Thats paraffin....both heads stood for 24 hours with the combustion bowls filled with the stuff.

Anything will do though, as long as its quite thin and searching plus doesn't evaporate to quickly!

6 years 73k no codes....   Yet..... :-X

My light first came on at about 48-50K at a guess. I'll give it the benefit of the doubt and say that it was constantly on by 60K, now on 80K and still on.

Never seen signs of stem seal trouble though. Oil consumption is zero, inlet valve stems are certainly clean and dry (although they will be regularly washed with petrol so not a reliable indicator). Haven't noticed any smoke at startup but will keep an eye out...

Kevin

I had similar issues with a 4 pot veccy some years ago.  Turned out to be the same valve stem oil seals.  One had a great big hole in it which caused smoky start-ups, a blip while cruising on motorways, and borderline MOT emission passes.  Whipped the heads off changed out reground valve seats and rebuilt all in a weekend.

I might crack the welder out tonight and the 1 inch drill (sadly the O2 boses are imperial sizes) and weld the new O2 sensor mounts into the cat sections.

Probably  :y ...... I just happen to know for the Ford cos I made a 'special tool' to do them after my Dad still had the valve stem seals for one head on a shelf at the back of his garage when he'd finished re-building his engine.  :-?  ;D  ;D  ;D

On with its head (s)!!!
« Reply #193 on: 25 March 2009, 22:28:25 »
Ok, got a bit more time this evening so started the re-assembly process!

First up, the first head gasket in place on the 2-4-6 bank. The 2.6 and 3.2 use a metal multilayer gasket which has a black coating on it.



Crank set to 60 degrees before TDC.



First head fitted and the exhaust cam going in.



Front cam bearing cap showing where the green snot sealer has to be applied



Both heads fitted and all 4 cams in plus the cambelt rear cover fitted.
