Just back from seeing the Supe. The good news is the head is fine - no skimming or anything needed. The bad news is the block has been damaged on the front cylinder. I took a mate with me who's a good mechanic and between him and the Toyota guy, the general opinion was to just bolt the thing back together. To be honest I couldn't really see what the damage was, but there is slight wear between the barrel and water jacket (I think). Toyota said to rebuild the motor, but it could blow the gasket again, maybe after 2000, maybe after 60,000.
I'm thinking the best plan now is to rebuild it and start looking for either a new block or a new motor complete.
Once again, your advice would be welcomed.
