Thread: 300 tdi cylinder head is off!!!

Take it to a head shop, after they fit new guides they will have to regrind the valve seats, I doubt you would have the equipment to do that.
If the head is shaved you will need to have the valve seats set a bit deeper to compensate for the head shave, Regards Frank.

Now I'm happy with the condition of the head overall.
No excess warpage
No cracks
No pitting
No corrosion

Exaust valves how ever have radial movement of 16 thou where 6 thou is the limit (only have imperial dial indicator). Valve stems measured ok. Now is this much of a concern? If so is the replacement of valve guides doable with a press without heating the head to 120 degrees as stated in the manual or is it machine shop job as a must? What sort of price are we talking then?

All cylinders have honing marks still visible. Is there anyglhing else I can check as far as pistons and rings without taking them out?

Thanx all!

Thanks Frank. I have access to a good press, that's why I was thinking of changing guides myself, but no valve regrinding tools except lapping paste and stick with suction cup. Head doesn't need macining as it is in good enough condition just valve guides.
