Blocking Rb25Det Pcv

[Trozzle]

Yes, only an issue when there is a device metering the incoming air.

Do you have a breather from your crank case to the catch can? IMO this one is pretty critical if blocking the PCV valve and running at atmo system.

I don't have that breather if the question was for me.

Though yes, I can understand that it will have to BLOW the gasses through my proposed system rather than them being sucked out when the plenum is under vacuum. Not ideal, though will still work.

My ultimate reason for wanting to remove the system is that the fitting on the rocker cover is actually a suspect as well - the whole thing has a bit of play in it. Meh, whatever.

Cheers for the input though guys, at least I know I can give blocking it off a shot anyway without worrying about my crank case becoming a pressure bomb.

There are passages in the sides of the block that are for blowby gasses to equalise with the head. The PCV valve is designed to draw these gasses out when the pressure in there is higher than in the intake manifold (i.e. under vacuum).

I'm at work and trying to focus on things completely not car related so my brain is struggling

IN the R32 Engine manual there is schematic of the blowby gas system, might help explain it a little

Was mainly for gotRICE but she'll be right

It won't ever become a pressure bomb, the worst it could do it pump a heap of oil out the exhaust either via the valve stem seals or the turbo.

I suppose I'll even notice the oil pressure go up on the stock gauge should this occur

lol no, you won't. You should notice the big clouds of blue smoke out the back though

Years ago I had a Gemini that had a block filter thingy coming from the rocker cover to the air filter. I floored it at the lights and as the revs got up in second or 3rd (cant remember now, was a long time ago) the dipstick popped out and poured out all over the engine bay and the exhaust. Clouds of smoke everywhere and the guy I was dragging was grinning his head off.

I wanna set up a Direct-Dump-Pipe-Oil-Injection system....would be tops for traffic light drags!

Like a tank?
