Sorry to hear about that cracknut. Scot Burner used to tie down his dipstick for the same reason. I haven't had a problem (yet). A good size catch can in the PCV valve line will keep the vacuum in the valve cover & crankcase and catch the oil, but you'll catch so much you will have to empty it back into the engine after very session or two.

I have heard of people drilling holes in the valve cover baffle that sits under the PCV valve to allow the oil to drain away from the PCV valve while in long right-hand corners. Next time I pull my valve cover I plan to do this.

 

nice write-up and thx for sharing Rob!

 

Rob, I just ordered the parts to do a 2.5" brake duct system. Hope to do it during my two week summer brake in June, if not earlier. Grad school sucks when you got to do 72 credits in 6 quarters, plus a thesis. I don't know how my sister got her law degree.

 

It took me 4 years part-time to get my graduate degree so I know what you're talking about.

 

I would like to know if anyone has input and/or experience with the Krank Vents I posted about in post#41 above.

Rob, do you have any input on these?

Thanks guys

 

I looked at their website but couldn't really figure out the theory of the vent's operation. So far my capped PCV line & vent in the large valve cover hose is working great so I don't need anything else.

 

Did anyone try out those crank vents? Marksh2? I want to do this DIY soon and am looking for info...

 

Not true. The PCV valve is simply a one-way check-valve. You can blow through it one way but not the other. It is not vacuum operated.

 

I used them for two seasons. The second season I must have picked up enough grip/speed to overwhelm them. I was puffing a monster cloud at WGI after the uphill esses (3-6) when I would shift for the back straight. Skip it and go the catch can route.

 

There is some good info on catch can setups here. We should try and add this to a catch can FAQ of some sort. I'm thinking of just running two catch cans since there is a part throttle vent and a WOT vent.
