Deleted Egr and charcoal canister. Pcv?

[turbojoe1]

Any different way of pluming the pcv system?

I'm looking To clean up the look and prevent it from sucking oil and contaminating intake charge/fouling plugs?

Any tricks

Thanks Joe

You can eliminate the PCV altogether if you want and run open breathers. 2 low restriction open breathers, one on each valve cover is a good way to go. You will smell some blowby inside the car sometimes, especially if the cowl weatherstrip is missing. But no more oil getting into your intake that's for sure.

Ok. I just was not sure if that was a good idea.

What about ring seal?

Thanks Joe

 

[BEATAV8]

ring seal doesn't care much about whether or not there is a PCV valve present.

 

[turbojoe1]

Ive read that the vacuum help with ring seal, to aid against blow by. But that was on a chevy truck forum

Thanks Joe

A vacuum pump is a different story as it works very much differently compared to a PCV. A PCV only works at idle and at light throttle cruising or deceleration when there is some intake manifold vacuum.

A vacuum pump works its magic at wide open throttle full load, pulling a strong vacuum on the crankcase.

Ok thanks bud, i,ll delete them.

Thanks Joe

Steve and I love this subject.

The blowby vapors that end up in an engine's crankcase contain moisture as well as combustion byproducts and unburned fuel vapors. The vapors must be removed to prevent oil contamination that leads to sludge formation. The positive crankcase ventilation (PCV) system siphons these vapors from the crankcase and routes them into the intake manifold so they can be reburned in the engine. Valve cover breathers alone will not do the job of a pvc.

A vacuum pump would work. You just have to regulate the amount of vacuum. Too much is not good.

The vapor canister can be moved down on the frame by the steering box. Why remove it?

EGR is the only thing I would block.

I see.

I removed and sold the vapor canister, cause why not. Its not needed, the car is old enough that i don't have to worry about echeck.
Plus im removing all the un nessasarys for racing and a cleaned up engine compartment.

Thanks Joe

Is there a specific electric pump that you recommend?

What did you do with the end of the line that went to canister?

Here is another great idea from one of our member Pronto who installed a oil catch can http://www.turbobuick.com/forums/threads/installed-an-oil-catch-can-today.392886/

 

[turbojoe1]

I like the idea of the little one meant for an air comp, can just tuck it on back of one of the heads. I think i'll try this route

Thanks Joe

You are correct in your statement, and to add to that the factory did provide a means to evacuate combustion gasses/vapors, but one of the first things we do is disable it?

The stock pass side valve cover has a pipe/hose connected to the turbo inlet to allow fumes to be pulled into the engine.

The turbo inlet is a low pressure vacuum area which will draw crankcase vapors into the engine. The oil fill on the driver side valve cover is actually sealed so the fumes can all be evacuated and not have positive pressure in the engine that will actually blow oil out the breathers.

The vapors pulled out by the factory system is removed as we make mods and increase the boost, but the vapors leave an oil film deposit in the intercooler and intake track.

If we put breathers on the VC's, and do not trap or direct to vapors/oil to a container, oil will just blow out into the engine compartment.
