R33 Gts-T Catch Can Issues! Need Urgent Advice!

Hey guys, so I got myself a gtst and joined the team. The engine has had a bit of work done to it. It's running a Garrett M24 and I have some serious pressure issues with the catch can. I have asked a few local mechanics and have gotten different responses.

From - its rooted to its fine it's just not tuned correctly.

One guy basically screamed at me firmly telling me "no engine should have blow by" yet my mate who is the PDM at Toyota/Nissan told me even brand new cars do it which even is backed up on what I have read online. He further went on to show me his turbo hilux, that thing chugged like a steam train from the oil filler. He placed the oil cap over the top and the damn thing started dancing over the rocket cover.

The car doesn't blow any smoke except occasionally a very brief puff when changing gears (first drive of day) there was water in the oil but minimal amounts. I have confirmation the car has only done 1000km in the last 18 months. My mate from Toyota said that he would expect a car sitting that long to have that amount of water in it anyway (condensation) considering the doozy of the problem it has. I had a compression test done and it's a fairly even 120 across the board. However when the car is kicked in the guts oil splatters out of the catch can. I have been told - rebuild it! Suspected ring lans. However when I decided to start pulling the engine out this weekend we found the boost controller had a blown fuse and here is where I'd LOVE the advice, seems like the catch can system is plumbed wrong. (please remember I am a complete noob with these) from what we are assuming, is the Pcv tube isn't connected to the catch can rather it is plumbed back into the boost side of the intake. I will post pics soon as I can.

We are under the assumption that the Pcv is trying to boost 20psi through the top end of the engine and going straight into the tubes that run from the rocket cover into the catch can and blasting it out the filter on the top. When the valve is connected the filter on the catch can blows bubbles when idling, yet when u disconnect it, it stop. Any help much appreciated!!

The PVC is connected to the Plenum, around about where your cut and shut throttle body is. So if you want to connect it as stock, your going to need to tap a nipple into the plenum. As it works under vac conditions.

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Hooley Dooley these things have some history! If i sell them they will need a certificate of providence to prove they have been in the hands of verified RB20 royalty! They have been stored in a plastic tub, away from sunlight and moisture. They are in mint condition. And they will stay that way, as i have sprung the money for a set of shockworks coilovers. I'm just working on getting them in at the moment, after rebushing the rear of the car, and while the subframe was out i welded in the GKtech reinforcement bracing as well.  They will get a workout at Ararat King of The Hill in November. I ran 48s on the short course there a few months ago, and i am hoping with new bushes and shocks in the rear i can launch a bit harder. There was a fair bit of axle tramp when i tried too hard off the line. a few of the corners had dips mid way which also made the car feel a bit unsettled, hopefully this will help there too.

      remote oil cooler hose size, 8,10 or an12?

      Food for thought, the stock oil filter thread is a 3/4-16 UNF, which has an ID of about 10 to 12mm (according to ChatGPT lol). Now compare than to an 10AN, which has an ID of about 14mm (Raceworks is 14.2mm, Speed flow is 14.27mm).

      Yep, totally get that. However hooking in for Generator back up is only a few hundred bucks for the wiring. You could put a couple of those in (for different circuits explicitly) and run a couple of baby generators. Bonus, you can balance them across different circuits, and now have backups in your backup. I'm looking at buying places that won't even have water etc, and I don't mind the idea of getting off the electric grid either, even with everything you've said. This country already has enough power outages that even the mains grid isn't that reliable anymore. I do agree though on spending a bit more to get better gear, and to add some extra redundancy in to the system too.

      You can set hard reserves on your battery system, and it can't be discharged past that.

      That sounds like an excellent idea. But total self-sufficiency means exactly that. You have no-one else to blame when your system faults out and you have no power for a week or two while it gets fixed. You'd have to go the whole hog and get a diesel genny and all the switchover gear, to get you through such times. And, despite the fact that over 20 years, my system has been pretty reliable**, I have seen so many inverter explosions (or less dramatic deaths), panel and roof JB fires, and so on, over that time, to know that the stuff is the same as any other bulk Chinese manufactured stuff. The failure rate is well above zero - both on the equipment and on behalf of the meth addled installation labour force. And then..... warranty and means of redress against the supplier you bought the gear from. Best I can tell is that only a handful of solar companies are still around within 5 years of starting their advertising pitch. They disappear and phoenix like crazy. So, as per 1st paragraph, I suspect the only way to is go balls deep and spend maybe 2-3 times as much as you might think, so that you have every base covered. Plus, know and understand your gear intimately, so you can diagnose problems, sort them out yourself, etc, etc. Plus, probably have to consider upgrading various parts as the years pass, to maintain compatibility with newer stuff, performance and reliability, etc, etc. Whereas, remaining attached to the grid has an ongoing cost that keeps going up even if you use bugger all power from it. But it does provide the fallback in case of the worst case with your own gear. You either pay up front or as you go, I suspect.
