Whats the correct PCV for my setup?
Whats the correct PCV for my setup? I know this is beating a dead horse, as ive read about 40 threads on this, but before i start buying parts i figured id ask for some advise
LQ4 with .030 ring gaps
cut 317's
228/228 cam
Getting ready to put it on the bottle, which is the reason for the big ring gaps.
I have the front passnger valve cover going to the throttle body port and then just a 3/4 line going from the driver rear PCV port straight to the ground
When im sitting in traffic, and the sun comes through just right, i can see the crank case fumes making it through the vents. The car stinks. I stink. I smell like a oil pan after drving this car.
So not really knowing how this engine is suppose to be, what should i do to A.Eliminate the stink and B.Properly vent the engine?
I really dont think its a compression ring issue, im hoping its more from the large ring gaps. I could leak it down, but id rather not know. The car rips and runs real good.
Will a stock PCV setup be adequate? What style OEM setup should i go with?
Ive noticed my driver valve cover doesnt have the nipple like the older LS1 drivers valve cover.

What valley cover do you have on your engine, LS6 or LS1?
FYI, the LS6 cover has a port on it in the right front that goes into a short U shaped hose, then into the intake manifold port on the passenger side front.
The LS1 cover has no port (crankcase ventilation port) on it.
The way you have it setup now it's only venting crankcase pressure, and normal combustion blow by is continuously contaminating you oil instead of being pulled out and sent back through the intake manifold (preferably through a oil catch can first).

nice! thanks!
So just to be clear, the factory-ish setup would be the passenger valve cover port to the throttle body port AKA fresh air inlet
Then PCV in the drivers rear valve cover and that then goes right to the intake manifold to get manifold vacuum?
And thats where i would install a closed catch can to avoid a oily intake. Or just run it like stock and have oily ports

the port going to the intake manifold needs have built in restriction (look into the fittin g on your valve cover) or like a valley plate which also does.. if it does not then you must use the stock pcv valve in line, otherwise you will send an unregulated vac signal to the crankcase.
Best is subjective. When I went with a LS6 valley cover it didn't seem like it made any difference. One thing I would suggest if you go with a LS6 valley cover is to have a fresh air inlet on both valve covers for better crankcase ventilation. After I did this the oil I drained out of my catch can has much less combustion blow-by smell.

Here is the "best" standard PCV setup using a LS6 valley cover. The rear driver's side VC port is the worst place. Because of the tilt of the engine and acceleration inertia raw oil gets sucked up.
