Been reading up on this and wondering what is the problem as most 42's have a noisy valve train.
Why do these engines have a noisy valve train?.
where is the valve train wear accruing.
what to look for?.
what should be replaced.
cam, lifters, p-rods, rocker/shaft or valve top grind ?.
some one should be able to enlighten us all.

Not sure about a lot of that, but I know our rockers need regrinding.Quote:

EDIT:
Had to grind one because of the problem discussed here
TB42-Rocker-Assembly-help-needed.
I am planning to pull mine and have the rockers reground this July when i am off work. The rockers have had divits in them since I bought the Safari off an importer. They were never properly adjusted in Japan. Now to adjust them you have to tighten them a little bit closer than spec.
Let me know all of what happens, will you.Quote:
