Fuel/oil Smell?

[Xizor]

Ive had my car for probably 6 weeks or so now, and the entire time it has this intermittant fuel/oil smell inside the cabin. It does not seem to matter whether i drive it hard or soft, and the smell is not always there. It does not seem to matter where the aircon is on or not, or if the windows are up or down. Sometimes when you can smell it its stronger than other times. It annoys the shit out of my girlfriend and it is annoying when it happens and surely should not be normal.

The car recently underwent a full service, but i forgot to mention it too them. It did have an oil leak before which seems to have been resolved during the service. But the smell intermitantly continues, just as before.

To be honest, im at a loss. It doesnt happen all the time and i've yet to work out a pattern of what causes it.

hey i have the exact same problem in my r33. It never smelled like fuel in the cabin until i put in a larger fuel pump a few weeks ago. im goin to check mine to see if there are any leaks in my hoses in the boot. im sure its coming from there in mine.

I am pretty sure i have stock fuel pump, but i did have to get a replacement (got a GTR one - stock one was crappy and a bit blocked) fuel filter about 6 or weeks ago. Although to be honest im pretty sure it was happening since before that anyway.

2 weeks ago i had the fuel cap/socket/enclosure thing re-sealed. Its meant to be done as part of the compliance process but that whole procedure is often dodgy so i have learnt. Anyway apparently this can cause a problem of that nature, so i had it re-sealed and left it for a week so it could set properly.

I have been away on holidays so to be honest have not driven the car much, but the problem seems to of died down since having that done. But who knows really...

I dont have a fuel or oil smell but at times I get this methane smell, it reeks like someone farted or exhaust fumes... i can vouch for not letting off in the car... what can cause this?

[Xizor]

Well the gf insists the smell is still occuring, so there we go. I think we are all just farked and need to make sure noone sparks up in the cabin.

33's seem to have a problem with fuel smells when the fuel tank has been overfilled.

You aren't over filling the fuel tank are you?

Perhaps you have a small fuel leak?

While the car is running, pop the bonnet and check around all the fuel lines for any leakage (pointless doing this while the car is turned off, as any small fuel leaks will evaporate before you see them)

Yeh yeah ive got the same problem!! i only picked up my car yesterday, factory stock gtt r34 except catback, everytime i stop, the cabin smells like fuel, not sure whats happening?? from the exhaust?

[nesh]

hey i just purchased a skyline 2 weeks ago and i have noticed the exact same problem and it seems as if its coming from the boot, sometimes it comes out of nowhere sometimes its not there but when i give it, it seems to get stronger and im defenetly not over filling my tank.

[Xizor]

Yeah i've noticed it again the past 2 days, definitely not over filling the tank. Oh well...

Check all your hoses... esp near the fuel filter which is on the left hand side of youe engine...

[gts-4 dreamer]

muhahah

whats sad is if my car is running all you can smell is the exhuast fumes and most unburnt petrol being pissed out my tail pipe from the expensive 600cc side fed injectors in the block with a stock ecu and stock smic,

non-standard 1 piece dump which i thought was just the stocky with some shit sheet metal cover but turns out to be larger dump to my non stock cat, (also NFI what type etc) but it's inlet and outlet both 2.5" to my 2.5" cat back to my rather silent 3" outlet mufler that makes a wheezing sound on full STOCK boost....

i get about 200km's to a tank

oh and my f**kwit couzin decided to redline her and she has had some shite ticking sound in the exhuast since and started rev hunting that night, hasnt rev hunted since, havent noticed the ticking sound cept 1'ce since...

hmm.... f**king give me an ecu and a front mount and some decent head studs, some replacement exhuast manifold studs and accompanying gasket. and i could make some decent power.... probably would get the same mileage to.... f**king car, worse than a women

Yeh, I had a fuel smell. Traced it for ages and found is was worse with the windows down. The seal that holds the new filler cap and filler restrictor neck (installed at compliance) was glued in with what looked like gasket goo. The fuel disintegrated it and the smell would leak out and get sucked into the cabin by a vent at the back and the open windows would draw the smell all the way to the front of the car.

I yanked out the fuel filler neck restrictor and whacked it back in with some sikaflex. Worked a treat. No more smell and now I get a satifying whoooosh whenever I open the petrol cap.

Unfortunatly, when you fix it, the issue sometimes reoccurs. The pressure builds up in the tank when you drive and splash the fuel about. Like when you shake a tin of petrol, the tin expands. This positive pressure probably causes the seal you made to blow again. Mines been going ok for a while. But I keep an eye on it.

The oil smell, well, I don't know. It could be the oil that was leaking out of your engine is still burning off. Or you could be getting a woft of rich burnt fuel from the exhaust. I get something like that every now and then when I give it a squirt.

I had an oil smell in mine, turned out the the rubber seal around the gear stick had perished letting gearbox oil fumes into the cabin.

replaced it with a CV boot from the wreckers, only cost like 15 bucks. no more smell.

or you could just install a short shifter.

might be a possibility
