I bought my head gasket ready for this weekend’s work, and got a two hole instead of a one hole gasket.

I wasn’t sure what size I needed at the counter (pressure of being under-informed at the parts shop!) so I went for ‘one higher’ than the one that came off.

Doing my duty and reading the manual again today I see that 2 hole and 3 hole are actually thinner?!

so dumb question can I save this gasket (very out of the packet and unreturnable) by using two hole over a one hole?

could I increase compression? :) or wreck my engine :(

Not sure what you are saying? If you are suggesting using two gaskets, one on top of the other, Don't.

You will be fine so long as you use one thicker than needed gasket. If you use a thinner one, you will cause damage.
 
Aha, I may be stupid

Thicker gaskets for greater piston protrusion. Am I reading this correctly? One hole (as removed) is the medium thickness and the 2 hole appears to be for minimum piston protrusion?

therefore a three hole or one hole should be okay but the two hole might be too thin?

thank you chaps!

Then if that is the case and the haynes is correct, I cannot see it written in the rave file for the td5.All it says is replace like for like.

the 2 hole is thinner and that surely is not a good thing.

Cheers

sadly I reckon you are right - it’s the sensible option to get a like-for-like gasket.

bugger, thought I might get it running today!

you either measure piston protrusion and check valve stand down or fit the same as came off 2 is apparently the thinnest and if it wasnt thick enough would cause pistons to hit the valves

moving the valve stem seems slightly out of my wheelhouse. I’ve got some feeler gauges somewhere but I think I’m going to go for a thicker gasket.
