Of dear. Sometimes worry about the now minor oil leaks from the points cover area. Caused at least in part by the Helicoil job that was done . . . Not nearly as many XSs in UK as USA. Therefore much less chance of buying s/h cylinder head or decent used engine. Now, spotted an complete engine on ebay. Looks very clean, claimed to be low mileage, said to have good compression. But it's a 2F0 engine -214*** which suggests 1980 SG? I don't think that gives a problem, looked around on this forum and it seems to be basically 447- type. Thing is, I need to be dissuaded from going and lashing out serious money just to have a spare engine/sort an oil leak. Comments invited.
