After removing and replacing my high pressure fuel lines and intake manifold and intake cover plate (new gasket), even on short trips now there is a nasty leak somewhere and it is enough to make a significant puddle under the truck.

I thought maybe it was the fuel line to head connections just needing snugged, which might leak diesel, but the liquid doesn't smell strong enough to be diesel fuel. I think it is oil, but I"m not sure where it is coming from.

I think I ruled out the breather box at the front, because the mess doesn't start until just underneath the cylinder #1 fuel line inlet.

Has anyone else had this experience after replacing fuel lines and intake? What can I do to get this leak stopped?

Thanks in advance

 

I would clean the engine to the best I can with degreaser, then drive a short distance and look for the place it leaks.

 

Thanks Paul. I found the leak. It was 1 or more of the injector connections on the head. The weird thing is, I thought it was oil, not diesel, because of the consistency and smell.

Anyway, the leak is gone now.
