Ok guys so finally i got a good motor....

I got a ls6 shortblock it was in good running condition....

I put in a new oil pump thats off the LSA motor Cts-v...

Car started up ran fine except my oil press is at 60 COLD and over 80 at WOT...

After a few runs the rear main was leaking baddd almost pissin

I had put in 10-40 wt oil just to flush the motor ... So i am like ok fine its the heavy oil ... dumped it and put 5-30 Edge ... Same problem....


As of now there are not oil coolers or anything...

Does anyone have a idea ... i am lost..... My next thing is putting in a oil cooler i got... but if that does not do it then idk..

I think the oil press has something to do with the rear main leak ?


Thanks guys

did you put the oil pan on first, then the rear cover? . . . might be miss aligned.
Put a little RTV in the bottom corners of the cover too.

Wow, I only wish to have good oil pressure, I'm with Tootall check out the alignments and fit then RTV it.

I am gussing its from too much oil press ... what do you guys think ?

You could probably do something like this. Im not sure the oil pressure would cause a rear main leak, the oil in the pan isnt under any pressure I think

your oil pressure sounds normal to me...
