Has anyone changed the oil in their LS6 at home? If so I'd be very interested to learn your technique since the LS6 engine has a flat-bottomed oil pan with the drain plug located at the front of the pan. This means jacking up the front of the car or putting it on Rhino ramps leaves the oil drain hole higher than the rear of the pan meaning the oil will not drain.

Does anyone have photos of the underside of the car showing safe jack points at the rear of the chassis? If I post photos of the underside can you identify the jack points?

Okay, here are some views of the rear underside:

Photo #3 right side


In the following you can make out what looks like red paint from the lift at the Chevy dealer. It is in the corresponding spot on the left side as well.

I appreciate the help.

actually the jacking points are on the side ....about 1 foot in front of rear wheel and 1 foot behind front.......there is a jacking puck that is bought or made to fit in the holes there...1/2 inch 1 1/2 inch oblong....i have seen many jack up the suspension by using a 2x4 across the rear subframe.....but you will have to drive up on some 2x6's to get a floor jack under there........i have a link somewhere for the 2x4 method somewhere ...if needed give a shout...........Dan 184

Okay, I'll go look at those spots. I'll photgraph them and post the photos.

The diagrams in the Owners Manual as well as the Shop Manual are simple line drawings which (to me anyway) are indeciperable. If you find that link for the jacking puck let me know and I'll get one. I've got several 2x4s as well as plywood that is needed to get the tires up to get the air dam past the Rhino ramp.

Thanks much!

hey bro i found the best link for a oil change......this site is very outdated but a few tips http://www.c5forum.com/diy/oilchange.php and yes that was me on the z site :partyon:
Okay, here is the photo from the site you referenced showing the jackstands in place under the rear end


and here is a closeup of the jackpoint you referred to on my car



I can see now why a plug of some sort (preferably urethane) would be required.

I'll search around on Eckler's site tonight and see if I can buy them. Thanks for the pointers, Dan, I appreciate it very much.:thumbsup:

BTW, your avatar is excellent. How did you shrink the photo without losing resolution?

One thing I discovered while doing my own oil change at about 700 miles , was that my oil drain plug was cross threaded into the oil pan at the mexican factory that assembles oil pans. With patience & perserverance & some jewellers files in my tool box, I managed to rectify the situation. When i was at the GM engine plant in St. Catherines last August, I pointed this out to them, & they couldn't care less. Good old GM product support. They obviously have never been to the Cadillac or lexus school of customer service. This is probably the only down side of owning a Corvette, GM doesn't care in my experience , anyway

I agree. That's why I prefer to do things such as oil changes myself. When you take your $51,000 car in for service and they don't seem to treat it any differently than a 1985 Chevy Cavalier (i.e., with indifference) it doesn't provide much incentive for a return visit.

Our Cadillac dealer on the other hand provides free oil changes, free car washes, and free Cappucino! And, they remember your name when you come back in. It's entirely possible that they are abusing us somehow, but at least they use K-Y Jelly.
