Nope....it's the boost coming thru the lines from the Throttle Body and going to the PCV valve.

What is the pcv valve?

It's the thingy in the left side of the cover do-dad that is on top of the engine. It's got a black hose thing running to it from the siver whatsis where the air comes in.

Otherwise known as Positive Crankcase Ventilation valve. Boost blows oil out where it shouldn't.

I just did a but load of research on all the pcv stuff and from what I understand is the pcv system routes all the crankcase gasses from the crankcase (to prevent sludge) back into the throttle body. The valve regulates the amount of these gasses going into the intake and if the pressure in the intake becomes greater than that in the crankcase its supposed to close to keep pressure from building up in the crankcase right? Atleast thats what I read. So if the pcv valve is operating correctly please tell me why you would need a check valve?

I have highlighted the area of your research that makes the Check Valve a good idea.

When I am pushing 26 lbs of boost through the intake, I don't want to rely on a $3.00 PCV valve to keep me from dumping all my oil out of the breather (I kinda need the oil on the inside).

Plus our pcv is a piece of junk!

[7055]

Anybody tried putting some other kind of crankcase ventilation on there and getting rid of the pcv? Isn't pcv bad for engine life anyway? Just wondering, I Know it would probably be illegal because of emmisions or something but same with alot of things on these cars.

And where do you get a checkvalve?

How are connecting rod bolts insurance against a spun bearing? Isn't a lack of oil that would cause a spun bearing?

Thanks...good info, btw...any used nology wires and plugs? will they do more long term damage than short term good?

[Wozzy]

So I figured I'd post here to see what everyone thinks of this setup and maybe possible think of a better route to go, or anything really :P.

I really want to go with the 3" MPx dual exhaust but I'm kinda leary that it's going to be very loud, I can tolerate loud, but how loud are we talking? So that kinda why I'm leaning towards the Mopar 2.5".

• MPx Intercooler
• Injen Short Ram Intake
• AGP Uppipe (B.O.P, HKS flange, HKS SSQV)
• Granatelli spark plug wires
• AGP Wastegate
• Mopar Stage 1
• MPx 3" o2 housing (Still deciding...maybe pair with the "Mopar Cat-delete kit, or just get the Mopar kit instead, opinions?)
• Mopar 2.5" exhaust
• Eibach Pro Kit springs

Not wanting to go too crazy, goal is to keep it in good working order, don't want to upgrade to a bigger turbo. Maybe give me a rough estimate of HP and if this is a good setup?

Thanks

Must you gap the NGK plugs?

[bobczar]

Its always good to check the gap on the plugs. You never know if there is a factory fault that caused the gap to be larger than it supposed to be.
