for anyone that has crankcase pressure issues
 
What is the best setup to relieve the excess crankcase pressure? I am looking into the http://www.saikoumichi.com/ stuff.

Reason im doing this is because i have so much crankcase pressure that the oil is being pushed up the turbo return line from the pan and leaking oil out of the Vband on my fp black.

Just wanted some advice or suggestions here. I want to run around 40psi eventually, but right now im only running 32 and experiencing this issue. What is the best route and way to go about this?

drill bigger holes in the valve cover on the existing holes already on the valve cover and route to the saikou cans? i emailed saikou and a few other vendors to see what is recommended / can be done etc.

Maybe the Kiggly hla pressure regulator would alleviate the situation.

I already have that.

try and disconnect your pcv valve from the intake manifold.

krankvent, and/or hal's oil cap

i will do that, but i dont wanna just spray it to the ground, so im looking for the best route to go about this while maintaining the least amount of oil as possible. I believe my first 2.3 failed due to this reason.. it was pushing the oil up there and the turbo was slowly burning it off without showing signs out the tailpipe. im glad i just caught it this time.

Wow... Yeah Boost has a good point. I've run the Saikoumichi cans since '07 and love them.

hal's oil cap i heard is no good because it pushes to much oil out of the valve cover, so it must be recirculated back into the motor. the dsm guys recirculate it into the balance shaft inspection hole ,but i doubt that can be done on a evo since its so close to the exhaust manifold.

Pull out the barb on the transmission side of the valve cover and the PVC valve. STM and several others make press in -6AN fittings, run lines from both to a catch can.

As far as I know I don't have crank case pressure issues at all...I've been running MAP's little crankcase vents for a while on another catch can setup but I got rid of that catch can and plan on purchasing one of the DC3s before december...Hal's vented oil cap looks very interesting also but I feel a lot of oil would come out of there even if it has baffling in it...Even though I'm not having issues I guess the less crankcase pressure the better...

ya you wont. it has lots to do with my built motor. i never had much blowby with the stock motor. Hal's cap i was told by 2-3 people that it releases to much oil and isnt safe for a daily driven evo unless its recirculated back into the pan.

are you venting the can to the atmosphere then as well with a breather filter?

tscompusa2 Nov 14, 2010 05:06 PM

i have this also in the garage. would this be of any benefit to run along with the can i install? http://www.maperformance.com/kracka-...acuum-kit.html

Im also haveing problems keeping my dip stick on. I got a HUGE spring holding it down now but after a couple hard pulls I pop my hood and the stick is down but oil is around it,....

So finally yanked the valve cover and drill and taped a HUGE threaded nipple so that helped a lil im guessing but still want to run the STM AN fittings to be sure.

I PMed Em from STM and he said they could build me a nice kit so ima go with that along with the extra nipple I alrdy have nd see if that down it,...
