So I know its a pain to do....but how much of a pain is it? I mean if I'm jacking up the motor to do the chain tensioner job, mayvbe the timing cover ain't that much more work? I know the water pump and crank pulley have to come off and probably lots of other stuff. But I think once the motor is jacked up a bit its probably not so terrible? Does it need to go up higher than I'll do when I do the tensioner. And I just did the engine cover gasket last week....other than cleaning and redoing the two rtv spots, I can keep that new gasket in place right? Is the crank senor in the timing cover and a new seal warranted there?
