Hi Guys

I have a major problem here, there is oil coming out of my SSQV's. It only started happening recently about 2 weeks ago. I dont have a catch can and the original piping is still inplace meaning that the pressure from the cam covers still goes into the intake.

The car is a 1992 GTR with about 130 XXXkm's on it, it has been modified with 2860 -5, power fc D-jetro, Sard 700cc, Bosch 040, N1 oil pump. The parts have only recently been put on around 110 XXXkm's.

Does anyone have an idea as to way this is happening?

I have come up with a few idea's of my own which are: oil pumps pressure release valve is stuck, blown a cylinder or blown a seal on the intake side of one of my turbos.

Cheers

i have some oil marks on the trumpets of my atmo bov

been there since i bought the car and hasnt caused any problems.

id guess its just excess oil finding the closest way out. ive been told a catch can can fix the problem.

i had a catch can recirculating into the intake for about a year, just pulled all my intake piping off and intercooler to find it all lathed in oil.

Cleaned them all up and bam car feels great, clean pipes and intercooler really make a difference to intake temps.

So i have removed the hose from the catch can to the intake and its just venting into the atmo which is illegal but the way ive done it looks like its going into the sump.

Well the oil that is coming out is being sprayed onto the front of the front bumber and down the side of the front bumber.

The thing that worries me is that there was no oil coming out when i put the SSQV's on in the first place but after some time it just started to blow oil.

Well it probably wouldnt be the pressure release valve in the pump, otherwise youd have huge oil pressure and wouldve popped an oil seal in the engine out by now.

Were the -5s new? If in bad condition could be the seals like you said, but probably not.

Check the pipe that goes from the P/S rocker cover to the intake pipe, see how much oils in there. If theres heaps, could be a ringland or something.

Check compression.

Typical scenario with old-modified RBs :D

Aside from what others have said....it also depends on how hard you were pushing the car....street or track. The first time I went to Sandown in the R without a catch can I had oil leaving the BOVs and spitting onto my front right tyre....not great for grip :D Fitted a catch can, cleaned the intake and the oil never reappeared.

mate i had the same problem before my motor gave way would love to know what the problem is to!!!

also i have twin HKS SSQ's to mine was spraying on to the back of my front bar then drips man i would suggest to take it to someone asap man my oil pump was f*ked or something not 100% man

Fit a catch can, a temp home made one or an ebay special that doesn't vent back to intake and it will tell you one way or the other if its turbos or not.

If the oil stops coming out the BOV's and the can fills up then its coming out the breathers. Vice-versa and its the turbos.

I also noticed my catch an would fill up when driving hard. With the rb's issue with oil pooling in the head and the cam covers sitting on an angle, every time you corner hard around a right hander it must just spew it out very quickly.

Femno - the turbo's are brand new also will do a comp test when i get home, i hope its not a ring land :)

Ant97GTR - Well it started happening after a run at the drags, luckly i am not getting oil on the tire as yet

K1ngtr - the oil pump is brand new

fatgts-r - yeah just brought a catch can will be fitting it when i get home, i hope this tells me where to start looking.

I was also thinking of fitting the trust oil restrictor (the one that sits in the head) what do you guys think? will this help my situation?

just take it somewhere man i left it and my motor went... cuz the oil leaked out slowly and caused major damage as long as you know the problem check your oil levels and do something aobut it you should be fine.

    • That was the first session so not a lot to take from the day. It was low 20s ambient and the coolant had got to 110 (and obviously had some pressure!) so that still needs to be addressed. I haven't downloaded the data yet but will. I had refilled the auto trans with Redline DT6 because it claimed the best viscosity I could find at 100o. It wasn't really long enough to get a good feel for that; while the trans got to 100o in the session it still wasn't shifting crisply as I hoped. I think I'll try a few more sessions before judging. No steering motor overheat but I'd hope not in only 1 session! But finally the suspension; it was night and day over the standard stuff and the car was a couple of seconds quicker on the same crappy tyres, which is a huge difference. I'll stick with that and get some sway bars and a mechanical diff sorted too and see how that all goes together
    • I guess it’s partially a compromise of how my car is used, wanting to be able to switch from drift to grip with track side on-car adjustment. Also partially with the way the knuckles are set there is more static camber but less dynamic camber gain. 
    • OK, so update from the track day on Friday It was a classic "an unfortunate series of events'. There were a few cars around and when i checked my mirror coming out of the fish hook I notice some smoke from the rear of mine. Looked again and it was getting much worse, I figured I'd blown a turbo or something to got off it and pulled off the racing line. However.... since it is a left hairpin into a right kink, I was on the inside of the next corner. There was a car passing me on the left and a big drop off over the ripple strip on the right......and someone had knocked the witch's hat that was on the apex about 1m onto the track. So, between those 3, I decided to mow down the cone and not damage my car/the other car. Right choice, but surprising result.  The car decided the cone was a small pedestrian so it blew the rear bonnet hinges up to protect their head in the upcoming person to car impact....I didn't see that coming and like an airbag deployment it happened super fast. Straight into the pits from there, everything was driving fine but it became clear it was a coolant leak not smoke, it was billowing up onto the windscreen. Onto the trailer and home. I'll do a separate thread about the repair (once I work out what it is ), but the immediate problem was the bonnet wouldn't open because the front was pinched onto the front bar and would not release. Ultimately we unbolted the hinge from the bonnet, pulled it back a little and it released from the front OK. "There's your problem", the top radiator hose had popped off at the radiator.
    • Yeah that looks like great caster, but I'd suggest trying less front camber some time and seeing if it helps with braking without reducing mid corner speed too much
    • I ended up setting the rear 5mm higher than normal to give some clearance.  My plan is to run the least camber I can in the rear which I think with the extra width is going to need to be -1.75 to -2.00° just to get clearance.  Guards have been rolled and pulled as much as they can/I would be wanting to.  front has the Acostal knuckle with the KPI change and the drop etc. So should be okay with the existing settings I have run with AR1s etc Front: Toe total -2mm(1mm out each side) Caster +7.5° Camber -3.8° Ackerman +15°
