Pan R&R LQ9 6.0 Info please

**ronb03** · 12-11-2007, 03:35 PM

Hello, New to the forum and would like some advice. I just bought a 2004 LQ9 6.0 to replace the LT1 in a 79 Malibu. LQ9 has only 48,000 miles on it but the filter was nearly plugged up with a wax type substance. If you put it on your finger it is still very smooth and spreads with no abrasive in it. I would like to pull the pan and clean it and any oil lines but have never worked on an LS engine and am somewhat intimidated.
Would anyone like to advise me on this small project? Like what to be careful to do or not do, new gasket, reusing bolts that type of thing?

Thanking you in advance! ronb03

The oil pan gasket is riveted to the oil pan. Undo the bolts and it comes right off. The service manual says to drill out the rivets to replace the gasket. Put silicone on the front and rear covers where they meet the block and tighten the bolts: oil pan to front cover and the pan to block bolts 18 ft. lbs. and the oil pan to rear cover 106 in. lbs.
