: >Could it be running too cold?
: Not very likely.
: > Could water in the fuel cause this?
: No. Water only damages parts in the system.
: >What else should I look for? (I have already replaced the injectors.)
: Bad injectors would cause the problem hot and cold. I suspect you may have engine problems. Try breaking the fuel lines one at a time ,ever so slightly when this problem occurs to pin point the problem cylinder. Could it be a piston going bad after getting hot or excess clearance on the wrist pins? Good problem, let us know what you find.
: Good Luck,
: Diesel Dan Could it be a piston going bad after getting hot or excess clearance on the wrist pins? The engine is always cold to the touch. (I can put my hand right on the side of the block.) I wouldn't tend to think that a piston is getting too hot. If it was a clearance problem with the wrist pin, wouldn't it knock on every stroke?
