Just to let people know, I have a B16a OBD0 PR3 engine.
I replaced my pan gasket because I proved that it was leaking, and after examining the gasket during the replacement process, I could see splits in the gasket. My new gasket is a Felpro gasket that is a blue colored rubbery gasket material. It leaks just a little bit, but it is sooooo annoying. I crawled under it and tightened down on it some more and I think it helped. When I installed the gasket, I used brake parts cleaner to clean the oil pan surface and to clean the oil pan railing of the block to make sure that there was no oil present on either of the two surfaces. I didn't use any silicone or sealant since the gasket is a rubbery type. At first, I torqued the gasket to the OEM recommended 108 inch pounds. Then again, after I found the leak, I tightened down on it some more (actually I tightened the hell out of it). I think that it might be an ultra slow leak. I may have just fixed it and not know it.
Two questions I would like to ask are:
1) Should I have tightened the hell out of the pan bolts from the start, or has anyone had any experience with this type of pan gasket?
2) Could I be having a problem with not venting enough crankcase pressure? I took the oil fill cap off and there was a shit load of crankcase pressure emitting through the fill hole (which is somewhat normal), but this pressure flow pretty much slowed to a halt when I increased the throttle. Should I say f##k the OEM ventilation system, and just run a reinforced clear vacuum hose from the valvecover fitting to a crankcase breather can with a filter on the top and a drain that goes to the oil pan or just have a drain valve that I empty periodically? I know on SB chevy's, you risk having a front/rear main seal leak when you do not ventilate the crankcase properly.
What do ya'll think???????????
