I just got fully built botton end, Pistons,rods,bearing, fp red, gsc cams. etc... block was machined balanced with the flywheel.

On regular street tune no issues

As soon as it goes on the Dyno ( Dynapack) for full boost runs., oil begins to leak from between the Transmisson and transfer case. We replace both the o-ring twice small and large, and they weren't kinked... this is the 3rd time now, same problem..

some say vaccum lines ( catch can ) ? before the build ( 399 whp ) now looking at
500 whp, Ive been told because of gain horsepower a sudden pressure build up on the Transmission would vent from there ( but Shep built my tranny ) and they say can't be that..

so ???? anyone out there can help...

Thanks

 

anyone ???
