What makes you think you have a failed head gasket would be the first question...what are the symptoms?  :y

BMW state this head cannot be skimmed.  So if HG failed (or more likely head cracked) it can be bad news.

Has it overheated at some point?

Hasn't Jimbobs mate done this, I know its early days but would be interesting to see how long it runs for.

Yes, his Engineers took 7 thou off, (next to nothing)

Running better than ever at the mo.


edit - same engine, but on a landrover not an omega.

Post by: Jimbob on 09 February 2009, 09:09:45

he says imperial...


is there a metric thou?
wouldnt that be microns?

So they skimmed about 0.25 mm off.

Yes, there is a what is considered to be a thou in metric (mm's!)

Quite clearly the head was not warped if that is the case so no point machining it at all really!

But not what you'd generally use in a workshop. As 0.010"/10 thou is aprox 0.25mm (1mm ~0.040") for everyday use, hundredths of millimeters is plenty small enough. Thousandths of mms equates more to '10ths of thous of an inch'

We work in real thou (mm's).....but then we work with fibre optics and silicon!
