What Are You Doing To/With Your Car Today?

thunk I`ll start it up and see just how much vacuum I am getting on the pan evac system I rigged up last friday , ''drivers side only'' , interesting to see if it works w/ my home made exhaust system ----I have had trouble beleiveing they would have enough vacuum to overcome the check valve . I have messed w/ 3 diff check valves (or whatever thier called) , and this one seems to be easier to open than the other two.---------------more to come

Follow up , the evac line seemed to pulse , blowing a little untill I put the valve on it up top , ''SUCKED QUITE NOTICEABLY THEN -WEIRD! ''
Reved the engine up to about 4200 a few times , w/ valve and w/o valve installed on valve cover, it lowered my vacuum gauge about 1 1/2'' installed , , took it off and sealed the cover w/ a twist on cap , vacuum gauge went back to 5"- ---took the line and valve off the car , and capped the exhaust nipple . Guess my home made mufflers have a hair too much back pressure to run the evac system ---??????????? comments ?
