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!

      The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
