the cams we fitted were secondhand. we thought that the exhaust cam may have been bent .
The cam broke behind no.3 valve. cam not hitting anything in head clearances ok. buckets removed still no turn. the new cam we installed had exactly the same problem. this did not snap this one. they are 260 by 9.15 lift. .
All the caps had no markings on them which is strange but were put back in the same order they came from.
we ran striaght edge across the tunnel and there are variations in clearance .
strange thing was the original cam when put back in was tight as well. clearanced the caps to allow to turn freely but this shouldnt have to be done.
andrew the cam is in the box with the other one.
the second
