.

Is there a crush washer to replace? That bit me on the wife's van--there was a slight drip when I tried to reuse the old washer. I want to make sure before I have the drain plug out and no oil in the engine.

What a spectacular looking subject auto . . .nicely done Brother Paul ! Many thanks- this will be helpful to many for years to come.

Perhaps you could prevail upon those with extraordinary access to put it in the FAQ sticky - memorialized forever?

talon90

No there is not a crush washer present, simply a conventional washer that I've just reused.

It's just that precision red clouding your judgment. Thanks for the kind words brother Rollie. Actually, Rich has all ready been kind enough to place it for all posterity as a link in the FAQ file under fluids and maintenance.

...there is so many of us that are indebted to you......geez, like others... I didn't realize how nice the ramp turnaround would make things for a person...

Paul -- Excellent write up and the pics are crystal clear which are invaluable (or as someone wise once said...a picture is worth a thousand words).

Thanks Paul! I too looked up the spec last night and sure enough 22 ft lbs is the spec. Next oil change I'll use a K&N filter and use a torque wrench to see how turn is needed to achieve the 22 ft lbs

Paul,
Nice write up. Your technique of flipping the ramp worked like a champ! I have a couple of suggestions:
1. Before removing the old filter, use a hammer and nail to tap a hole in the bottom of the filter to let the oil drain out. It's a lot less messy when removing the filter.
2. Pre-fill the new filter with oil before installing it.

I was changing my oil today and in preparation, I bought a box of 5W-30 Mobil 1 at Sam's Club. As I was draining the first bottle into the engine I noticed the bottle label said 10W-20. All six bottles were 5W-20 in a box labelled 5W-30! Sam's swapped out the rest of the box for a new box of 5W-30, which I checked before leaving the store.

Very detailed, good job!

One suggestion, one nit-pick. The nit-pick is that you need to bold step 15 label. The suggestion is that you warm the car up to about 100 degrees before the oil change to allow the oil, and contaminants, to flow out easier.

The Delco PF48 filters have a diagram of a hand turning the filter 3/4 turn and the Delco PF47 filters similarly show 3/4 - 1 turn. I agree with using the 3/4 turns as a consensus. All that your needing to do is insure the rubber gasket has enough compression to contain the oil pressure at the mating surface and anywhere in that range should do the trick.

Nice work on the PDF.

I have to disagree with this some of this oil change procedure.
You should jack the vette up so that it is almost level. The oil plug is mid way on the side of the pan, the rear should be slightly higher than the front for complete drainage.
I have been following Hib Halversons method since 1999. I believe it is also documented in the manual to have the car level.

The above link is for the C5 but should still apply.

I drive up on ramps, then jack the rear up according to the procedures listed. I then insert another set of ramps under the rear wheels to keep things safe and level.

I'm not taking anything away from Paul here... Just pointing out that the vette has a mid side plug and a baffled pan and needs a slightly different procedure.

Wasn't this oil change for a c6? Is there a difference between the oil draining characteristics between a c5 and c6?

talon90

I appreciate the comments. I too try to pay close attention to Mr. Halverson as I respect him tremendously as a technical resource. I too (as I mentioned in a previous post in this thread) used to raise the C5 to slightly above rear level to change the oil. I have been told that it wasn't necessary even in the C5 nor is it necessary in the C6. In my mind I have satisfied that curiosity for myself and believe that it isn't necessary in the C6. It may help draining "all" the oil out though I'm not convinced that it will. It may also aide in draining the oil out faster. My C6 has an oil capacity of 5.5 quarts. Using this procedure twice, I've drained 5.5 quarts and filled 5.5 quarts. With that in mind I am fine with the fact that I am not leaving any significant quantity of old oil behind when I perform an oil change.

I offered this DIY as an alternative and an instructional piece for those not familiar with the C6 and the oil change along with those that have limited tools and equipment at their disposal. It is far from gospel, it is far from the only way to perform an oil change on the Corvette and anyone could and should modify it to suit their abilities and resources.
