I'm abit lost.
Stripped down cam ladder and re-done the chain number of links. It's done by 18th and 19th link rather than the tool, which also fits in. It's an after market inlet cam shaft J revision correct part number. My engine is a bwa 2006 but for some reason come with an A revision intake?
It's got 182k miles on.
Worked fine before inlet cam replacement, apart from worn fuel pump lobe because it's a revision.
It runs poor on idle, and jumps between 35-48kw inlet angle, angle doesn't steady on idle. It's got what I think is a valve noise, which sounds like the normal tappet and goes away at 2-3k revs. I'm getting 115psi compression identical across all cylinders. The tappets noise did go away for 10minutes or so driving, then come back and has stayed.
It's got an after market exhaust cam pulley. After market chain and tensioner. Original oem exhaust cam that's got 180k miles on. This set up worked just fine. Now it's got an after market intake cam. could the tolerances be accumulated? Could the vvt solenoid be broken (reads 7ohms) or inactive? Could the hydraulic tappets with a new cam shaft be dry?
