My exhaust camshaft has been damaged (VW1.8, 20v, non turbo).

I've had trouble finding the specific cam for a non-turbo engine, but
have find one for a turbo engine.
Physically, they are very similar, apart from the camshaft gives around
1mm less lift (i.e., the cam lobe is higher on the non-turbo camshaft).

Any idea if it would work with this cam?
I'm assuming it would run, but what problems could I expect - reduced
power and possible burnt valves are 2 suspects I immediately thought of,
anyone have any views on it?

sounds as though it would be a milder cam than original and so should work
fine.

Yes it would.

Loss of performance from lack of lift and increased duration.

No reason you would burn a valve, but expect a bit less power. Not much
less, and possibly not even noticeable.

I would check the profile of the cam and get the actual figures.
Duration angles and lift. the turbo cam may be very detrimental to the
performance.

A suggestion, not sure what has been damaged - lobes or journals, is to
ask a performance shop can they get the camshaft reground or an exchange
one.

or ask a dealer if they have any warranty ones kicking around. They
change heads as a unit so may have a cam.
