7M "Ventilation Hose"

Pan Evac?

Into the downpipe?

Does the car have mufflers?

I just replicated the stock system in my car adding a catch can and a real PCV valve.

No mufflers, was going to do it at the end of the downpipe after it went straight.

Guess it all depends on the amount of blowby you see under boost, mine easily overwhelmed the stock pipes/hoses so I changed to -10 and that sorted it.

I'd still run a PCV Valve to the TB it's going to close soon as the engine see's any boost but as Nick noted it's going to keep the engine clean/happy/economical for normal driving, I'd also weld in a 2nd Evac Bung in the down pipe capped off for now but there just in case

Think I'd be installing the bungs further up the pipe towards the Turbo as well.

Ya I was going to run dual pan evac. I need to research more on pan evac I don't know technical info on it I just figured at the end of the downpipe would be best.
Would you run the baffles in the valve covers? I have mine drilled and tapped when I powder coated them so.

Should I run the special pan evac valves? Its a 4" DP and 5" back

Yep baffles are a must or it's going to pull over raw oil and smoke like a bitch, the evac system work on the Venturi principle so it's better to have the bungs where the gas speed is quite high past the fittings (this is why it doesn't work well with mufflers as they cause a reversion/slowing of the gas).

 

[stevenr816]

What about the fittings? Run standard ones or the ones with a check valve?

 

[IJ.]

I'd go with the check valves.

Hey guys i recently did valve cover gaskets,#3gasket,cleaned pcv tube on top,found about one inch of oil in spark plug valley,whoever worked on this last screwed up the 14 mm plugs,no sealant,crossthread,a mess,anyway got that fixed,now the front vent hoseunhooked it blew through it,it just makes a circle from crankcase to valve cover,my plan is to cut this hose use a 90 elbow pvc pipe with a filter on end pointed up so oil doesnt travel up it,on he pipe coming up from block going to do the same,put a filter on top of it to,as long as it breathes whats the problem,,it seems redundent to me,imeant pcv rubber hose instead of pvc elbow,as long as it can breath shouldnt be aproblem ,any thoughts,thanks,mmkkpro

My thought, other than you need to use the space bar more often, is that metered air matters.
