Thanks for your suggestion. I'll call Tyler Monday and ask him about their kit.Harshman Racing Engines runs and sells a kit for this.
When I was running My Blockzilla 3! I drilled 2 extra vent holes in the valve spring chamber and it let the compressed air inside of the crankcase have a relief from all of the Compression built up by the under side of the piston! Think about it??? What about all of the air compressed in the crankcase! The 2 extra holes solved my problem and I had 2 - 5/8 hoses off of my ARC BREATHER !! You will loose a lot less oil if you let it Breathe. Jim C.How are people reducing the amount of oil loss in Opens. Sometimes lose as much as 6 OZs in 15 laps. Running PVC valve setup presently, but still puking a lot of oil at 10K rpms. Has anyone tried an "oil return system" and if so how was it plumbed out?
