As some of you already know, one of my new Nismo 555s (front left, cylinder no 2) is pissing fuel all over the engine bay when the fuel pump primes. A couple of questions occur...

 

1. I estimate that I have driven about 7 miles with the problem. I took it very easy however, as the fuel smell was overpowering. Could I have done any damage to the engine?

 

2. I am guessing that the problem is a leaky injector O-ring. I assume that it's a plenum off and fuel rail out job to get this sorted. Could it perhaps be a faulty/cracked injector? Any thoughts on this would be much appreciated.

 

Thanks in advance :bow:

Wouldn't have thought it would have done any damage. Was it misfiring or did you just smell the fuel?

 

Plenum and fuel rail off to get to it though :(

Probably is just a dodgy seal I'd have thought.

No misfiring thank fook - it just stank! :rofl: Lifted the bonnet and couldn't believe the little jet of fuel which was hitting the underside of the bonnet. Thank fook it didn't spark up :eek:

 

Has anyone else had experienced the "fuel sprinkler" effect so I can confirm it's a dodgy O-ring?

If it was running OK then it looks like the injector is working fine, pointing to the seals.

Injectors seem pretty tough from the look of them so can't see how they'd leak like that but there's 2 rubber seals if I remember right from fitting mine.

Did you/someone fit new seals when they were fitted?

 

I was in my brothers Opel Manta years ago doing about 120mph when we smelt fuel.

Pulled over and opened the bonnet to see a split fuel hose spraying a huge jet of fuel directly onto the glowing exhaust manifold! :shock:

We turned it off damn quick but luckily it was just vapourising and didn't light :rofl:

yes, it's either a ripped or mis-aligned ring

Did you use new rings or used the old ones ?

 

you are VERY lucky it didn't catch fire.

They were fitted by one of our Zed specialist garages. I would have hoped that they used new O-rings :confused:

 

Many thanks for the replies fellas :bow:
