We got this 63/64 4000 industrial tractor backhoe a while back... 4 cyl diesel. When we got it, it did not smoke at all. It is starting to a bit and I want to nip any problems in the bud before it gets worse if I can.
I didn't notice it in the daytime other than a puff on acceleration, which as I understand is normal. However I put a new muffler & pipe on it a few weeks ago, and tonight while moving some hay rolls , in the light of my headlamp I see it puffing blue smoke. At the joint of the muffler there is a little oil running down the outside of the pipe and the flapper at the top is oily. Ill have toi see tomorrow in the daylight if its visibly smoky and how bad.
Now, for the last few weeks, we only use it to move hay every couple days, we start it up, let it get warm for a few min, then move the roll in place, and turn it off....maybe 10 min this takes. My nephew tells me these short runs is not good for a diesel engine... I have no idea if he is right. It doesnt normally run long enough to get the temp up to normal op temps. it never occured to me this was bad... is it? Will doing this make it start smoking? If so why and can we undo the problem now or are we screwed?
It has no problem at all starting.... it starts really easy and fast every time. We run it about 1200 rpm while moving the hay rolls. it doesn't make any odd noise, or stall or surge or anything.... it runs really smooth and quiet.... for a diesel.
The oil seems normal, I don't think its got fuel in it. It did when we got it, but we had the injector pump rebuilt and changed the oil, and it never smoked at all after that until now.
Is this a problem coming from the way we use it every other day, not warming it up or working the engine hard enough?
I'm diesel stupid.... help.
Thanks!
