Re: Fuel in my oil
 

Raw fuel is being dumped in at least one cylinder, washing the protective
oil film off of the piston rings, collecting in the crankcase, diluting the
oil and causing great wear to the block/bearings/rings and any other point
at which engine oil is acting as lubrication. Get this fixed *immediately*.
Have a dead miss? maybe the plug in that cylinder isn't firing, so it might
be a relatively simple cure. In any case, after repairs, a couple of oil
changes to flush the contaminated oil out of all areas of the engine is in
order. In any case, don't use the car until you have it diagnosed by a real
mechanic or you might cost yourself an engine.

Re: Fuel in my oil
 

To raise the oil level is a LOT of fuel in the oil. It is unlikely that
it is entering via a cylinder. I don't know what year you are talking
about, but if it is older and the FP is mounted on the engine, look for
a bad diaphram on the fuel pump. Could be entering there...

What year CRX? Does it have a carb?

That's my thought. If it isn't a bad fuel pump (as you describe) the engine
should be running mighty badly to dump that much fuel past the rings.

Once the problem is found and fixed an oil change is definitely in order.
I've heard the argument that the oil will still work okay with a lot of fuel
in it and the fuel will gradually burn off through the PCV valve but I don't
see the point in letting it go.

That doesn't sound like a valid argument to me. The excess fuel will
function as a solvent thinning the oil and reducing its lubrication
effectiveness. If the original poster's car is carbureted, then it could be
that the carburetor is flooding. This would be the first thing that I would
check.

Dunno - I've had float valves jam and flood the engine so it wouldn't run
and still not reach the point where it was obvious in the oil. A bad
engine-mounted fuel pump can add a steady stream of gasoline. If the engine
has been running okay the fuel pump is the way to go.

Good points, I guess that both the fuel pump and the carburetor should be
suspect. Thanks.
