Post subject:  Valve recession?

Does anyone know the values for valve recession on our 2.8 crd? I have my head at the machine shop to install new valves and they're asking for it. I tried googling it and also looked on the manual but didn't see anything.

Thanks,
Terry

Glad to read that you are replacing the exhaust valves, did not see this until after I posted about replacing them on your other thread on the glow plug problem!
as to the valve recession specs, this is the only number I could find:
Valve recession (service limit)
Exhaust & Intake 0.3 mm / 0.01181102 in
It was for a different 4 cylinder VM engine, but should still be close?

Thank you! Hopefully it's the same as our crd. I'll give the info to the machine shop to see if it makes sense to them.
