I've been procrastinating away the winter, but it's time to address a few items before spring.
Oil leaks - Ok, this is my biggest problem and is the reason for this post. I'm getting a lot of crankcase pressure since I added the turbo. Off boost I've got no oil leaks. On-boost I've got leaks from the valve covers and pushrod tubes (both new and in good condition). I've got the rocker-box vents plumbed up to the spark-arestor where they are joined by the oil-filler vent hose and this three-into-one arangement then goes via single 5/8" hose to a home-made catch can. Do you think running these as three individual lines (rather than plumbing them down to a single 5/8" hose) would cure the problem, or do I need something more agressive in the way of venting/scavenging? -Ben M. |

there is your problem! while the oil-filler neck always has positive pressure, the head-vents will have positive pressure at and above idle but will turn to *negative* pressure (sucky sucky) on higer rpms. for the catch can to be most effective, you'll need to route each to the can individually.
