I have just fitted a new camshaft (pw3) and I am looking to check the cam timing , when doing this do I have to set the tappet clearance and then measure from the valve spring retainer , what amount of lift is considered the open and closed point on the cam , also is it ok to turn the engine backward with a spanner on the end of the crank ? engine is in a stand on the work bench
I have checked the springs for clearance from coil bound and one of the inlet is a bit tight, needs about another 20 thou is it ok to run without the heat insulating washer ?

All comments and advise welcome
thanks 850Sam
