So I was under the hood fixing a leaking oil pressure sender and I was feeling up the injector lines, out of curiosity. Anyway #1 has kind of a tapping to it, while the others run smooth. Any ideas?

 

do what now?

 

I am not sure what this could be truthfully, but I think that you just made the best on members quote thread. I will look at mine today and see if I have similar symptoms.

 

I'd appreciate that.

 

mine does the same thing. It also has a brief ticking sound then fades out maybe 30 seconds after being started. I've wondered about both of the issues?

 

Same thing here.

 

It can be a sign of injector failure. Or it can just be the pressure, I would diagnose it with a Solus Pro, Turn that injector off and go from there!

 

I had a cylinder kill test done, oh about a month ago. Said all the injectors were working. I suppose much could happen between then and now.

 

Are you currently having any symptoms of injector or pump failure? Most Likely it's just fine. A Little bit of Air or airated fuel can cause a Water hammer effect.

I understand your concern ....This bosch common rail stuff is getting silly...and silly expensive!

 

EPA is getting silly to, but that's a whole 'nother can of worms there. You mentioned something about a Solus Pro?
