Hi all,

Hope you can help.

I have an R33 series 2 GTS-T that is chewing through oil, like over 5L in the last 2000km. I use Valvoline full syn, the cars always run rich but never used oil like this.

There's no leaks under the car, the only oil I can find in the engine bay is around the rocker cover.

The car unfortunately sat in my driveway for 3 years and didn't do much, so I'm guessing seals somewhere but just don't know where a good place to start looking would be.

Had a few upgrades though, high flowed turbo, front mount, BOV, exhaust etc

Thanks so much

I'm guessing it's blowing a lot of smoke?

Yep, it its not on the floor, its probably gone out the exhaust. Burnt oil smoke is a bluey/whitety colour.

When mad says check coolant, you're looking to see if it has oil in it.

It's always run a bit smokey when giving it a bit of a hit, but its black not blue or white.

Someone was telling me about some kinda oil flush stuff to put through it, I've always run 98 octane but I'm thinking there must be a bit of carbon built up through the pipes.

The turbo spools up fine, it never overheats has always run cool, doesn't use coolant really.

If the piston rings are gone can that lead to any engine damage?

I had same issue... First thing I did, check coolant and oil for mixture (if that's the case usually means cylinder head gasket)... If that's not the issue monitor the exhaust to find out exactly when it blows smoke (eg. Cold starts, cruising down a hill, or on hard acceleration).

Once you've done that you could probably post your results and we'll help ya some more ;)

PS: from what I've heard if its your piston rings the thing just blows white smoke constantly and unbearably... I blew the rear seal on my turbo and everything was running fine - it would just burn oil in the mornings!

Hi guys recently got a r33 gtst has some mods bigger turbo bov cat back exhaust boost controller turbo timer etc, when I got it it blew smoke but only when the turbo comes on boost, other then that when idling is fine but runs rough, I've researched a lot about it and ive taken my intake all off this morning and there's oil every where through it, and I mean everywhere intercooler all the piping etc, so I'm cleaning all that out and have a me manic coming to do a comp test today but there's no oil and where but on the turbo and in the piping, could a blown turbo seal be the cause of this or is it something major? I've read the pcv valve and also the valve stem seals could be the cause but why is there oil in my intake? Any opinions/ advice would be much appreciated

I also checked the radiator there's no oil in there, there's no sludge under the oil cap or a milky colour, the smoke it popes out on boost is white and can smell the oil burning. I've been told it's running 14 psi aince the new turbo was fitted that seems a bit high for not even a year old turbo

Haven't you already started a thread?

Anyway, this time you mentioned bov, which I assume is an atmosphere one. Other thread you mentioned 'lumpy cam idle' which can be caused by the bov being partly open at idle and drawing in unmetered air.

Regardless, put stock bov back on.

Your oil everywhere could be due to turbo seals, or excessive blowby due to piston ring wear. If the oil is in the inlet to the turbo it is blowby, if only in the turbo outlet it's the turbo seal.

Valve stem seals don't get oil into the inlet pipework.

You could try adding a catch can, but I wouldn't expect a miracle.

And I don't have the stock bov, and I haven't had a chance to pull the rest of the pipework off just intercooler and pipe work to the turbo, and yea it doesn't sound excactlt like a lumpy cam but I know it doesn't sound how it's suppose too, also the bov seems to have oil coming out of it and there's a bit of oil over the engine as though it sprays everywhere from the bov?

Get a stock bov on there ASAP.

But that's probably the least of your concerns of its spraying that much oil

Lol - I broke a ring land and now my car sounds like a lumpy 1000hp beast and sprays oil all over my engine bay...

Okay guys I've cleaned out the intake of all the oil and I've disconnected the HKS bov, smoke has thinned right out to a shuttle black puff after you rev it but no white smoke, seems to be a rattle near the turbo but the idle is better and smoke is gone. Any thoughts ?

Not surprising it idles better without the atmo bov.

Best option is to get a stock bov and use that,isn't that obvious? ;)

Did you do the comp test?

Rattle near turbo could be loose heat shield.

Oh . I will stop guessing what your issues are.

If you want to give us half a chance at helping you post some pics of engine bay.

Why would a custom pod mean you don't have a heat shield on your turbo or manifold?

Yes, ffs, fit the stock bov. It will mean it won't make annoying hectic noises, or make your car idle like shit, or spray oil all over engine bay due to massive blowby issues you seem to have, and you won't get a defect.

I haven't suggested it to you numerous times because it is pointless and won't help.

      Never ending fuel pump drama

      By Murray_Calavera · Posted

      The price isn't the issue, it's how hard my fuel pump is to remove now. I fabricated a custom bracket so my pump sits on the very bottom of the tank (I ran the tank down to 5L remaining to test it, works well). But it is a fkn NIGHTMARE to get the pump down into the tank now =/ words can't describe how much I hate fighting with the fuel pump/hanger now. The other issue is reliability, I'm driving down for WTA in a couple of months, I'd be less then impressed if I was half way to Sydney from Brisbane and my pump fails again =/ The other issue I had was my car battery was slowly failing, with low battery voltage my fuel pump couldn't keep up with what the reg was asking from it. I've replaced the battery and my fuel pressure is back to being perfect.  As for the low voltage situation that killed my previous battery, I've got a 150amp alternator sitting on my desk waiting to go in. Fingers crossed that will sort that issue.

      OK so I just bidded $500 on an R33 GTS4 that no one seems to want. Waiting on a call from the agent to see if I won. 32 GTS4 is for sale. I can't deal with the temptation to mod it.

      Might be there for work later in the year. Wouldn't mind catching up with you fellas - can't have too many beers, but will consume copious amounts of takoyaki while executing an asian squat on the side of the road while you blokes sort out your hangovers.

      I know one example is a anecdote not data, but I'm running the same Aeroflow 525 at full voltage through a regular relay, and while I've had other fuel problems including melting the factory fuel hat, the pump itself has been fine for years. Of course, they aren't *that* expensive these days, you could swap in a new one and see if the issue is resolve. I think you had a previous thread about fuel problems, have you been monitoring and logging fuel pressure? Is there anything voltage related (for example does the voltage go up when the pressure goes down)
