Hi!

I hope I can some quick help in here!

I have an 1994 Cafiro A31 with an RB20DET swap, except for Exhaust and Air Filter standart. I have, especially now where it is cold, very strong exhaust and fuel smell in the car. My wife is pregnant now and that worries me a lot!

The smell is strongest whe I start the car, gets a little bit less when I drive a while. The smell is there wether the heater is turned on or off, means either Air is venting or not venting, smell stays the same!

Anybody any ideas? Need to get it fixed as soon as possible!! Sorry for the bad english

Thanks!

A friend of mine was telling me just last night that the seal in his fuel pump was messed up, and that caused a fuel smell in the cabin.

Might be working checking

I will check the seals, but I thought this problem occurs mostly in station wagons??

It`s defenetly not the fuel pump, everything is dry around there and also no smell..... I will check the seals and the exhaust and come back to you guys if the problem still persists..... Of course also if I solved it!

So far thanks for the input!

Does it sound like youve got an exhaust leak? i.e. open the bonnet and listen.

I get this too, just got my car isnt propperly tuned yet and its running a bit rich...

My money's on exhaust leak.

So, I brought the car to a shop, and indeed, the gasket of the exhaust manifold was worn down and cracked. They fixed it. Also they closed a few holes in the trunk.

But I still got a bad, heavy exhaust smell when the engine is cold. It disappears after a few minutes though. My question now would be. Does the new gasket need time to expand to completely seal the manifold?? The guy from the shop couldn`t understand what I was talking about....

Thanks!

But if it would be the O ring of the fuel pump wouldn`t it be fuel smell?? It`s defenetaly exhaust smell.......

I will bring the car one more time to the shop on wednesday, I will let you know if he`ll find out what it is.

Thanks for all the input!

      From Japan and back to Europe, my sh*tbox R34 GTT

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
