Simple question: Can the 200Tdi cylinder head be skimmed ? According to the service manual it can't, according to my engine re-bore man, it can. Who is right !
Thanks

boogered if I know.
is it suspected to have been cooked, or is it just old?

Boogered if I know either - I put the thing on a surface plate at work, and I couldn't see any warping, but I am still at a loss to explain what popped the middle two pistons on the engine I am rebuilding...No signs of blown gasket AFAIK, no marks on the head.
Mis-clamped when reassembled ?
Anyhow -its BEEN reskimmed, so I'm knackered now, if there is a problem with having it done.

We've had several done with no comment from the engine place, including mine (well, more of a severe polish really on mine).

IME yes but.... there's a slight possibility of valves and pistons meeting after a skim. You can overcome this by re-cutting the valve seats to move the valves back into the head by the same amount you skim off it.

Bit late but rest assured it will be fine. I have had loads done with no problems.

I suspect there are graded gaskets, if so, fit the fattest one.

Austin Hi,
AFAIK there are three different types of head gaskets and their difference is their thickness. The easy way to check what is what is by looking at how many holes there are in the visible part of the head gasket when fitted on the engine. One hole is the thinner, two holes is the medium thickness (and usually fitted on the engines when they leave the factory) and three holes for the thicker variant. I guess it would be prudent to fit the thicker type when skimming the head.
Have not done it but it sounds logical.
Take care Pantelis
