distributor and camshaft don't mesh right

[Ivan D.]

Well I'm almost ready to drop my new intake and carb in, so I pulled the old intake and carb tonight, then accidentally looked at the distributor gear and immediately got that "oh ****" feeling - the gear seems really worn out on the edges where the camshaft pushes on to make the distributor rotate. I grab my LED mini flashlight, crawl over the engine, and shine down the distributor hole - sure enough, there are wear marks on the camshaft too, just not as bad as those on the distributor gear. Again camshaft marks are on the edges that push on the distributor gear. I'd make sense if the camshaft is slightly more forward than it needs to be, however that's damn near impossible considering the fact I have a button in the front to prevent it from doing just that. If the camshaft was too much behind the other edge would wear out... So I'm wondering, what causes that wear? I have over 60psi of oil pressure all the time, might drop down to like 45 when hot and idling in gear at a stop light, but it hardly ever happens. So there is plenty of oil getting up there, and the camshaft lobes don't look bad at all... Any ideas?
