No need to skim but, you can see the corrosion damage around the edge of the coolant ways across the whole head.

The place on the left where its worse is actually between 2 water ways.

The most I might do is put a wipe of the green snot in that area (a technique used by Vx at the factory).

This is a pic of Mick Dundees which has had the coolant serviced very well on 100K + miles.



Note how much better the coolant ways are.

Just goes to show (yet again) the importance of proper servicing.

Was the area of failure the same as the area of dark grey?  If yes, then a very very light skim may suffice but remember the coolant bridge if the engine shop gets too keen. The head gasket is also designed to take up very minor imperfections by its very design...

Personally, if MDTM says dont skim then I wouldn't unless really neccessary....


Indeed, the major benefit of a composite gasket and why modern metal layer gaskets have a polymer coat to.

Markey - out of interest, why would you skim? No distortion or serious pitting etc - I guess after 150k miles, you won't be able to see your face in it?  :-/

just so its proper flat and were that dark patch is i wouldnt want to risk it will all the other work your doing james  :y

He has said that about at least 3 cars since I have known him, started with the GLS 2.0 trying to be an Elite, and then the STMO0123 2.5 CDX Facelift with LPG now owned by Phate123.

Mind you I did get 2 or 3 merged into one :)

Then there was the 2.0 LPG'd Estate, facelift 3.0 Elite, Range Rover, Peugeot and probably a few more... :D

Right when you have fixed everything on this car you can swap it for mine (plus 200euros negotiable) and then you need never buy another car! (and it has just had the cambelt changed).

Don't hang around though as the offer won't be there for ever.  :)

Taking a break - as interest faded a bit tonight.

Fitted all the inlet valves and seals in the 246 head - only to find a stem seal spring on the bench. So - had to strip them out again - and found a stem seal with a spring missing.

Ho hum - changed that seal - all done

2-4-6 head is rebuild, apart from the manifold - starting on 1-3-5 head tomorrow night.

Hope to have them ready to fit, at the weekend...

These stem seals, from autovaux - are black - is that OK? They usually are green, IME...
