I cannot remember much about the last FIAT engine I worked on. I do know it was circa 1962 and it was a 1600S Cabriolet twin cam with a fantastic efficient oil filter mounted on the crankshaft nose.

You had to remove the cam chain split link and split the chain to remove the camshafts otherwise the procedure was about the same as a Jaguar XK. Most probably you have much more recent experience as there is some very ingenious tooling out there to cut down the working hours.

I can remember buying a “Craftsman ”tool that you have described, in the USA. On that occasion it was employed replacing springs and seals on an OHV with an F type head.

Better get back on track talking Jaguars or Rob will have us shot at dawn!

Alfa was similar to Jag. Shim was under bucket but small & capped over the valve stem. Cams out. The only easy OHC on follower engine I know of pre hydraulic lifters was the Alfa Sud boxer engine. Twin cam lobes per follower/bucket. Hole drilled through cam between lobes through which you stuck an Allen key and directly clicked a mechanism in the bucket to adjust lash. All you required other than the Allen key was a fancy Alfa twin pronged tapered feeler gauge. No stripping required other than removing the cam box covers. A very neat design.

I think Fiat did build a 1.6 litre TC engine where the cam ran on the shim pad on top of the bucket/follower. Do not recall the adjustment procedure.
