gas in oil

So this is part 2 of my earlier post... I found that there is gas in the oil. When that happens, how do you figure out if it's a carb problem or a fuel pump problem? I don't want to start throwing parts at the car hoping I hit the right problem....

When that happened to my car (before I bought it), it was the fuel pump. The ethanol in the fuel wrecked the diaphragm and it leaked all over, causing a fire. One of the first things I did was to switch to an electric pump.

If the gas was getting in the oil through the carburetor you would most likely be posting, 'My car won't start, my car won't run, my car barely runs and is belching out black smoke.'

There can be conditions where a hot, parked car might boil fuel out the bowl and it eventually leaks past the rings into the oil. But if you have no drivability issues that is not likely the case. The balance on the scale tips strongly to the fuel pump.

I JUST got to your next post (it was further down the list) "Gas from right tailpipe, runs rough" So, yes, NOW that there has been a descriptive isolation to one side (not mentioned in this post) perhaps the fuel pump doesn't apply.

THIS^^^^, is why it is best to stick to one thread per problem!
Multiple threads, and "Part 1" followed by "Part 2"'s get Vairy confusing, and a LOT of important info is lost.
