6 years 73k no codes.... Yet..... Lips Sealed

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.

Probably

...... 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. Huh

Reply #193 - 25. Mar 2009 at 23:28

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.
