hi guys! Ive tried relocating the engine vent far from the radiators...like you can see in photos below..I used a reservoir, some oil hose and clamps.. 8/9mm hose the little, near the reservoir











drove about 100miles then begin smoke a lot from the tailpipe...blue smoke..like burned oil...stop the truck and replace my install with the oe cummins and no more problems and no smoke!

so I think I have used too little hoses or fitting??maybe the fumes cannot exit from the vent due to too little hose or fitting? I dont know... I have extended the hose (the one that goes from the reservoir to the floor) on the fenderwell back..and notice a little oil there...why oil not condensed in the reservoir?
can the oil return into the engine?

any suggestion will be much apprecciate!!

Is that for the oil vent from the front of the engine? If so, it looks like the oil would have a hard time "draining" uphill somewhat through a long tube....

 

As you increase the distance from the engine, you have to enlarge the breather tube to allow unrestricted flow of air.

I notice that your line keeps getting smaller, and this is choking off the breather. It doesn't take much restriction to cause a problem, when it comes to crankcase venting.

I have seen many situations similar to this with generators, where you have to exhaust the crank vent to outside air. if the line off the engine is 1", by the time you get to the reservoir, and then outside, about 18 feet away, you are up to a 2" line, to allow for flow.

Try enlarging the lines and fittings, and see what difference it makes.
