Thanks for the tip, 51 ashton. I will disconnect it all, then hook everything back up one at a time until I find the vacuum leak (if there is one).
Regarding the valves again: When I set my engine to TDC (the line between the UC mark), both intake and exhaust valves on cylinder one are closed, and both intake and exhaust valves on the number six cylinder are open. My question is, should the exhaust/intake on cylinder six both be open at the same time, or should there always be one open and one closed (same goes for the rest)...
