I was examining the breathers today...it looks like the cheap crimped on design is actually allowing oil to leak past. So I cut the nipple that goes in to the V/C shorter, and put some right stuff (not pretty, but will tell me what is leaking) around the crimped area on the breathers. Going to drive it and see if it still leaks some there. I also now have some oil seeping from the front oil pan seal

Unfortunately my valve covers only have one hole in them, and they are baffled, so I am not sure how they aren't doing their job? Is the fuel pump block off plate a good area to measure vacuum from?

I tried looking for SBM valve covers that have no holes in them so I can make my own, but I can't find any
