 |
|
| Hi everybody, this is my first post. I searched and found nothing, but if I missed it, sorry. My 1970 bus (first time vw owner here) has a 100% stock 1600 engine. I noticed when I got home it has a small puddle underneath it and was dripping gas from the cooling fins on the #1 cylinder. I checked the gas line and nothing was wrong, no gas puddled on the tin inside the engine compartment, but it kept dripping underneath.. So I went to start it (not a good idea I know) and the starter hesitated then I heard a loud spraying noise! I stopped and had a look and there was gas everywhere underneath the bus, dripping like mad from the cooling fins... For the past week I could smell raw fuel while driving, but didn't notice it leaking. The last time I drove it was Friday, I filled the tank then and parked it for the weekend... So what the heck is Wrong?? Any ideas? If you are still reading this thank you. I really appreciate the help. I wont be driving it at all and I'm having it towed to my mechanic on Thursday. Thank you! |

Your needle and seat were leaking and the overflowing float bowl filled the lowest cylinder with gas. As for the gas everywhere now you likely hydraulic locked the engine when you attempted to start it and stretched the cylinder hold down studs

or cracked a cylinder. Better check the rod to be sure it isn't bent either.

I recently found that rust inside the fuel tank caused the float valve to stick open and flood the crankcase with gas on a 1970 bus. Pull your spark plugs and crank the engine. This will get the fuel out. Pull the carb and check the valve and maybe replace it. Look at your fuel filter to see if it's loaded with reddish brown crap. If so, plan on pulling the tank.
