Wtf Is Going On? (Oil Leak)(Pics)

Ok so I drive my car only on weekends. Haven't had much problems apart from a slight leaking power steering pump which was recently fitted by a popular garage in the uk. Anyway as I got home last night, reversing in to the garage I notice a trail of oil, now I'm thinking wtf. Look under the car as it's running and it's dripping oil. Turn it off. Have a gander in the engine bay to see how what's wrong and can't see anything. Did hear it was making a weird gurgling noise coming from the radiator pipe.

Today since I had time to inspect, I jacked up the front and it's coming from the driver side. It's not the cam half moon seals as I got that leak sorted last year and the area looks bone dry. It's not the dip stick as that fits in firm and wasn't even sticking out. Btw it's now reading low on the dip stick. I do have an oil filter relocation kit fitted.

Here are pics I've managed to take today:

You can see oil dripping alongside the power steering rack. Can also see a drop of oil on the oil filter relocation piping from the engine. Haven't started the car since yesterday.

You can see that it's also leaking on to the subframe. The passenger side was fine.

As I was laying on the floor under the car, contemplating my existence and wtf is wrong with the car now I noticed drops of oil coolant forming on the bell housing and progressively getting worse, probably since the car was jacked from the front and not level. I then decided to drop the front down and call it a day.

So now I'm trying to narrow down the leak. Rear main oil seal? Headgasket? Bearing in mind that this seemed to happen all of a sudden. What's the cost I'm looking at? Will order some more oil. Thinking about getting it trucked to a garage on weekend. Hold me guys I'm not gonna make it...

Run your hand under the oil sandwich plate & see if there is oil there. We have an oil cooler, and an o-ring on one of the plugs in the sandwich plate (the ones you remove to fit a pressure or temp sensor) had broken. The oil ended up as far back as the middle of the car.

Bear in mind that (unless you reverse really fast) the oil will go backwards as you drive, so look for the forward-most point with oil on it & your leak will probably be somewhere close by.

Its wet around the sandwich plate so looks to be the kit that is leaking. Leaking on to front diff then dripping on to front subframe.

The only way I can see is to take off the plenum. Easy task?

Sorry - no idea on a GTR, ours is a GTST and while access is tight it was easy enough without removing anything else.

curious, what's that garden hose coming from the front to the back?

I have a catch tank that vents to atmosphere. To stop the fumes going back in to the cabin I connected the pipe to the catch tank all the way to the rear near the exhaust so I don't have to put up with the smell. Works good.

      Recomended Coolant For Gt T R34

      By silviaz · Posted

      What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.

      R34 GTR running rich and noisy turbo coincidence

      Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!

      R34 4 door side skirt identification

      By Rezz · Posted

      No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.

      Welcome mate. Any pics? Even with a DE I'd be well happy if I had that as a 1st car.
