300tdi head gasket question

I've been looking around on the web for a while now and cant seem to understand where to locate the 1, 2, or 3, holes which represent the head gasket thickness. Anyone tell me how to find this so I can order the right head gasket and not all three... lol. I have the understanding that stripping the head and measuring is the best but this is my daily driver so I do not have the luxury of doing so.


Thanks in advance!

I always have the head skimmed so it is COMPLETELY flat, then would order the thickest possible from RDS.

I will be replacing head with the turner engineering performance one, figure I might as well upgrade. So if I have a new head I can fit the 0 (zero) hole one as it is the thickest??

thanks for the response!

That is what I commonly do.
Does Turned not supply the gasket set???

I think they do, but I was unsure of which thickness. Also, will be doing the water pump at the same time so I was ordering everything separately like a dummy.

The gasket thickness ain't like oversized pistons. It is not a question of new head or skimmed one. It is the measurement of the piston's head going out of the block. Well, at least that is my understanding of it. Having the thickess gasket is a safe bet but, will it last as long as the proper one for your engine will?

Indicator is located just below and slightly back from the #3 glow plug opening - if not changing anything in the bottom-end you can use the same gasket size you are replacing (or measure for piston extension above the block and size appropriately)

The location is a little bit hidden by the airfilter bracket.

You'll see the head gasket tab exposed where stated.

The gasket will have 1,2 or 3 small holes existing. Turner's should supply the Elring make of gasket.

If it were I,I'd replace with what has been on it already. E.g. my 300tdi came out of the factory with a 3 hole gasket.

All the best

There is a red circle where you will find the holes. This one appears to be a two hole.

Thanks for the replies guys, sorry for the slow response... somehow I got pneumonia and have been sick as a dog so hadn't messed with defender. Last of the parts should be coming in this week and I'll be getting to work.
