I believe I have noisy lifters on my 1991 Mercedes 300D 2.5 turbo.
I need to remove the cam.
I followed the FSM setting the engine to TDC. I used the cam marks, as the balancer is then showing chain wear. FSM says it’s designed to wear 2 degrees in the first 20k km.
I started to loosen the cam bolt. When I looked at the harmonic damper marks, they were way off, like almost 10 degrees. I held the sprocket in space by wedging it in place.
I’m concerned to turn the engine backwards. I have the chain tie wrapped to the gear so it can’t jump teeth.
This is how the FSM says to do it:
I didn’t that way with the shaft through the gear.
And the bolt removed:
I’m concerned about screwing up timing. I know I can always verify by looking at injection timing and turning the engine, but I don’t want to screw anything up.
Do I just turn the engine forwards/backwards the few degrees to get it back to where it was? Or what?
Thanks!
