So, you're saying I was there the right time of year... I really did enjoy the stays up there. Very beautiful. I would definitely bring my family there for vacation.

 

I deleted the PCV altogether. It's not really required unless you have state inspections (as far as I know). You can vent to atmosphere through a catch can. It's supposed to be better to have the vacuum present in the crankcase on an NA motor, the vacuum is supposed to help seat the rings.

I'll go through and update the links if I can.

 

Yep. And degrease it, then torch the crap out of it to try and burn the oil and carbon type stuff out of it. It welds ok, but like cast... good cast aluminum.

You can ditch it and go catch can only. It's only a suggestion, I (personally) really doubt that the slight bit of vacuum at part throttle really does much in comparison to the pressure on the other side of the rings.

 

Tell me again the benefits. Specifically?

I stated the "purpose", then stated why I think the purpose isn't that big a deal.

The only time the crankcase sees much of a vacuum with a PCV is at idle or deceleration. So during either of those two cases, you aren't making power that would benefit from "more seated" rings. The argument is nil in my opinion.

In an NA motor, under partial load (not idle or decel) the combustion chamber pressures are somewhere around 15 bar *(according to the ol' interweb). That means that if the rings saw the entire vacuum that could be generated at idle, it's only a 7% increase in relative seating pressure. But that can't happen. As soon as you crack the TB, most of vacuum goes away. The harder you are under throttle, the less vacuum the crankcase sees.
At full load, the combustion chamber pressures are upwards of 50 bar. At those pressures, the vacuum at idle is only around 2% of the effective pressure. But again, it doesn't matter because the engine doesn't make vacuum under load (ideally).

This is really all negligible anyway. The PCV only actuates when the TB plate is closed anyway. As soon as it opens, the PCV closes and the crank case blow by is pulled through the front vent in the valve cover through the TB, and into the combustion chamber.

This whole mod is to keep from pulling the crankcase pressure and oil particles that travel with it from running through the intake, TB, and rest of the system.

The couple percentage points of extra relative pressure to help seat the rings at idle will never be noticeable on these engines.



BTW, I just found all the bold, italics buttons....

 

Yep. You could simplify and get rid of that setup altogether and go with an adjustable solenoid, but you'd have to do some research to see what kind of signal or load the AC amplifier can handle. .....So there wasn't a solenoid controlling a diaphragm....

 

You sure could. But in his case, he's still running the factory ECU, so that's out of the question.

And as far as the trigger wheel build, I posted a few pics, but the rest of that mod was kinda done on the fly. I can machine a wheel and oil pump for you, or you could do it (or have it done) yourself.

 

It has to be machined to clear the trigger wheel.

 

Under boost the PCV is closed. Soooo.... It doesn't aid in venting at that point.

You said that, which is why I'm confused. It's true. My deleting the PCV didn't help or hurt the venting of the crankcase. True, it may be undersized, but it's all the engine originally had and all that the 22rte has.

On the stock setup, only one aids in venting at a time (really). I mean technically, now that I think about it... Because of the front vent being in front of the TB, the crankcase will never see any type of serious vacuum.

 

Ah. Good point.
