So I have a stock M1009 that I have put a KN filter and 40 series exhaust on. Now because of the increased air flow I am building up more crankcase pressure as evident by the seepage from my rear main seal. The seal needs to be replaced as I want my truck 100% leak free which it almost is. When I put the new seal on I will still have the increased pressure so the air flow increase is just making the problem more prevalent. I have been looking for a replacement breather/oil cap but can't find one. I would like simple fix as I want put a cold air intake on but haven't because that would increase the crankcase pressure even more. Thoughts?
