My 4120, which has 111 hours on, developed a problem.
I'm not sure exactly when, but it has been doing it for a while.
It is an intermittant problem where the exhaust gets real smokey, it looks like oil smoke on a gas engine.
When i check the crankcase, the engine oil level is fine, so i suspect it is injection pump related, something causing incomplete combustion.
Anyway, the problem is that it doesn't do it all the time. It usually happens after I've been in the seat 1/2 hour or so. The engine changes tone, it gets like a real low rumble to it, and then tons of smoke out the exhaust.
My dealer says they need to take it in to figure it out. i have two concerns, 1) that i pay them to take it in, and it doesn't do it, and 2) somehow they will telll me it is something i somehow did, and deny warranty.
With 111 hours on the clock, is there any maintenance i should do before they come out?
Thoughts appreciated,
Thanks in advance,
JT
