Engine noise
Nice to meet you. I have a 05 twin cam. I got a noise from the rockerhead, so I replaced the rocker arm, the push rod, and the lifter all. Still, the noise. It's fine during idling, but it happens when the rpm goes up or down. Is the crankshaft or flywheel bearing a problem?

The lifter, push rod, and rocker arm have all been replaced with new OEM products. Nevertheless, the noise continues.

I have replaced both the cam chain tensioner and cam bearing, the noise is from the left side of the engine, not the cam side.

Then your primary chain is too tight.. As light as the rattle is, I'd suspect you got rocker shaft rattle... BTW, I would not use new OEM lifters (99C) , they have been known to fail.
