Leaking oil out the top of the motor ea81


Recommended Posts

I have nearly fixed all my oil leaks and now it just refuses to stop leaking oil. Well nothing serious but there is oil where the 2 halves of the block meet at the top, I am sure its not the oil filler tube as i got it fixed on the 2nd attempt. I got a holey 180 also.

 

Anyone had any issues like this? Could this be from blowby, now there is no dodgy gasket for the pressure to escape from so it goes out the next best thing?

Are you using a geniune Subaru PCV valve? And have you replaced (REPLACED - not cleaned) the PCV filter in the airbox (assuming you still have it..)?

 

GD

 

Duno if the P.O. changed to a non standard valve, I have just cleaned it a couple of times in kero.

 

I dont Run that filter anymore since the holley 180 was installed.

 

 

 

 

Did subaru put a bead of rtv silicon between the to halves when they assyembled it?

I had a look today while it was idleing and you can see air bulbles coming up thru the seem.

 

Would blow-by be causing pressure in the crankcase?

Cause i dont see how the pressure inside the block could get higher than outside with just a dodgy pcv valve to be at fault.

 

Atm One valve cover goes to the air cleaner and the other runs to the pcv valve. Should I put back in the stock T piece with the restricted line going to aircleaner, imbertween head and pcv valve?

 

Would it be a bad idea to disconect the pcv hoes while running and see if the bubling stops?
