Rb26 Running Rough As Guts

Hey guys,

Was driving the GTR around the other night and just as I came on boost the hose from the turbo manifold to the intercooler came straight off. I reattached it and clamped it back on but is still running like it wasnt reconnected, I had a look at the pfc hand controller and the air flow graph was all over the place and would eventually just stall

I disconnected the AFM, started the car and it instantly stalled. I reconnected them and tried starting it again, same as before I disconnected them.

Ive had a look at the cooler piping and all seems to look okay, as much as you can see through the bumper vents.

Could there be something wrong with the AAC valve or something a bit more serious?

Going to pull the front bar off and have a better look over the weekend, but any suggestions in the meantime would be a massive help!!

Cheers

An update on the situation...

I took the piping that popped off right off to see if the silicone split and there was no spliting. I shone a torch down to the intercooler inlet piping and to my misfortune there is a BUCKET TON of metal shavings.... Ohhhhh man..... Fml

I was hoping you'd say an intercooler pipe was rubbing and had worn.

one way to find out about the turbos. post a photo if you can take one. Hope your motor is okay

Im taking it down to allsparks performance later in the week to get Frank to go over it and provide me a better indication of what is going on.

Its doing similar stuff to when the first coilpack shit itself, but seeing those shaving really makes me worried. I dont know if.the previous owner had his turbos go and its just residual flakes from when they gave way and have just stuck to the blowby oil in the piping or what it is

Best case scenario, im up for some new coilpacks, worst case... You can imagine

So turns out, no blown turbo, THANK GOD! The "filings" was simply the reflection of the light reflecting off the ripples in the blowby off the silicone piping haha!!

Damien from G6 motorsport had it all day and couldn't figure out what was wrong with it.

He had a look at the spark plugs and they were disgustingly black.. Simply from when the cooler pipe popped off and the mixture in the cylinders not being what the computer was programmed for and fouled out 4 of the 6 plugs. New set of plugs and away she goes, back to normal!

      Mistakes were made, my R34 Story

      By GTSBoy · Posted

      This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.

      J50 clock date suddenly reset to January 1

      By suko · Posted

      The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.

      Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!

      Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.

      Jacks that fit under GTR lips that can reach the subframe?
