Technical Petrol smell in cabin

[GeX]

Just picked up my new Sei Sporting on Saturday. Its a bit of a beasty, well compared to what i have been driving.
Anywhoo, on the open road its fine but when it comes to slow, stop and start round town driving if i have the vents open (the fans don't have to be on) the cabin fills with a very strong smell of petrol. If i close the vents, ie recirculate the air then it is alright.
Bascily it means i have to close the vents every time i come to a stop at traffic lights etc.

The car has had a 1242 conversion done and custom fitted K&N.
Someone has suggested that it may be the oil breather that is belching out the fumes. It has a K&N style breather on there. I am assuming that if this causing the problem i can just put the breather at the end of a pipe and put it somewhere else in the engine bay.

Hope this explaination makes sense, will try and get some pictures of the car up and posted this weekend.

Mine stinks of what I thought was petrol until i realised it was the bodyline sound deadening I used! Not helpful for you at all but I thought you might like to know!

It'll be the oil breather, the engine blowsback the oil gases thru the filter and gives a petrol kind of smell. I would see if you can make a custom breather pipe that would fit the air intake system so that the gases go thru the combustion cycle with the intake air

I'll look into that..cant be much more difficult than the Cinq, Im going to develop an induction system for my Sporting asap.

is it better for the car to recirculate the air from the breather?


Cinq Sporting - and yes, its broom yellow!

 

[MrDerv]

Yes

I wanna see the bodge that arcs gonna have to make to get his new K&N to fit. Dunno what its designed for but looks huge for a cento engine.

gex, mark has said to just extend the pipe from the oil breather to the bottom of the engine bay.

its better for the engine to not have it going back into the intake, its purley to help with emissions

I use the original Fiat breather pipe, the one which used to go from cam cover to airbox with a smaller vacuum line on underneath. Turned the pipe around so the big neck sits upover, attached the breather filter to that, extended the vac pipe slightly and left that on the throttle body - takes away the oily smell at idle which was overpowering.

As promised, a pic of the breather pipe attatched to an 899cc dome for the GSR kit. Drill a hole and tapp it, then screw in a pipe connector and attatch the hose to it

Cheers for that Brickfoot. Just come off the phone to Peter @ GSR and I should receive my kit tomorrow.

Which would work better that or fitting a completely separate air filter to the breather pipe?

If you don't want the petrol/oily smell, do the above!

a breather filter is cheap and easy but leaves a nasty smell in the cabin when sitting in traffic

Ta very much for the replies, i will see what i can sort out this weekend.
The car is at home and i am at uni so theres a bit of issue there.
I have a custom built induction kit on mine, its basicly a K&N on the end of a pipe, so i will have faff around with it for a while.

This is the best pic i have of it so far.

Ta again.

route the breather pipe to the floor and stick the filter on it


sorted, thats what im doing

[GeX]

Aye thats the easy option, so therefore i will prolly take it.
But t'were mentioned above that its better to route the breather back into the engine and have the fumes go back through the combustion cycle.
