Why Can I Smell Fuel?

[ossie_21]

OK, on start up I get a rough idle (1500rpm down to 1000 & back up again) that settles eventually, the car is blowing a bit of black smoke (no cat but never this much) & since yesterday there has been a strange clicking from an unidentified engine bay location.

Since Wednesday I have been able to smell fuel inside the car, so I'm wondering if there is a leak somewhere, where does it end up?? My car is still getting the same economy, but it's just missing at certain points in each gear still. This link explains the problems I'm getting sorted, but they aren't as severe any more for some reason. http://www.skylinesaustralia.com/forums/in...howtopic=148137

A few of said problems are probably battery related, so next week I will get a new one & all should be fine. The alarm is working again as normal now which is weird

It sounds like a leaky injector, but whats the risk apart from starting a fire if I kept driving it? I'm only asking because the workshop I use is closed until the 8th of January, when the car will be going in to get all of this shit sorted out. To sort the backfiring tomorrow I am going to check the coilpacks for fractures & tape them up, but now this smell of fuel has me worried because the injectors are stock. Big power & boost & stock injectors = not good. FYI I'm not going crazy on it until I get some bigger injectors because if it was an injector that caused my rb25 to go in the first place at 350rwhp I don't want it happening to a 7k engine...

A leaky injector can certainly destroy a motor, if one cylinder is running so rich you can smell it, it will be getting fuel wash and that cylinder will not run in, the other concern is hydraulic lock after the car has been sitting, a leaky injector can fill a cylinder up to the point whereby when you go to crank it, it will bend a conrod.

You can also be blowing black smoke, and still getting a lean AFR if one of the cylinders is not firing correctly.

As you have excessive amounts of oxygen exiting the exhaust, hence, it seems "lean"

I personally, would not drive the car.

If you can smell I wouldn't be driving the car much ,as it probably means leaking fuel in the engine bay since fuel lines and injectors are all in front of drivers position is why u get to smell it first .I had the same problem with mine once it turned out to be a leaking O ring on one of the injectors and I know this has caused engine bay fires on at least 2 cars on this forum as I bought parts from them so personaly I wouldn't be driving it till it went to the mechanic's

Thanks for the replies, sort of what I was expecting I'm going to try & get it to the tuning workshop which could be open, in which case bigger injectors will just go in now instead of screwing around. Either way it's going to leave me without a car so I hope it can get done quickly if they can take it.

It may be worth while just checking the plugs in my opinion, as they may be fouled explaining alot of the above instances, fuel missing and the sort, thats my opinion, leaking injectors wouldnt that mean also there would be an extent fuel smell in the engine bay?. it sounds to me could be a spark issue? Meh keep us updated as well as good luck finding a work shop open until later in the week, they'll all still be pissed from the weekend
