Oil Leaks I had an engine built about 5000 miles ago.
LT1 383 4 bolt
10.5 comp ratio
Forged everything
Heads with 2.02 and 1.60 valves
Roller rockers
Custom cam etc etc.
Doug Rippie did the computer programming
Runs and idles great.
Goes very well and I use it for track days only.
But ! it leaks oil !
From the beginning this motor has leaked from the timing chain cover and then the rear oil pan. I just had the pan gasket replaced with new front/rear seals when I put a Spec 3 clutch in. It still leaks. Any one think maybe the stroker is causing this to happen ? and does anyone have any experience with different oil pans with more capacity.
I would appreciate any help/comments.
TIA.

Re: Oil Leaks It has to be either the seals/gaskets are damaged/not installed correctly or the block surface (that the seals/gaskets) sit against are damaged. If everything was "right", it wouldn't leak. 
Re: Oil Leaks I don't know, but I have the same problem! It's the '93 LT1 in my wife's car, but not a stroker. I re-sealed everything also, but with no luck. Quite a bit out the timing cover/oil pan interface, and some out the rear. My LS1 doesn't leak a drop!

Re: Oil Leaks It seems the LT1 is more prone to leaks than the LS1 ..however the LT1 has been around longer and therefore has "more miles" on the whole fleet. My question was ..is the 383 stroker more prone to leaking ? is there something that should be done when building it or that can be done now to prevent this ? Is the mass of the parts that are rotating in the block causing any physical change that increases the potential to leak.
This is my second new oil pan gasket ..installed by a very competant mechanic ..not me BTW.
Thanks again.
