(1) I have an engine with the center camshaft journal is .002 undersize and the center block bore for the cam journal is .004 oversize. what is acceptable wear? and what problems if any would come from wear that is more than acceptable. bushings are not a consideration at this point....just a question. (2) the front cam plunger spring currently sold is about 1/4" shorter but a little stronger than original. is it best to reuse the old spring, the new spring, or obtain a new one locally that is the same length? (3) does the plunger cavity in the front cover wear and deepen? thanks.
