Hey guys I have a big problem with my frount crank seal leaking. I have tryed wear sleeves and the lifter cover vent is fine I've also checked the crank for thrust it's a ok. I'm thinking of makeing vents on two of the vale covers like some of pullers I know do. Help would be taken to heart. THANKS GUYS

 

put a new seal on it whats the big problem? i just did mine last weekend and tabbed my kdp while i was there

 

I think he might mean that crankcase pressure is pushing oil past the seal...tboling, have you checked your crankcase vent tube for blockage...just read your post again, yes you did. That sort of blowby seems abnormal---is your timing cover somehow tweaked so that it doesn't align properly with the crank? My engine has 400k and I just had the timing cover off---the crank has no groove at all...did you get the speedie sleeve and seal as a matched set?

 

oh i c he didn't specify that so i was like why don't he just put another seal on. but that makes sense. You might wanna try taking the lid for the oil fill off and see if getting air into that way stops the leak cuz that way if it didn't work then most likely putting breathers on your valve covers wouldn't work either.
