Bought 720D last year, using it for various things around a small farm. Never had it on a dyno, but seems to have about stock power and sounds good at all times under load, and at idle before it warms up. But after it warms up, both at fast or slow idle it sounds like it"s hitting harder on 1 cylinder. Then when governor kicks in under load, it sounds fine again. Also seems to me and my Dad who was around them growing up that it smokes more than it should when warmed up. I don"t know the rebuild status of the pumps, fuel delivery pump, or injectors. It seems like something gets out of balance with either the pumps or injectors after it warms up. I"ve thought of several possibilities- one pump is leaking past the plunger when warm; one pump not timed properly or drifits when it"s warm, something wrong with the rack, injector warms up and plugs. It doesn"t use oil, but would it explain it if I was losing compression on a cylinder after it warms up?
Hopefully someone else has gone thru this or has suggestions for most likely causes I can track down. Thanks all.
