While trying to find the source of an oil leak, I was cleaning oil off the hoses from the turbo and found this loose wire tucked underneath. I don't see any obvious place to connect it. Where should it go?




Arrow points to disconnected connector




Wire colors seem to be white with red stripe and black with pink or purple stripe

 

Looks like the EBPV. Look for an the opposite end under the turbo inlet.

 

Change that orange intake tube, they tend to dust engines, look at Riffraffdiesel.com great quality stuff at a great price.

 

you can leave the EBPV disconnected, it wont matter much except warming up engine might take a minute or 2 longer


if the EBP sensor tube is plugged, ( to left of HPOP) then the valve will be energized all the time and you will lose power

 

Welcome to the site, Brian-C.

I agree with what was stated already. If you live in a warmer climate with mild winters, you probably won't ever need the EBPV connected. The EBPV is one of those things we could probably live without, but it's there for some reason, (emission requirement?), anyway. It may through a code, but leaving it disconnected won't hurt anything.

 

No, that is NOT true... throttle position, oil temp, and EBP determine when the EBPV activates . A plugged tube will never drain your battery.

 

You've got me worried. How do the orange intake tubes dust engines? I didn't find intake tubes for this model at Riffraffdiesel.com

is what I bought a few weeks ago

 

Thanks for the link. I didn't look in the right place, apparently. My orange tubes are only a year old, about 3,000 miles, and seem to be in good shape. What is the issue with them?

 

About the connector: I read somewhere that the EBPV is sometimes used as an exhaust brake. When I bought this truck 5 years ago, it came with "O&C Powerbraker" aftermarket exhaust brake installed. I see a cable connected to the EBPV (apparently - it's on the pedestal and would mate with the disconnected cable). That cable comes from the cab where the exhaust brake switch is.
I've never used the exhaust brake because I thought something bad might happen. What are the pros and cons of exhaust brakes? Any cautions about using them?
I use this truck mainly to haul a 9000+ pound fifth wheel trailer, if that has any bearing on the situation.

 

Leave it unplugged, it won't hurt a thing.

 

I'm assuming you are talking about the 2 orange tubes after the turbo, those are fine.

The ones known for dusting engines are the orange tube between the trubo and air filter. the clamp on the turbo end cuts through it and the turbo sucks in dirty air. I've still got them on all my engines, but i also look at them when I change the oil and there still solid.
