International 464 Diesel Smoking?

Anonymous-0 · Jan 11, 2009

I recently purchased an IH464 and it starts and runs just fine and seems to have plenty of power,but it smokes heavily and it doesn't smell like oil more of a diesel smell.Whenever I start it in the shop it leaves a haze that takes about an hour to go away lol. Is this normal i've heard these motors are pretty smelly,but i've never heard of this haze.

Yeah but it smokes in all temperatures I remember when the previous owner used it this summer and it did the same thing.

A diesel take a bit to warm up as she has to make her owen heat and a diesel need to be above 165 degrees to start burning all the fuel now i am taking water temp. here. Now not seeing the tractor it also maybe pump timing or your injectors may be slobering , this problem is something that you are not equipped to handle . and if you are not use to working on diesels then let a pro check it . Engine compression could be low due to being plum wore out to broken rings from someone putting either to it to start it or could be that someone did a valve job on it and did not do it correctly and set the valves to deep into the head and this will also cause low compression and smoking .

Hi Tyler, my brother has a 454 & 495 that both have D-179 German Diesel engines same as your 464. They both do the same thing when it is cold. Solution is a recirculating block heater or start it and drive it out of shed to warm up.
Another option to help is when it is cold do not pull the STOP/START/RUN lever all the way to the top, leave it down about 1/4 inch from top and this will give less fuel to the engine and allow the fuel that is being injected to burn cleaner.
Did the previous owner make you aware of the START position on the STOP/START/RUN lever?
Another helper is to put a curtian of some material on the front of the grill BUT if you are working the tractor hard you must watch the coolant temp or remove the curtain. Farmers in my area used a couple bungee cords and feed sacks for the winter on the grill in front of the rad.

The german engines are the stinkiest around. Many years ago, our service rep told us a dairy farmer had taken IH to task as he claimed it was making his cows sick. IH did a lot of changing on these engines, most important one was to put in different pistons to raise compression ratio and changed the tips on the injection nozzles to what they called a low sac tip or something like that to dercrease the volume of fuel hanging in the tip of the nozzle after injection . These changes helped a lot and also made it so the valve recession in head was not nearly so critical. Using a lighter fuel in cold weather really helps the slobbering situation also, just burns easier. On the starting procedure, well, there was a B and C series inj pump, and they required different procedure for starting. Not that one was better, just different. They are still stinky though.
