I looked at invoices and rebuild was done 06 and diagnosis of slipped liner done 07 by Davis Performance Landy's. They also did the rebuild. Wish I took the time to fully read all work done + compared dates before I bought.
Actually going by invoices rebuild was done at 240k Slipped liner reported at 247k it now has 255k. Looks like chemiweld has been put in everytime coolant changed. This would mean previous owner would have had to continually add coolant all the time or that chemiweld treatment worked to a certain degree. doesn't make sense. I can't even hear a real knock or anything. mmmmm. Does run a bit rough under load until engine is at full op temp. although give it enough revs and it clears up.
The link Simon put up was very interesting about liners and the head bolts.
