So I have a slight oil leak issue...and I think the bungs on my headers aren't pulling enough vacuum out of the mill. I just stopped at Wafflebatter's house last weekend up in NY and he had put a electric pump off a S10 on his new 421 SBC...he pulled the cap off the other valve cover and my hand was darn near glued to the hole. I was thinking this would be a "frugle" way to maybe keep the oil leaks down...any input??
