Excess fuel in one inlet port.

[redlinezak]

Brief lead up to my discover.

Car broke 2 years ago.
Bought new manifold and fitted along with a load of other bits inc fuel system.
Car occasionally got started to be pulled out of garage but thats it and has not been mapped on this new turbo / inlet / fuel system setup (injector values HAVE been changed in power FC).

So Sunday i discover that i have a large inlet leak from manifold to head.
I tested for this by spraying easy start around the manifold (likely to be mainly around number one port).
When i get the manifold off i discover loads of oily residue which i think is fuel but only on number one port.
The other 3 ports are pretty much clean.

Any suggestions as to why?

Piccie of numbers 1 and 2 ports.




Thanks

Hugh Janus has this problem, was a knackered injector iirc?

hmmmm OK that's a little worrying as they have not done any real mileage but just sat there.

cheers

all of mine where filled with fuel, the pintle cap on the end of the injector broke away meaning the O ring popped out of place allowing fuel to flow directly from the rail

[redlinezak]

I'm pretty sure that's not the case as there is no fuel around the rail etc.
I'm hoping its just a mapping issue or residue from the easy start or something.

worth checking the injector o'rings in case they are damaged and letting fuel past

Will have a look and check the o'rings when i bolt it all back together.
