This is Bezzer with my problem. It has the 6.5TD with the F Engine (does not have the EGR valve). The engine has 79,000 miles on it. This problem started about 2 yrs. ago. At every cold start (like the next day). The proper way to start this engine is to turn the key on and watch for the glow plug light to go off and then start the engine.
As the engine starts turning over - I hear a "poof" out the exhaust pipe. Then after about 8 seconds there is a "poof" from the passenger side motorhome next to your leg. That is the turbo side of the engine. I have watched the cold start up at the engine and the rod on the new wastegate did not move but something made the "poof". I shut the engine off and waited one minute and restarted the engine and no "poof". I have checked the new vacuum pump for vacuum at the hose that goes onto the wastegate and it was 15 lbs. at idle at the cold start.
I have checked the ohms on each glow plug on that side of the engine. All four showed 0.5. Also checked the voltage to each glow plug wire unplugged with key on. All had 6 volts....as manual states.
If we go for a drive about 50 miles and stop for fuel and restart the engine...there is no "poofs" anywhere. No white or black smoke from exhaust pipe. The engine performs perfect when on a road trip.
Anyone know what this "poof" is or what's causing this "poof" after 25 yrs. without a "poof"???

Inspect the exhaust system closely, signs of soot etc. Does it poof if you keep cranking it or does it poof when it does fire up?
