I've got a 2000 cummins and recently when I bought it there was a leak in my oil return line. I got it fixed and recently when I accelerate it builds boost then seems like it loses it all. It sounds more like air escaping. It's hard to explain. Any help would be appreciated

 

What vehicle and what year? We are not mind readers.

 

Well I put on my post it's a 2000 dodge cummins 2500 ...

 

I obviously can't read. Lol. My bad.

 

lol that's okay
