Ok I have a huge problem.... I rebuilt my ls that I had just bought., put brand new gaskets, bearings and seals. After putting it in car, I developed small oil leak. After driving it for a day, that oil leak became a huge oild leak. After trouble shooting I narrowed it down to oil pump seal (crank seal). So I changed it along with oil pan gasket. Immediately after starting car back on, the other side of motor began to leak a lot. There was motor oil shooting from tranny case by flywheel. The only place you can leak from is the crank seal near flywheel. My question is, it wasn't leaking before, after fixing the other side, it immediately gave out on. Me. Could it be to much oil pressure? And what can be done about it?

 

Only if your pcv valve is shot and you valve cover breather is plugged, but even then smaller weaker gaskets would give way first. GSR's run much higher oil pressure than your LS could hope to achieve and they use the same seals. Maybe the seal is slipping out, or maybe it is leaking from your oil pan gasket (common leak in that area, and it is something you just messed with). did you use an OEM oil pan gasket?

 

Dude I posted for you on your other clone thread of this one... READ!!!

 

Ok thanks. And yea my pcv isn't hooked up and my breather is a breather filer. Should I hook that up to my intake instead? And if I fix oil pressure problem do I still have to replace crank seal?
