freshly build 2.3 stroker motore and build head, its keep pushing oil out of rear main seal
, dont know why plz help. already replace the seal twice. thank u

 

Need more info. What crank, who put the engine together?

 

debris, deep scratch on crank or the crank has been milled excessively. a big one would be not using a lube when installing

 

i hate when people say they need more info. i threw some good ideas out about what might be causing his issue. stop being a dick, give him some info and who cares if i or buschur put the motor together.

 

I did a Chevy 6 cyl. rebuild and the rear main leaked oil too. took it out and it had a odd bump in it from manufacturer. ^could also be all the above stated.

 

thanks guys am gonna address these issues to the guy who build the motor. if u come up some more reason or wht else could cause that plz help. thank u

 

Dude, just asking if it's a OEM crank or aftermarket. Used or not.
I'm not trying to be a d*ck.
Also, it does depend on who put it together. I just had a guy put one together himself and it only lasted 300 miles. So yes, a shop or a self build?

 

is it leaking where the seal meets the crank or where the seal rides on the adapter?

 

its manleys knife edge crank or u can also call it k1 manley

 

its a shop build, he is trying to work on it but i figured i can get some help from u guys and tell him wht could be the problem

 

gl man. at least this shop is helping you with it unlike some shops where they just say it didn't leak when it left.

 

i would think oem or after market they would be the same at the at the seal ends unless its faulty. what caused your rebuild to fail?

 

Depending on what rear main seal used, the spring inside the seal(behind the lip) can be twisted together to make it tighter. Just one or two turns might even work. Then put the spring back into the seal. Worst case is the spring, if it came with one popped out and is no longer giving tension to the sealing surface.
I'll go home and see if the oem have this spring or if it's only aftermarkets.

Good Luck in the meantime.

 

if needed i have a seal and the mounting plate

 

car never left the shop. when we first try to up the problem began. for some reason y i had a clue something like that would happen thats y when i hand him the car i told him give it back to me when its real brake the motor in ur self and all, i want the car when i drive it to trace and race so til then keep and do wht u have to do.
