Excessive wear of the valve guides is very common on M103 engines!
If that engine is burning oil then valve guide seals on a worn-out guide is like a band-aid on a cut that needs stitches.

A good machine shop can check for wear on those guides & replace them and you will have a better engine.

OK MB DOC, thanks for that explanation. I'll do the measurments myself, I'm in class for that already and have access to the valve guide removal tool, and get a new set.

I was just curious if these were a common wear item at my mileage, about 160K, which it seems they are.

Do you have any recomendations when I remove the valve gear, such as rotating the cam lobes down when I remove the rocker arms?

Thanks for the comments and recomendations.

BTW, I now have the intake manifold off and I'll be replacing the injector holders and seals, the idle bypass hoses. Do you have any other recomendations?
