mike0chek Posted August 4, 2012 Report Share Posted August 4, 2012 so i did a leakdown on my motor today and it doesnt want to hold 6 psi, from 4 psi to 3 psi it took 9 mins to drop, is this acceptable?? the only leak is from one of the crank seals (between the crankshaft and the inner part of the seal) would you guys run this or should i split the cases again??

Its probably just leaking slightly around the drive gear on the clutch side,,,they all leak slightly around the key slot . You can seal it during assembly with Permatex ultra-black and it will take care of the issue. Quote Link to comment Share on other sites More sharing options...
