Hi all, I'm kinda scratching my head a bit here ...
Yesterday whilst driving I noticed a strong smell of petrol in the car.
I immediately stopped and switched off the engine. When I opened the
bonnet there was a pool of petrol in one of the exhaust manifold valleys
(between cylinders 5 & 6).
Starting the engine I could see a steady drip of petrol coming from the
fuel line that runs just above this point. There is a short length of
flexible tubing held on with two jubilee clips and although they didn't
appear to be loose I did manage to get one to tighten 1/6th of a turn.
The leaking stopped and I soaked up the residue from the manifold.
After a short while the smell went away from the cabin and I thought
that was it ... until this morning when the smell came back. This time
though I can't see any evidence of a leak, but there is a definite smell
of petrol under the bonnet.
Has anyone else come across this, or have any suggestions as to where to
start looking?

The problem is with old fuel lines. They start to "sweat" petrol, but they
look good as new because they the moisture makes them look black. I had
exactly the same problem. If you feel them with your fingers you will see
that they are moist.
Replacing all the fuel lines solved the problem.
Cheers.

I had a similar situation develop when the fuel pressure regulator failed on
my E30.
The fuel pressure more than doubled so any places with marginal sealing
started leaking.
First it leaked from the hose connecting to the injector manifold. After I
tightened that clamp it started leaking from the hose connecting to the
filter. After the third leak appeared in two days, I got the message and
checked the pressure. Another symtom was that the idle got pretty rough.

Thank you for your concern, Jim. Likewise I appreciate a quick fix might
be beneficial ... except for the wife who has just upped my life
insurance  )

That's no reason to be suspicious.
However, if she hands you a box of matches to help you find the leak, then
you should be worried. >> Stay informed about: 1992 730 - Smell of petrol |

Yeah, I'd better watch out for her smoking near the car when I'm heads
down in the engine bay sniffing for fumes too )

Jack,
Funny you should mention the regulator I've been wondering about that. I
was trying to decide why it would happen just the once and some sort of
temporary blockage (e.g. the regulator stuck shut) seamed a possibility.
Also I remember that the idle was a bit rough when I had the leak.
There's an air hose connected to the top of the regulator which
disappears down a hole in the inlet manifold casting. I haven't tracked
it yet but I guess it connects to the manifold somewhere so that fuel is
only circulated when the engine is running.
There is a short flexible fuel hose between the regulator and the solid
return pipe which sometimes shows evidence of the fuel inside pulsing
and at other times looks like the fuel must be flowing smoothly. Any
idea which is correct?
Looks like another job for Saturday afternoon 
Thanks for your help.

Hi, total newbie here, not only to the site but to BMW's in general (I just googled "smell of petrol on starting" and this is where I ended up, to be honest). The thing is I am currently test-driving a J-reg 316i for a month - the seller's a neighbour of mine, asking £1500 - and have noticed just the same problem. Do you any of you have any advice to someone who has precious little idea what goes on under the bonnet (the shame of it!) as to whether this is pricey to have sorted at a garage? I defer to your greater wisdom... >> Stay informed about: 1992 730 - Smell of petrol |

I had a similar problem on a 91 318i, I had it back to the dealers on 2 seperate occasions and they couldn't find anything. I changed the hose's mentioned earlier. In the end a friend of mine found out where it was leaking from, the "o" ring seals on one of the injectors. They are hidden away under the intake manifold on top of the engine. The replacement parts were quite cheap ("o" ring seals) and the job was done by my friend in about 1 hour. I have never smelt fuel since. >> Stay informed about: 1992 730 - Smell of petrol |

Hi.
I am new to this newsgroup.
I've onwed (and still own, amazingly) my first BMW 318i E36 1993 model since
2001.
My car used to also emit the petrol smell. Initially, I was a little
worried, as it was quite strong when the car was initially started. Of
course, at the same time, my car had damaged rockers, camshaft, and tappets
due to infrequent oil changes.
I have recently had the rockers, camshaft, and tappets replaced by my
trustworthy mechanic, and now I do not smell any petrol.
I will confess that the annoying tapping noise that could have been
considered noise pollution was the primary reason for taking my car in for
the repair.
Kind Regards,
--

Thanks Jason – useful to know. In my case the tapping isn't that loud but the smell of petrol can make my eyes water at times! Pollution of a different kind I guess... Out of interest how much did replacing that lot cost you? >> Stay informed about: 1992 730 - Smell of petrol |
