I have a 350 4bolt .30 over (355) all the standard stuff, 2.02 heads, rollers
10.4 - 1 comp. edelbrock airgap intake, etc... it runs perfect and i only have about 50 miles on it. still trying to break it in. my problem is that i blow oil out of the pcv valve hole and out of the front seal on the timing cover. what can i do to stop this? i have put a larger pcv valve on it and a new larger breather on the passenger valve cover. still when i start driving it i start dripping out of the timing cover harmonic balancer seal. and down the sides of the valve covers from the rubber grommets for the pcv and breather.
Thanks
