gas in oil pan
Well, been having gas in the oil lately. I changed the fuel pump, and thought I'd solved the problem, but it now its back. Been driving it very little as I don't want to wipe the bearings.
Other than getting a different fuel pump, what other things should I consider?

Re: gas in oil pan
What Chris said...either the carb is running too rich, or the floats are set way to high, which dumps raw fuel down into the cylinders, which in turn find their way past the rings and down into the oil pan.
So how much fuel are you getting in the pan anyway?
Interesting related story: Years ago I bought a '69 Datsun pickup from a friend to use as an around-town parts getter. I paid $200 for the truck because he said it had a rear seal out in it, and he'd parked it in his back yard where it sat for several years. It would fire up and run, but oil was literally running out the back area of the engine. Got it home to the shop and a week later decided to get started replacing the rear main seal. Went to drain the oil and instead of the 4 quarts of oil, I got about 2 gallons of liquid out, about half of which was gas. After doing some troubleshooting, I found out that the fuel tank on this truck had a vapor line which plugged into the base of the carb. The previous owner was using a non-vented gas cap, and when the tank built up vacuum, raw fuel would get sucked into the vapor line and down into the pan. Once the pan filled up, it had nowhere else to go but out past the rear seal. I simply had to change the oil and filter and replace the cap with a vented type, and drove that truck around for several years. (Needless to say, the previous owner was fairly ticked off that it was something so simple and and he'd let the truck go for so cheap!...LOL)
