Yo, would of been a handy hint earlier today before we fitted it
So for those of you that one day find this thread in a search.... The cam doesn't pull fully up inside the vernier. The rear face of the pulley pulls up tight to the retaining bearing plate (not sure of the proper name).
We took measurements are 0.015", 0.010", 0.005" and 0.003" both before an after full lift and took an average of all 4 readings.
We didn't use the flat washer on the back of the vernier. But as mr Fishead said you need to be careful with the locating dowel which as it can be suhed out if the cam isn't aligned properly. The timing cover did need a slight tap to clear the head of the bolt.
We used the inlet valve on cylinder 4 (waterpump end) to se the timing.
