914World.com _ 914World Garage _ fuel in the oil
Posted by: Graham du Toit Aug 2 2017, 11:04 AM
Good evening from South Africa.
I have a 1970 914 that runs on weber carbs. I have had the carbs serviced and have changed all the fuel lines.
I however find that I am getting fuel in the oil and it appears there is a fuel leak between the head and the sleeves.
What coud be the cause of this?
Thanks in advance

Can't answer your question, however, back in '79-'80 I lived in Kinross and owned a 914. Orange, might have been a '71.

Turn the ignition on and look down the carbs and see if you have fuel over flowing down the venturis. Floats not set correctly or bad neddle valve could cause flooding. Change the oil.

Even after servicing, the carb floats could be stuck. It can happen on re-assembly. What you're describing is a very rich fuel mixture and/or raw fuel flowing directly into the intake manifold.

I had a similar problem with dual Dell carbs a few years back--floats had started to hold gasoline (so they no longer floated as designed), also bad (sticking) needle valves. Accelerator pump diaphragms were leaking too, though those were secondary sources of the leaks.

Gas in the oil will kill your engine. The lubricating properties of the oil go to shit after it gets flooded with gas. I had that happen to me in my Second 911 Porsche and then I got the dreaded rod nock. Yep, change the oil.

Floats set wrong, needle valve is dirty
