Whats this look like to you guys? How hard is it to replace the pan gasket with the motor in the car? LS1 Transam

Thanks

 

Are you jacking up the car by the oil pan? Also, check for cracks around the bolt holes.

 

Naw he is just holding the motor up with the jack you can see the jack stands just to the left of the exhaust on the drivers side.

 

Have you done a cam or anything to your car? Mine looked similar when I had my tranny out, but not quite as bad. If you have dropped the oil pan, I bet you need to put some RTV on the front and back of the pan where it meets the front/rear cover. To replace the oil pan gasket the pan has to come out as it is riveted to the pan from the factory. To get the pan out you would need to drop the k-member some and/or raise up the engine with the mounts off.

 

Look at the top of the pan where the inside indented rectangle is. It looks like there could be a couple of cracks.

 

mine leaks pretty bad at the rear,mainly on the pass side.happened after i did my H/C.i'm hoping to fix it with some rtv at the corners where the pan and rear cover meet.like bowtieman said,you have to drop the k-member and support the motor somehow.

 

Are your pan bolts loose? If so, try retoquing them to 12 pounds feet or so. It isn't real critical as long as the gasket is evenly compressed. You could use a 3/8 inch rachet and snug them up with one hand. This is true on all the fasteners except the rear two which go into the rear cover which are torqued to 106 pound inches. Take a 1/4 inch drive rachet and just sung these up with one hand because 106 pound inches is barely over 8 foot pounds if you don't have a pound inch torque wrench. Go carefully. I believe the book value is 18 pounds feet from memory, but your gasket isn't new and you don't want to squish the rubber too flat and further prevent sealing. I've lowered the pan on my truck, to change the timing set and port the oil pump, but I've not removed the pan.

Also, look elsewhere besides the pan. Try to find the origin of the leak. Bowtieman81's idea on the RTV is a good one too.

The RTV comment I made came right from my GM service manual. The mating surfaces between the covers/pan won't be perfect, hence the RTV needed for a good seal.
