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.

    • It really depends on your setup. Mine is 'accidently' more suited to revving higher. bigger cams, turbo etc. Plus my super long first takes donkey years to come onto boost, so if it will move my power band to the right, maybe i'll pass on this. i have a G45-1500 going on there soon which I suspect might make it more of a fat pig.
    • Yeah good call, I will endeavour to tuck that down when I rewrap the looms it’s pushed up by
    • Good work. I will say, this line circled however, will potentially pool with oil, as it's going from high, to low, to high, before heading downwards.
    • Yeah, thumbsup from me. The distant shot of the bay just looks same-same as before.
    • Dad had a court case drag out with them from 1998 to 2004. He was in a not at fault accident, NRMA were the ones who covered the other person. They tried to blame his neck injuries on the fact he'd had an injury in 1981 on his extreme lower back where he slipped a single disc right near the bottom. Had been all cleared from that injury for years. This accident destroyed his shoulder, and f**ked a heap of discs in his neck, and he still has major problems with it to this day. Sarah's sister while on her L plates had a small Suzuki Alto, she had stopped to give way to an ambulance, and someone changed lanes behind her because there lane was also slowing, and rear ended her at 80km/h. (She had been stopped for a few seconds already too!). Car was completely f**kED. NRMA sent the vehicle around to 3 different workshops as they kept claiming "We believe it can be repaired, and not written off, we just need to find the correct workshop". It took 3 months, and a lot of arguing before they'd concede and wrote it and paid out. About two years later her sister had a Lancer, someone pulled out of a stop sign without stopping (in an 80 zone). Her sister swerved, hit the front of the other persons car (Instead of dead t-boning the drivers door), which ramped her Lancer, and made it roll multiple times down the road. It hit every panel on the way through. Her sister had slid her self out of the car, and remembers the ambos walking to the accident (They'd been sitting at a set of lights just down the road and witnessed it) and they were saying "Well, this ones going to be a fatality, no way you can walk away from that". Well, she did. And then NRMA sent two assessors out to look at the car, both of which wrote it off. They tried to send another assessor out, except a HUGE uproar was raised, and they FINALLY paid it out. That was on a car, that had damage to EVERY panel, you could see from 100m away the whole car was also twisted, roof bowed etc. Nah, we'll try get out of needing to payout on a $10,000 car... Her sister ended up with major shoulder reconstructive surgery being required, and was permanently limited in her ability to do her job as a nurse after that, as she can't (And was told before surgery too this would be guaranteed to happen) regain full strength in that shoulder. However, there was no choice to not have it, as she could barely use her arm, which was her dominant one, and was in near constant major pain. (And she's the type of person that would try and walk off a broken leg!) NRMA did the biggest run around on the personal injury side too for about 18 months, even to the point of trying to put 100% blame of the accident on Sarah's sister, even though the other driver admitted she didn't look, and didn't stop, and was charged by the police. Sarah used to have a Barina insured with them. It was a policy setup, paid all 12 months in advance. At the end of the 12 months, Sarah was living with me, I reviewed the renewal, it clearly stated "If you do nothing, your policy will cease on XYZ date". We did nothing, as we moved her insurance in with all of mine and I was with Shannons. We find out 10 months later, NRMA decided, because he DAD had a car insurance policy at the same address as what Sarah's mailing address was (Garaged address had been changed), that they'd put Sarah's (What should have been non existent policy) onto her Dad's month to month charges on his credit card. We had to jump through hoops, to get a refund. They didn't care that we actually found the letter that said "If you do nothing, your policy will cease" they made us prove we had NON COMPULSORY insurance else where before they'd issue the refund, and after they agreed to the refund, it still took another 6 weeks and 3 more phone calls for them to actually process it. They also had two insurance claims from storm damage, and they were an absolute cluster to get resolved as well (one vehicle, one house). Some how, up until about 3 years ago, her parents were still loyal to NRMA too, and we were like "How the hell are you so loyal to staying with them, when other places are so much cheaper, and they've f**ked you over every time you've ever had to make a claim?"
