Many things could cause this, a misfire, temp sensor, clogged air filter... Has the check engine light come on?

I changed air filter & all spark plugs & found a large vacuum leak at the intake,rubber seal had large tear at intake by clamp. There doesn't seem to be adequate pressure on fuel relief schrader valve, if fuel pressure regulator diafghram is ruptured would this account for fuel in the oil ? The check engine light is not on.

Chances are because of the vacuum leak, the fuel isn't getting burned and is getting past the rings. Have you repaired the problem?
