i have oil leaking from the bolt closest to the fire wall on the exhaust manifold. I recently used an easy-out to remove the previous broken bolt and since replacing it with a new one oil has been pissing out.

any one got a clue on what ive done and how to fix it?? any ideas appreciated!

the bolt is definately the right size and in nice and tight. Im unsure whether it had a copper washer as the stud was broken since i had the car. Should there be oil in this area of the engine in the first place?

the bolt that i have used has a washer but does not completely cover the hole on the manifold like the others do. But i am still unsure why there is oil coming out as i think there shouldnt be oil there in the first place. Maybe i have damaged the exhaust gasket but no oil is seaping around the gasket only from the bolt hole.

thanx for your help

there is no oil in the exhaust manifold dude , it must be leaking from somewhere else like rocker cover .theonly thing that comes out of the ex manifold is exhaust so if it was leaking there would be black around it .when u drilled the bolt to install u r easyout did u drill to far in to the head maybe ?if u did that may explain the oil . pull the bolt out and blow compressed air in the hole to see if it goes in to the head if it does thats u r prob , if it doesnt look elsewhere for the oil leak.

as far as i remember that should be a stud in to the head and a stainles nut with a thick washer , the washer is there so the nut can be tightened and cause the hole in the manifold is big so the man is easy to install .people brake these studs cause they do them to tight, u should use a torque rench to do them up and start from the middle and work ur way to the outer nuts otherwise u may warp the manifold .when u undo them u undo the outer ones first and work u r way to the middle .

there was oil leaking from the broken stud before hand thats why i decided to replace the stud, but no were as much as it is now. The rocket cover isnt leaking the oil is deffinately coming through the the manifold hole where the bolt is. I must of drilled into the head or some thing god damn hope its an easy fix for ats

take that bolt out then ,clean all the oil from that area if u dont have compressed air try to fit a tube in the hole and fix it somehow so it doesnt leak ( the tube ) blow or suck at the other end of the tube if air flows u drilled to far into the cil head and oil works its way through the thread ,if thats the case get some locktite put it on the tread of the bolt u are using ( i hope its stainless otherwise u wont be able to get out in say 1 years time ) then screw the bolt back in wait for the locktite to harden say 1 hour and it would probably fix your prob.

when u pull the bolt out put a very thin screwdriver ( thiner then the drill u used ) in the hole if it goes in a long way u drilled to far in .

if thats what the problem is it should work .if u have to buy the locktite get the red one for studs a cant remember the number of hand , just ask for studs and its red not blue .by the way its not cheap either like $20 for a little bottle but u only need a very small amount . i hope it works for u .

    • 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.
    • 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!
    • 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.
