hey guys and girls.. 1)i currently have a engine that will be running around 20psi...it uses a rajab tappet cover and has 2 dash 6or8 not sure breathers in the rear passanger side with a baffle welder over them...i have had trouble with it just filling the catch can. so i fitted the old tappet cover with some 20mm breathers and bigger hose and now i dont have a problem.. so guess the question is wat do i do to the rajab tappet cover to make it breathe nd not fill the catch can? 2)also has anyone used hyperlite silicon top pistons/hastings rings what power/boost level should these be able to handle PLZ HELP...but only if u know wat ur talkin about
