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.

      GTR R34 Limp Mode

      By GTSBoy 路 Posted

      Has equal chance of cleaning an AFM and f**king an AFM. I think you can work out what happened. When the Hitachi ECU sees the AFM die and goes into the associated limp mode, then it will start and run just fine, because it ignores the AFM and just runs on idle maps that will do what it needs to get it going. But there is no proper load signal, so that's about all it can do. My suggestion? If you don't want to go full aftermaket ECU, then get some R35 GTR AFM cards and some housings to put them in, in the stock location, and Nistune the ECU. Better to do a good upgrade than just replace shitty 40 year old tech with the same 40 year old tech.

      GTR R34 Limp Mode

      So my car was recently having trouble starting on initial crank, I would need to feather the gas for it to start up but besides that it would start and run fine. So I clicked the idle air control valve (with throttle body cleaner) and cleaned the MAF sensors (with MAF cleaner). The start up issue was fixed and now the car turns over without the assist of the throttle, but the car is in limp mode and wont rev past 2.5k RPM. From what I understand the IACV would not put the car in limp mode, so I am to believe it is the MAF sensors, but it was running fine before and now I cant get it out of limp mode. I cleaned the MAF made sure the o rings were seated properly. Made sure the cables were plugged in properly, the cables also both read the same voltage. Does anybody know why this is or what could be causing this or how to get it out of limp mode?

      Thanks. Yeah I realised that there's no way I'd be able to cover the holes with the filler, it would just fall through. Thanks again @GTSBoy!

      That was the reason I asked. If you were going to be fully bodge spec, then that type of filler is the extreme bodge way to fill a large gap. But seeing as you're going to use glass sheet, I would only use that fibre reinforced filler if there are places that need a "bit more" after you've finished laying in the sheet. Which, ideally, you wouldn't. You might use a blob of it underneath the sheet, if you need to provide some support from under to keep the level of your sheet repair up as high as it needs to be, to minimise the amount of filler you need on top. Even though you're going bodge spec here, using glass instead of metal, the same rules apply wrt not having half inch deep filler on the top of the repair. Thick filler always ends up shitting the bed earlier than thin filler.
