Get rid of the filler caps. Nothing but problems with leaks when you have alot of horses

It does do **** for blower cars. I pushed the seal out of the timing cover on the dyno because the pcv system wasn't able to handle the amount of crank case pressure. Now I have both rocker covers vented to a vented catch can. So If you start to make some big power you'll need to vent the engine.
