om 460 la cid 781 Reviews??

I had a 2006, good reliable truck. Always started. o.k. On fuel, wimpy exhaust brake, not a power house, but gets the job done. I did 2 years super-b with it (140,000 lbs).
If it has a lot of miles on it the unit pumps (just before the injectors) may need servicing.
If it's working good then seems to start to use more oil than normal, then it is time to get the valves adjusted, then the oil use goes back to normal.

 

Good engine, but american mechanics are not so well skilled for european engine control, so some silly problems may appeare.

But U can ask me any quation about Mercedes PLD engine control. I like MB, really.

The best advice - avoid full throutle at below 1100 rpm. Rev it up, let engine stay at 1500 crusing rpm for better fuel milage and longer engine life.

The engine is of classical pushrod design with PLD units and "classical" injectors. It has separated cylinder heads for every cylinder. Weak thing is the decompressor valve (it actuates to let truck roll w.o, braking in gear. If engine equipped with this valve - be prepared, it may stuck in open position and u have to remove head to clean carbon deposits.

 

I just put one of these Mercedes 460 motors in a truck everything seems OK but it will run on its own only if I give it a shot either but it won't stay running any idea
