E350 Smoker
Just thought I'd give an update.....
Van had gotten where it was missing worse all the time and smoking most of the time...except every once in a while at idle it would smooth out and stop missing and smoking......checked all the usual suspects(glow plugs and injectors) and was figuring it to be IP related...took it to a new shop specializing in injection and the owner checked it over for me.....seems there was a air sound coming from one of the cylinders....decided to let him pull the heads(glad I did cause it is a MAJOR job in a van)....sure enough, that cyl had valves that you could rock back and forth a lot and crude on top indicating compression was getting past the guides so I'm sure it wasn't seating good....few others showed guide wear as well so both heads are now at the machine shop being rebuilt....can't wait to get my ride back!

Don't sound like the same problems I had...have you checked your fuel filter? My rig never failed to start or run, just got to where it smoked and missed...I believe it would have run till a valve dropped...speaking of...this van only had 127,000 miles on it...what would make the guides wear that much that quick?

The machinist I used indicated this was a problem, albeit I had 337,000 when mine quit. Don't think yours should have been that bad that soon, but I have seen some stranger things happen in a shorter time. When they did my guides, they bored them oversize and install bronze inserts. Kind of a guide within a guide. The bronze is supposed to wear much longer. Might ask your machinist or mechanic if they have heard of it.
