Something I have seldom if ever seen discussed here is the little return-lines and collars that connect along the line of injectors.

I never read of anyone giving them a second thought, nor any TECH articles about servicing/repairing them.

Although I can't truly tell for certain, I kind of think a couple of the little collars on one of our trucks are leaking/dripping fuel.

When the engine is idling, I can see a wet shiny ring of fuel sort of vibrating around the bottom perimeter of the collar.

And, those little "pockets" beside the valve-covers and adjacent to the injectors are usually standing full of what I think is fuel.

When parked, almost directly underneath that area will be a wet spot on the ground.

I am not meaning a big fire-hose gusher; just the slightest bit of an occasional drip.

I have no idea if it gets more or less when driving and at speed.

 

There are little horse shoe shaped washers in there that seal the line to the injectors. I got some genos garage for my truck before.

 

Tighten up the banjo bolts a little until every thing dries. Something I always recall from my diesel tech classes is my instructor telling us that fittings don't have to be white-knuckled. Just snug them up and if they leak, tighten them until it stops.

Or until the bolt breaks which ever comes first LOL just kidding

 

Are you meaning those smallish bolt-heads that are down on the side of each "collar" thingie, maybe 8MM heads ??

Thanks.

 

They WILL snap.......Ask me how I know.......

 

Yep! 10mm actually. Not sure of the torque spec but I'll bet it's low. I just get them snug with a 10mm wrench.

 

Thank you kind sir; that sounds like something that isn't above my abilities.

I will get that addressed at the soonest.
