i didnt think you needed the filter on there for the plumb back just the atmo? and no that doesnt look like the plumb back to me.

more like the one sydneykid shows.

ill take a pic off mine and post it up tomorow.

omg no, that is wrong.

You DO NOT need to plumb your catch can tank to the induction of your turbo. Block that one up...

how come that is wrong? i can't tell from the pics, but is the pcv side capped?

why is it bad to pull the air through your catch can to the induction of the turbo? the catch can in theory will catch all the oil under boost, which is what you want, no?

the setup looks ok to me..

EDIT: nevermind, just looked at the 2nd pic and noticed your catch can is open to the atmosphere. thats not gonna work cuz your turbo will suck in extra unmetered air through that breather filter. take the hose going back to your turbo inlet and put it on the other valve cover. then cap the turbo side and the pcv side.

It is certainly at least a 50% plumb back design. It could be a 100% plumb back design, but I can't see RHS cam cover to tell what is going on on that side.

The filter on the catch can is of course redundant in a 50% plumb back application.

:D cheers :cheers:

legally your supposed to have it plumbed back into your intake...however who abides the road laws anyway. Just go from both covers to the can and block off to your intake and the top release which you are using atm.

You probably want to remove the kink in the return to the intake before you block the filter off though.

When the pcv shuts under boost all the vapour will be pushed/sucked out by the one hose anyway, it's pointless running a hose from each rocker.

I'd maintain the current setup and be blocking the filter for a few of reasons, 1 it's an obvious defect, 2 i don't particularly like the smell of oil vapour, 3 if you maintain the line to the inlet then the filter is redundant.

      Old Son, did you re-use the Holden ABS in the new shell or try a different module?

      Another little story of weird shit happening

      By GTSBoy · Posted

      Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.

      Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up

      Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️

      Looking for a part number for this part here

      By dbm7 · Posted

      Did some FASTing ...got the impression that the actual part# was a moot point ; seems all of these hardlines for coolant are discontinued/NLA... like, I take it you're after the hardline that bolts onto to the manifold...that's NLA according to amayama & nengun .... ...just to clear up some confusion, they typically mounted the AAC valve to the intake manifold somewhere near a coolant passage, so the body of the valve heats up & holds it open when engine's up to temp - no coolant flows through the valve, it's a mechanical, thermal connection.
