Rb26dett Blowing Oil Through Ssqv's

[gucio]

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

its normal for after market BOV's to spit abit of oil but how much oil are you talking about?....

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.

that is not a good sign...

[gucio]

Yeah that is what i thought Beer Baron, but i was hoping someone could give me some advise on where it might be coming from

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

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 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.

Its not turbos mate i changed mine still does it.

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?

[_K1NGTR_]

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.

Thanks K1ngtr, will do. Hopefully it doesnt turn out too be bad
