Blue smoke, engine died, restart witho probs

[sir-winston]

Hi, I´m a newbie from germany. Bought a `97 Ambulance based on a E 350, 140 kmi. Like to convert it to racetransporter for my motorbike.
My problem: starting-fine (little blue smoke, thats it), after 40-80 mi I´m loosing extreme power with lots of blue smoke. Motor is nearly dying ca 2-300rpm. Ignition off- restart after 10-20 sec. and motor runs without problems. Up to the next 10-60 mi, same procedure. Renewed : All filters and liquids (oil, air, dieselfilter) new cps, drained water, checked sending pump and checked tank to sand and other stuff- clean! Normal engine sound, no rough or unsteady idle, no black smoke, good accel. up to theses moments- Don´t know what else to do!!

not sure but sounds like it might be a turbo problem

you said you checked the sending unit , did you pull the filters out of the sending unit and inspect them just curious

Hi Scuffy828, the garage checked the unit and said it´s o.k. Might you tell where it is? In the tank? I think the ambulance might be a little different. Just read the faults: P0603 (Internal Control Module KAM Error) and P 1396 (Glow plug monitor fault Bank.No.2)

that vehicle has two small filters inside the casing of the pick up in the tank, if they didnt look at those filters , that may be your problem, the concern you are refering to sounds like a fuel pressure drop to me , ambulances are known to clog up the filters in the tank therefore causing low fuel pressure and low fuel pressure will cause bad smoke,then when you slow down cycle the key it picks pressure bacjk up again and iot will run ok for a bit and then goes back to running rough , ive seen many parts get thrown at these ambulance engine because of this problem, i would at least start there , even if they looked at the pick up if they didnt open up the casing and look at those filters ,they didnt dig deep enough , i usually throw the filtyers away and let bthe filter at the engine catch the debris

Now I took the fuel bowl out, cleaned the filters and bowl (only a little rust and dirt)-- same problem!!!! I found out, the problem comes when I´m steady at 50-60 for a longer time and then accelerate, or when entering the interstate with a long curve before.

did you pull the fuel tank out

Yes you are right, I took the tank out- sorry it´s not my language (and what´s the fuel bowl)
