Sorry for leaving you hanging. I went to bed.

It looks like it is just leaking from the sensor, not dripping from somewhere else? As far as the sensor is concerned, I would unplug it and try tightening it before assuming the worst.

What power level are you running?
Diesel soot + a bit of raw fuel (from high-power tunes) + heat + a bit of condensation = that colour, gooey mess seeping pass a loose clamp.

Okay thanks ill tighten it tonight and clean it up and check it in a few days, I could really see any leaks higher up.

I ran hot for 3 days never hit wot, now I'm just running wild, I tightened all the clamps as much as I could cleaned it up and will check again when I check the sensor, I take it it's normal?

I really haven't seen any leaking sensors/bungs on mine, but every truck is different. As for tightening "stuff", if you guys (Sask) have been having the kind of weather we (Alberta) have, might need to re-torque any recent installs.

Torque a bolt in a 15*C garage, drive around (getting it all hot), then park outside in -40*C, the bolt will need to be re-torqued once cool.

Like you said, keep an eye on it and report back.

Your truck doesn't always leak.

But when it does, it leaks pure excellence.

Yeah joker makes sense and that kinda what I figured, this is actually the second time retorqueing then so we will see what happens now.

Jeff get Jackie chan outta here!!! Haha took it off Hott cause I wanna put the pedal to the metal and me have no lift pump. And ya I've checked a few times since install haha doesn't hurt, but Fack hope nothing serious with that sensor, 2 weeks after annual check up and 1 week after performance installs, me probably no more warranty lol
