Hello Graham!
The problem is the young lad had been using it, with the known fault of the coolant transfer pipe leaking, trying to pin him down to a straight answer is nigh on impossible.
Personally I have never overheated it, but it may have happened, I just don't know.
I have had an offer of an engine (complete) including delivery and 90 day warranty for £325!
I can also get one for £100 with no warranty plus pallet to Scotland for around £60 but I'm not sure of the guy. That second one is from a chap on Totalcarlton that has been the subject of quite a few posts, not altogether the best recommendations either.
I think I'll have to bite the bullet on this one, get a new clutch fitted and the new water pump I bought last year as well.
I have to bear in mind the lack of facilities over here in Scotland, plus I don't have a lot of time over here to do this myself........ Still it means I will have an engine to strip down for spares if needed, maybe even sell in parts to recoup the outlay!
Your thought mate?
