Hey guys I can hear a faint tapping noise coming from the top of the intake manifold/plenum.
Not sure if its the valve shims but tought it might be it
Where can I find shims are they removable or they are a bucket assembly? for these engine I looked everywhere but couldn't find any
Even looked for the whole bucket but no luck
New secondary chains and tensioners on boths sides, no cam lobe wear that I see. I always changed the oil and filter full syn mobil 1 5-30 each 8k.
Cylinder compression 180PSI on both banks, cleaned the fuel injectors.
Always ran 91octane.
No missfire
Thx
