What causes excessive valve cover pressure?
I have a 99' honda accord vtec 2.3L. The oil cap when taken off puffs alot of air, the pcv valve is newly replaced. What could cause this excessive pressure that causes the car to run bad and oil leaks? Need help, thank you!

possible piston ring bypass, unsusal or excess valve guide ware, most are from high milage engines. pcv valve changed but have you checked the hose and where it reenters the throttle body or intake manifol, it may be clogged.
