breather cap shoots off when attempting to start
Was driving 1964 vw in the backyard when i noticed a lot of white smoke. Got out to adjust the mixture and it wouldn't start. Eventually the breather cap shot off with a loud bang and white smoke came pouring from where the cap was. cap appears to have disappeared as well,since it shot with such force. Can anyone tell me what to do?

Crank case pressue building up, check crank case, filter, most likely you have bad ring's when its that bad. I don't now much about vw motors. I don't know how the pcv value and the hose work's on it. Is it over full of oil chjeck that also.

The other member sounds right...pressure in the crankcase. I have not had VW experience but have had cars with clogged exhaust and it created such a back pressure the car would not start and gas spit up through the carb. Had a huge mouse nest in it! Check that...just a thought. Good luck.

Since a factory spec 1964 vw doesn't have a breather cap, can you be more specific, either as to what's under the hood or what went rocketeering? If I were to take a guess, I would assume you are talking about the Oil filler cap next to the generator, but I can't envision a scenario that would create enough back pressure to launch it.
