2.9 has gas in oil

[Schnot]

My uncle just acquired an 88(I think) bronco II. It starts and runs but it's getting a substantial amount of gas in the oil pan. Any ideas what could cause that?

The first thing I would think would be rings and low compression but it doesn't smoke hardly at all.

Imagine if a spark plug was bad (or its wire), all of that cylinder's fuel is unburned and washing the cylinder wall. Idle it and pull one wire off distributor at a time. If one makes no change in idle, tada.

A single bad plug wont do that. Leaking injector(s) or a bad fuel pressue regulator would be far more likely causes. Check the fuel pressure.

^ This^ I would be going straight for that fuel pressure regulator.

Agreed. I'd pull the vacuum line from the regulator and inspect for fuel in the line.

Ok. I'll check the regulator.

How do I check the fuel pressure on these?
