Headgasket querie :mad: - Page 2

It doesn't feel as smooth as most cars, if you watch the rev counter on tick over you can see it fluctuate.

According to info on the Moto-Build web site the Land Rover gasket is suitable for all K Series from 1.4 up including VVC and Turbo.

I had the LR gasket & rail fitted to my 1.8 in March, about 12k miles ago, and the coolant level hasn't moved since.

SWORKS,
Apologies for repeating myself here from post#10, but why do you say omit the shim if you have not skimmed the head? The fitting instructions I have for the Landrover MLS states to use two parts of the gasket including the shim. I fitted the same Landrover MLS gasket to my non skimmed 214is head some 10k miles ago and it is still going strong. I didn't change the bolts or the oil rail, that would have doubled the value of the car if I had done that.
I have replaced another two friends K series engines with the MLS gasket, would like to know if I am doing it incorrectly by using all the parts in the kit.

Does the supplied kit from landrover come with instructions? This shim, what is it made from? I've not seen one before, I'm assuming it is a flat piece of alloy or soething similar, if that were the case, how does it seal? Surely you'd have to have a headgasket on both sides of the shim? I imagine I am being incredibly thick here so appologies in advance.

The Landrover kit comes with instructions to a degree, it does however tell you how to and where to fit the shim too. The shim is a black in colour alloy material and with a sticky/tacky substance coating on one side of it. The instructions include a diagram of where it should go in the sandwich.
The main body of the headgasket is made up of a sandwich too, so not really different from the shim really.
The instructions refer to a Landrover service bulletin, which is more detailed I would expect. I have not seen this one, unless anyone has a copy to spare, it would be a good reference document for all on here.

Cheers Lovel I agree. Is there a bulletin number? It may show up on a google search.

Sorry i didnt reply sooner - in my opinion the added shim with the new gasget is a lot thicker than the standard gasket, therefore must have an effect on the compression ratio. I had this arguement with one of my work colleagues who went on to fit the shim to a car that had not had the head skimmed. There was lots of swearing when he struggled to get the 2x 8mm bolts that go through the plastic cover into the head to line up (behind the cam pulleys)

This is the intruction that comes with the Landrover kit.

Very interesting, as a comparison, if I can recall correctly the all alloy Rover (Buick based) V8 engine fitted to the SD1 and the Landrovers differed in compression ratio between models, so the kit with the shim may in essence give the engine a longer stroke making for more low down torque. However the shim is so thin the change in comprression ratio would hardly be noticible at all to most folks.
To get to the bottom of this puzzle we would have to establish if the Freelander has the same compression ratio as the Rover engines

By the way the gasket also fits the 1.1 too.

I agree that the shim is thin but the head gasket looks thicker than the standard rover item so the two items combined together would make a difference to the cr. I didn't fit the shim to my 400 and i have also done head gaskets on approx 10 other cars and not used the shim, but it does say to use it in the instructions. my OPINION only :lol:
