Anybody have issues with the quality of the cosworth STi cam.
Long story short, I have a built motor that uses these cams, after 300 miles of break in I noticed some knocking noise from cylinder 3. My builder and I took a look as we thought their was something wrong with the shim or bucket. To our amazement the lobes on the intake cam were worn down
The other 3 cams were fine, so I wondering if anybody us had quality control issues with these cams?
