The first I looked at had a rattle in the engine, Guy in the garage told me " Yea these are a little cammy"
Later it went on to be "That is just a bit of piston slap" Yea right !!!!!
At this point I told him I build engines for a living and this one is not well, he hastily knocked £1000 of the price as I was getting back in my car.
Bought the second one I viewed.
