Fuel leak from around the intake manifold

As the title states, Im leaking fuel and want to see if it is possible to shut off fuel flow to an individual injector. I have fuel spraying all over my intake manifold and im trying to figure out if it is coming from my injector, fuel rail, or the valve cover. Doing this will help me determan if it is coming from the valve cover or not. It looks like its coming the the VC due to all the engine shaking but then again, its not leaking oil and Im not even sure if fuel can leak out of a valve cover. Thank in advance

Re: Fuel leak from around the intake manifold

Dang Naj, that's a toughy.

Two k can probably tell you for sure what's possible to shut off.

It wouldn't be leaking from the vc unless it's pure fuel getting past a spark plug or at least past a valve, I suppose exhaust valve...
Do you have a service manual?
Should be a breakdown of the intake system in there.

Re: Fuel leak from around the intake manifold

Unless there's something SERIOUSLY wrong w/ your head, it's almost impossible for fuel to be leaking from the VC

Prolly just an injector o-ring, either between the fuel rail and injector, or injector and IM. Extremely easy to find with you watching the fuel rail and someone else click the key to III/prime the fuel system.
