Was going to go with this one from Rovers North (not necessarily the 1 hole, but this brand... waiting to see condition of head and if it needs skimming before determining gasket thickness).

HEAD GASKET 200 & 300 TDI 1 HOLE 1.37mm, PLH704, LVB500200 - Rovers North - Classic Land Rover Parts

I can't tell if that's metal or composite. Anyone have experience with this one?

The head gasket thickness does not have anything to do with the head. The gasket thickness is set by the piston protrusion above the block so that the pistons do not hit the head.

I was under the impression I would need to go to a thicker gasket if I had the head skimmed as that would change the clearances. Thanks for clarifying -- I would have bought the wrong gasket.

Most people buy the 3 hole (largest) and don't worry about checking the protruding pistons.

I'd probably get the head skimmed, checked for flatness, check the valves guides for wear and replace the stem seals. Then put on a 3 hole and call it a day.

Checking protrusion is pretty easy to do, on the flip side

Would suggest fitting a set of hardned valve stem caps as well, they seem to disappear with time.these are the ones I have fitted before.

If you get a thicker gasket than required, you will have reduced compression. Not the best idea, IMO.

I wouldn't, unless there is wear. The original ones should last forever. It is only aftermarket ones that have problems.

IMO, only replace what is needed and make sure the new part is of known good quality. There are a lot of replacement engine parts that can not be trusted and replacing things that are fine leads to more problems.

I want to also say taking your head to a shop is a good idea. Add to the list checking the head for cracks.

When I replaced the head gasket on my 2.5NA a couple years ago, the shop found 2 cracks that I completely missed in my visual inspection. This surprised Carrie and I because the engine was running like a champ and we pulled the head only because of an oil leak in the corner of the head gasket.

If I had skipped the shop, I'm sure it would have run well as before, until the cracks propagated into the oil or coolant and left us stranded somewhere.

Always a good policy to have heads checked for flatness. Do one V8 head gasket job and skip that step and have it leak when you have it all put back together and you will never skip that step again.

Fixed!

This weekend was a big undertaking, but three days in the home shop and it's running incredibly well. I pulled the engine apart and had the head checked to see if it needed to be skimmed and checked for cracks. I cleaned everything, decarbonized, fresh gaskets and seals, valve adjustment, compression test, and reassembled. I took it for a 45-minute drive to celebrate 3 days of hard work and am blown away by the performance. The engine is running so well and sounds perfect. It's the 300Tdi I have been waiting for, for so many years. I'll be taking the 110 up into the mountains for some camping this weekend (will be above 10,000' for most of the weekend) and I'm looking forward to seeing how it performs loaded with gear and at high elevation. New rear windows and fresh wiring for the rear LEDs go into tomorrow and it's ready for some more adventures.

I opened the tent in the garage while I was working on it as motivation to get the job done. Can't take it camping if the engine doesn't run!

Awesome news! I love all the insight on these engines, to be found here. By the way how cold will it be at 10k feet?

Thanks! It's going to be cold at elevation. The first night will be around 10,500' and will certainly be well below freezing. The second night is going to be closer to 13,000' and might get down into the single digits. We're usually quite comfortable in the tent and the 110's heater is blowing strong, so we should be okay. It will be a good test of the entire setup - 4 adults and gear.

Are you going with others with other vehicles, just in case. Those elevations are no joke this time of the year when you haven't time to make sure the bugs have been addressed and double checked.

We're doing two smaller trips along the front range this week (9,000') to shake it down a little, but the weekend trip will have a backup vehicle with us.

Very cool. My wife is from the Silverton/Ouray area. Very jealous of your upcoming trips having spent some time in your beautiful region.

Ouray is out in an incredible part of the state! There never seems to be enough time in the week to get out and see everything Colorado has to offer. It's already November somehow... I don't know what happened to this year.
