let it tick over for the afternoon - what's the point in doing that ?
What he means is the head bolts are manufactured to a high tolerance and very specific heat treatments and coatings to provide a consistent friction value under the head of the bolt and a measured amount of stretch for degree of rotation after a set torque is reached. They only retain this integrity a couple or so times before the controllability and elasticity has been compromised enough that the bolt won't function as designed any more.
Standard bolts don't have such a controlled or tight tolerance to either dimensions, coatings or elasticity, so aren't used in such a critical area.
Hello,
Well it's all done and up and running again now. Thanks for the long post DiscoI did have the head skimmed, and what a brilliant service. Collected, skimmed and delivered back for £27+VAT, I don't know how much they took off, it really doesn't look like anything. I used the same head bolts because I couldn't get hold of any new ones before tomorrow when I need to run the landy again. I'm hoping they'll hold out - they look like they've never been touched before, and considering the engine has only done 68,000 I'd assume that this is its first head gasket too. New temp sender and adapter also arrived today so that's in and everything is superb. I thought it was smooth before but it's certainly a lot better. The turbo spools a little quicker and it's made the whole thing a bit quieter (besides my exhaust of course!
) I'm off to Ipswich tomorrow, so that'll be a good 220 mile trip at no more than 65mph. I'll let you know how it does, so far, so good. Its a hell of a lot easier a job to replace the head gasket on a 200 than it was on my N/A. The head also weighs about a quarter of the weight of the N/A head too!
