The valve noise of my '85 300D turbo appears to be excessive. I pulled the valve cover and checked the valve clearances but they were within spec. I did measure in the correct area. Maybe the amount of noise is normal? There is some "ticking" that is constant with the amount of revs the engine is making. Less revs less ticking, more revs more ticking.
It seems to be more noticeable than when I bought the car last Spring. The oil pressure is normal and I change the oil every 3000 miles using a diesel grade oil just as the previous owners had.
I know no of you will be able to hear it but how much valve noise is normal?
