I have a strange knocking issue with my 1jz. It is definitely a mechanical issue some where. It is very odd because i had this engine running in my other car before putting it in this one and had no problems what so ever. It has no relation to the engine rpms and is intermittent. I am thinking that perhaps a wheel on one of my turbo's is chipped and making this noise when they spool. Oil pressure is @ 40 psi. Has anybody had a similar problem? Can someone tell me if i'm going in the right direction as to leading to the turbos for the problem?
