How do you adjust valves on 71 VW bus?

Adjusting your valves on the 71 bus is quite easy and it's only one of the things you should do every 1500 to 3000 miles. I would strongly suggest buying a copy of "How To Keep Your Volkswagen Alive". I own a 1971 VW transporter and it's the only source that I've found that has decent pictures and explanations on how to do all the up keep on my van. Good luck with you valves. Adjusting them will make you at one with your bus.
