Camshaft bush

I see from the club spares you can buy the camshaft bushes as ET64 Camshft Bush Oilite and ET64/1 Camshaft Bush Lead Bronze.

Which one is recomended? I know originally they were oilite so the bush had some lubrication at startup before oil flow got there, but does lead bronze have an advantage.

Cheers,
Simon.

Hi Simon

For what it's worth, I'd use ET64/1 and ream to suit the cam spindle. Oilites aren't the best material (pressed powdered bronze) for reaming to size and concentricity, so the fit tends to be determined by the size of the hole in the cams and that's not a great way to control a critical tolerance.

The inside of an engine is never that "dry" that its imperative that an oilite bush is used. Oilite bushes are primarily for external use. Go with the Leaded Bronze, phosphor bronze or Aluminium bronze.
