How sad to read that. Same old, same old.
Over the past twenty years I've been using the Internet, lost count of the times I have seen comments like these.
Also lost count of the 620ti cars I have bought from frustrated previous owners about pro-work on their cars. Actually, it's about ten.
Indeed - this was a so-called specialist in this job, but I believe he got a "lad" to do most of the donkey work, like reassembling everything. And he must have been incredibly ham-fisted and inept, so the boss should have checked his work afterwards, at least.
20 thou ,,, good grief! Bet it didn't need that much if any at all.
We always skim heads mate. ( even if they do not need it!
Well he said he'd started with a smaller amount, but it wasn't enough so he had to do more. I don't know how much is safe, but I wish I'd got another head instead, now! Are they still available anywhere?
If I did not have too many cars on my plate currently, I'd be very interested in making an offer on yours.
That would be good - what about a swap?
I can give you two for one! (I have a 1995 model in the garden).
In your position, this is what I'd do. Go on here and any other MG and Rover sites you are a member and ask for recommendations of competent folks ( there are some around ~ trick is finding them ) to look at your car and diagnose best course of action. From what you say about overheating, the CHG may well be damaged ( they rarely fail particularly even on the T-Series ).
I don't actually know of any other sites. And I was hoping this thread would elicit the sort of advice you mention, but nothing yet. I seem to remember that last time I got two recommendations, one in Kent I think (Russell?) who when I contacted him said he didn't do them any more, and the one I actually went with. Who said they could do it at the roadside unless the head needed skimming... but then changed their minds and collected it on a truck.
I didn't mention earlier, that apart from using a bit of water for the past few months, after overnight parking it has also had a tendency to start on three cylinders, with the fourth joining in about a minute later, so I suspect a slight water-to-cylinder leak had developed, and the overheat due to my stupidly leaving off the cap has made it worse so it's now a fully blown gasket!
Have changed six CHGs on 620ti project cars. It's not rocket science.
Maybe not for you!
I'm just not up to it these days, and I don't have anywhere to do it. My hands are just too big and clumsy to reach down around the engine in a lot of places (biggest job I've done was replacing the water pump, and I only just managed that). And I think it really needs a new head, because most of the exhaust manifold stud-holes are stipped to a greater or lesser extent.
Aside: something I found out from the RAC bloke: if I hadn't been a member, they charge £7 a mile for towing!
