in my 318 while changing the oil i think there was some gasoline in with the oil. the fuel pump is leaking, haven't really looked at it, probably cracked. could this be a cause of fuel in the oil? or is it something elses? time for a new motor? thanks in adnance.

I had the same problem in my 2.3. Rebuilt carb and problem went away. Hope this helps. Motor did not last long after that.

ok, how about this, what are the possible ways fuel can get into the oil? i know it can be poured in , but that didn't happen. any help appreciated.

i'm not sure how the carb could be involved but i do have another to swap it with.

anyone got a 318 in the okc area? hopefully i won't need it.

I would say change fuel pumps also how fresh is the motor maybe rings does it smoke any. Just a thought.

It can leak in from the fuel pump diaphram. It can leak past rings if they are shot (blowby). On some chevy's I have seen the lead plugs in bottom of bowl start leaking and it runs in past rings when sitting because the bowl empties into the intake. I would say try the fuel pump first and change the oil and filter. Cheap and logical place to start.

Carb or fuel pump I would think if the carb has a problem you would have a hard start or run crappy when you start it.It sounds like the fuel pump might be worth looking into farther.

Fuel pump. Most fuel pumps have a weep hole that will start leaking fuel if the diaphram starts leaking. Once past the diaphram it can go directly to the crankcase. It's the best place to start, since you already know it needs to be replaced.
