Rover 200 engine swap

Not completely true.

Several things played a part in the headgaskets failing.

The main one is the position of the thermostat, which when it opened, would force cold coolant into the hot head which being alloy would make it contract quickly.

Add to this the plastic dowels used to keep the head in place. This meant that with the head expanding and contracting all the time, it rubbed away the sealant on the gasket, causing a failure.

Ah yes I forgot about the dowels. I think they cause as many problems as the gaskets. I've changed plenty of gaskets where all that's happened has a tiny piece of the rubber seal has come adrift and that was the cause of the problem in many cases.

Yes the liners normally are ok, saying that, ages ago we had a Rover where we changed the head and gasket and it still had the same problem, in the end it turned out to be a cracked liner.
I did change one a while ago also where the liners had eaten into the head. The head wasn't really worth using as it had already been skimmed before and we had another decent head in stock so we stuck that one on!

no there is all types of gaskets out and still do it eg multi layed steel,fibre gaskets etc they still suffer.

problem is they get very hot and when that happens the headgasket creates a ring where it sits and creates a deep groove so by the time its faced its going down to the softer ally hence why the head gasket can go straight after its been done.

we normally warn the customer of this.

A few years back my dad said he had a couple of headgaskets to change on a KV6 which were obviously the tin version. Not wanting to put the same back again he got in contacts with the a company that raced the KV6 and they said if you use the new (at the time) triple layer gasket then you'll have no more problems at all. They reckoned they ran those engines with the triple layers gaskets and ran more than standard power, and they said they just seem to be bullet proof. Reckoned that since they fitted the gaskets you just couldn't blow the enigne up (not that I think they really wanted to)!
So my dad purchased a couple of the new gaskets and the engines been fine to this day. :)

yeah liners can crack but rare.

its the head gasket that digs into the head not the liners there under the head gasket ;) .

Well yeah you know what I mean though. ;) :D
You say rare but I've heard of a reasonable amount, even the garage that was next to us said they had a fair few with that problem.

the kv6 is a v6 aint it? we dont get many of them in any way just the k16 and k8.

It is. Nearly all of the unsmashed Rovers I see up the breakers yard are in there because of headgasket though. I must've looked in the expansion bottle or oil cap of about 5 or 6 when I was up there once and all of them had the tell tale signs. :(

:p .

yeah we have had about 3 in the five years ive been there and seeing we do about 10 a week thats a low amount of liners compared to head gaskets but thats the ones we have been told about we dont do head removal etc we just do the machining for the garages and private customers
 
There is a mercedes benz in the background of one of the pictures, i am asking if he has any pictures as i am interested in mercedes cars :)
 
Well done on actually labelling some of the bits you're taking off mate :) Thats been our mistake on one of the engine swaps we did a while back. Luckily for us, the little connectors on most of the GTI engine were colour coded :)
 
Here ya go Jez
