Title: Head Need Skimming?
Post by: Darth Loo-knee on 07 February 2007, 22:43:56

If I bought an Omega with a Head Gasket in need of replacement would it be advisable to get the head skimmed?

Thanks Again Guys

Every time with an alloy/aluminium head. You can usually get away with a very light skim - more of a reface really. Alloy heads distort when the stretch bolts get released.

Wasn't sure if Omega's have Ali heads...
Whats it cost about to have them skimmed any idea? Trying to remember how much i paid a few years ago on an old Rangey!

Costs about £25 per face up here, that includes cleaning before they give it back too.

Mark would know about this..

But I recall something about the inlet not sitting right if the heads are skimmed on this V6

Would recommend getting them measured and tested, before skimming....

You dont need to skim them unless they are warped....never had to skim a V6 head yet....just remove the bolts correctly!

Dont skim them to much though becuase its a V engine and the inlet manifold gets out of line with the inlets...

yep i have to say that i wouldnt ever skim any head unless it was proven it was warped.

Theres a limit to how many times a head can be skimmed so use only as a last resort ( or if its a k series rover)

I skimmed 60 thou off a head once for compression ratio purposes

If you're doing the job because the HG has failed it will probably need refacing due to corrosion at the point of failure.
