I found I've been getting fuel in the crank case ('71 Westie). Its either coming in through the carb (new) or the fuel pump (old - sitting for 25 yrs.). I suspect a torn diaphragm - Bentley shows that the '71 fuel pumps are not serviceable other than a filter & o-ring . I've been prepping the body for paint , so other than moving the bus in and out of the shop it hasn't been driven - hopefully no engine damage. I don't suspect the carb just because the engine fired up and idled with no hesitation or sputtering - I don't know if that's enough to go on. Before I start pulling things apart , I thought I'd check in with you guys for any tips\ideas. From what I've read , the knock off pumps have gotten poor reviews.

Are you sure that it is fuel and not condensation 2 years in a row my vw filled with water during the winter even after a fall oil change due to the fact that I was starting it and pulling it out into the cold while working on other projects there was at least a litre so much the water poured out when I pulled the valve cover.

Hi stude - I don't suspect water as it doesnt have that milky look to it . The oil I drained from the engine appeared to be thinned out and smelled of gasoline. I took the pump off today , and as I mentioned, the diaphragm can't be accessed or replaced. I'd like to somehow test it to see if that is the problem.
