Bought my first truck *1989 Peterbilt 379*

Back at ya, man.. you have a helluva sweet project on your hands...tackling it like a soldier. Happy 4th, for sure.... I'm following~!

 

If you really want to hunt it down, get yourself a can of brake cleaner and a rag, and clean the everliving piss out of that spot, as well as everything directly above it. Put a couple miles on the truck real quick, then pop the hood and follow the fresh oil trail. Rinse and repeat until you find the leak.

 

LoL.. that's pretty "old schoolish"... I do that with the mowers and bikes; didn't think of it "LARGE" Scale..

 

I've done it on everything from a two stroke to a Packard twin 6. Haven't personally worked on one of these big diesel ######## (yet), but I don't see any reason it wouldn't work.

 

Good observation, man. You REALLY made a point. I've not either tried it on a large car... but what the hey?!

 

Hate to do this cause i might burst your bubble. Are you sure you have a peec engine? The easiest way to tell if its a true b model or a peec is the fuel control. A peec uses an electronic control, wires going from the fuel pedal to the fuel pump. A b model is a steel rod from pedal to pump.

The rest of the engine is the same. Only the fuel side is different so even if that parts manual isn't exactly for your engine, it will come in handy.

 

Some B's were peec's

 

Yep. I got one in a 93 w900. But don't know what year they first became available. I know my 91 pete was a true mechanical b. Also i don't remember him ever saying he had a peec. Just wanted to make sure he knew the difference.

 

How's it coming along, btw....o/p??
