i have a h22a4...my engine goes down every 300 miles....i saw oil coming out from the bottom of the engine...my friend told me maybe the balancer shaft seal broke. i had change the all head gaskets, but forget change the all the gaskets at the bottom. i want to know how many gasket below the head. thx thx for you help.

 

Hmmm... front and rear main seals, oil pan gasket, oil pump and gasket, balancer shaft oil seals, oil cooler and filter o-rings, oil lines...I think that's about it.

 

Might wanna check the cam seals just incase. I thought my balance shaft was leaking also but it proved to be my cam seals. I know that's not what you asked but just trying to help out.

 

thank you very much for your infos.
