Is there a way to determine the correct position of the exhaust (front) camshaft, independent of the gear markings? (i.e. the shaft itself).
I torqued the timing belt pulley counterclockwise with the camshaft gears stopped by a rag (don't ask) and damaged the timing set-up.
I think that I twisted the timing pulley counterclockwise on the exhaust camshaft, or possibly moved the camshaft gear on the shaft itself.
The car runs well, but makes a very subtle 'exhaust valve noise' - that is, a little like a motorboat (not quite as much as a Ford 302 with the valves burned wide open!).
I would like to verify all of the parts in correct timing. I know that there are 2 sets of marks on the camshaft gears: I want to check that these are set up right too. Do you know, is it possible to twist the gears out of line?
Are there markings on the shafts themselves?
Thanks for your comments - Jack
