Hi guys, so from a previous post I have a lifter that is tapping pretty well and at the advice of multiple forum members I switched from Mobil 1 to Lubro Moly engine oil. The end result is that it did quiet down a bit but the lifter noise is still present, the noise appears to go and come at variable times or more accurately is less pronounced.

I still find it annoying as my CDI now sounds like an older 300D. With 199,500 miles I guess that I can’t complain but I want the engine to sound silky like it did when I first purchased the car.

Anything else that I can try?

Has anyone here ever replaced the lifters on a CDI themselves?... Is it very difficult?

Thank you guys in advance
