Hey guys I noticed quite a bit of oil residue around the (aftermarket) blow off valve. So I opened up the intake piping and found a shitload of oil + water in that murky brown looking shit you get from a blown head gasket. Motor hasn't lost much oil at all infact after driving 1,100 Kms the dipstick is only slightly down from the full mark; I wish I knew how many Kms are on the motor but it seems to be in very good condition.

I bought a replacement turbo from Skyline Spares in Wetherill park. Swapped it over, and my problem is still there possibly worse. The shaft on the new turbo had a small amount of play, but made a slight noise when spun and it would just stop rather than spinning for ages. I was told by the guy who served me this is because they use journal bearings not ball bearings and there obviously wasn't any oil in it.

Was I sold a dodgey turbo? or did I have a different problem to begin with

Thanks

Sorry I forgot to mention that I was told that it was likely that the seals on the turbo were blown causing oil and water to leak into the intake. Is this correct?

I drained the coolant when I swapped the turbo so I didn't end up checking (there'd be no point in checking the new fluid). Theres no water in the oil though

its more than likely from blow by. do a comp and leakdown test. and install a good catch can so the intake pipe doesnt suck the oil from the head and fill the cooler pipes up.

obviously also clean the piping out

seconded.

if the 2nd turbo was making better boost, will also push more oil out of a worn engine.

If hs turbo seals were completely blown he could get water and oil in the pipe work.

There is no water seal in the turbo, the water runs around the core, so there's no way a turbo could leak water internally.

Is this true? I need to know as I plan to take the turbo off and back to the wrecker today

edit: I still Have water + oil in the intake piping and coming out of the BoV.

WHERE IS THE DAMN WATER COMING FROM!!!?!?

Coolant is fine, no oil there.

Oil is fine, no water there (hasn't been changed for 4000 kms)

Is a comp test necessary? low compression can't be the cause of water in the intake

When I pulled the first turbo off there was oil sitting in the compressor housing.

edit: I think I need a catch can, previous owner said he removed an ugly looking catch can from the pre-previous owner.

But what about this damn water??

Edited by Blackkers

See how that picture is taken from one of the pipe after the intercooler (i.e between intercooler to throttle body)... Have you inspected the intercooler and or any pipes directly after the turbo to see if there is any build up there?

water is fairly common in catch cans etc. depends on the climate where u are etc.

i have seen catch cans be filled with water from condensation.

for now forget about the water part and treat it as pure oil. diagnose fron there

But what about this damn water??

Combustion gases are full of water. Water condenses once it cools down. So worn rings (low compression) let a lot of combustion gases past into the crankcase which then gets into the turbo inlet.

Okay guys tomorrow morning I've booked a compression test. If the motor is fine (which I suspect it is) then I am taking my ORIGINAL turbo to precision turbos out in Wetherill park to get hi-flowed; I was told $1300, has anyone got experience with these guys? does anyone recommend another place for hi-flow with better service or a more competitive price?

I'll search the forums now but I'm wondering if any of you have experience with this.

Thanks

I'd postpone the highflow until you're completely confident you've addressed the current issue. Remember even if the compression test comes back ok, you still have a problem to fix.

Also, dont forget you may need injectors/AFM/programmable ECU and tune = $$$$

    • LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.
    • I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy  
    • If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.
    • Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.
    • Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
