Is the pcv valve hooked up(sorry if repeat question)

You should verify that the crankcase is being evactuated properly.

If it is, it would seem the engine is tired, it's just how tired is the question.

As for the leakdown test, it's pointless, and good luck finding a pro who even knows how to do one anymore. They are never done in the trade anymore.

If you've got blow by into the crankcase, you've got a sealing problem in the rings. . The leakdown test may verify it, and it may not, but it doesn't really matter.

You've checked the dot's and they line up, so it's not the tc.

If it's blowing the breather off, it's something youa re going to have to deal with.

On the cheap side, if the taper isn't bad, you may be able to get away with a scratch hone,a nd a rering
