N20 Fuel rail leak
Hi there, I recently replaced all 4 fuel injectors on my n20, but it seems I didn't tighten down one of the fuel rail connections to the injector enough and got a big leak (I think it was to cyl 2). Unfortunately just as I finished this replacement I had to go pickup a delivery, being rushed I didn't properly check to see if all was well and went ahead - it was quick, about a 3 - 4 minute drive but I kept seeing smoke not realizing it's coming from my bonnet.
I finally parked the car at my home, opened up the bonnet and there was a ton of fuel hovering above the injectors and it pretty much reached all the cylinders just sitting on top and of course it was boiling hot. It managed to ruin the ignition coils burning off the rubber seals, I had to use adhesive to get it out as it was still stuck to the sparkplugs, although I'm quite confident I did this in a non harmful way. I did manage to tighten the fuel rail enough so there's no leaks. Does anyone have any idea what damage something like this could cause? What do I need to lookout for? Would the plugs be damaged? Injectors? Oil? Needless to say I replaced with old coils so those need changing. The car is throwing a few misfire and cylinder shutdown codes, I'll attach those. Thanks I appreciate any advice. |

Late Response
Hope all is well in South Africa. This may be an extremely late response. This would not cause any damage. What kind of fuel leaked? was it quality/ premium fuel? In the case that fuel sprayed and splashed on the cylinders, coils, injectors, fuel will evaporate fast. Fuel is actually a cleansing agent. Are you saying its still showing misfire and those cylinder codes that you attached?

All is well thanks for asking, and I hope you're doing good as well. This was a while ago, but this ended up being a non-issue as you said. The knock sensor code was the only real issue, I think the rest were caused due to fuel leaking but that was fixed promptly, and they haven't come back since. I did change the oil pretty soon after that and actually already replaced it again, but yeah the car is working 100% now.
