New steel pan? Or cast alum? I like a paper gasket with cast pan. Light coat black rvt on both sides and torque wtench to tighten. Look for gouges in both surfaces. Or over tightened pan bolts bulging the pan rail on gasket side. Good luck man
Steel pan
This is the pan I bought since it came with the filter.But I used the reusable gasket I already had,not the gasket that came with the pan. http://www.manciniracing.com/ma727chdepan.html
