My 91 300D has a tap at fast idle. It runs beautifully smooth and strong. When I bought it the PO said that a diesel shop said it may need a lifter. I don’t know that it’s true, but they are known to go bad on these engines after high mileage.
I pulled injectors for refurbishment, and needed to replace a glow plug and VC gasket, so now is the time to check them.
Engine looks clean and cam looks great. Not sure if the brown coloration in some of the photos is because of my brown garage roof, or something else.
So, what’s best practice for checking out lifters? My understanding for these is to turn the engine by hand until the cam is facing directly away from the lifter, and then use a plastic pressing tool of some sort (non-marking). If the lifters move, they’re bad and leaky… if they stay solid and firm then they’re good.
Is it as simple as that??
Thanks!
