After the initial remap (see Compcam speedster remap) the owner returned for verification of the timing of the camshafts.

So we took off the valvecover and we saw this.

The 2nd cylinder seems to be missing a hydraulic lifter!

Looking a bit furter we found what happened to it..

This can very well explain the problems the engine has. Unfortunatly we couldn’t source a new hydraulic lifter today. So we need to wait for parts and see if we can replace it. The exhaust cam seems to have some damage to the lobe, so that needs to be removed.

Using special tool KM6148 we checked the camshaft timing. The timing is spot on, so that doesn’t seem to be a problem.

So again, to be continued..
