Oil in the exhaust?

I"m noticing lately that I"m getting oil in my exhaust(I have a "57 Major). It actually collects on the rain cap and drips back down the muffler. The tractor still starts good and seems to make decent power, idles fine too. In the preceding post there is mention of white smoke. I get that too, when I give it a shot of throttle, then it goes away more or less. What do you think? Is a ring job in order? How do I check compression on this engine, with no glow plugs and all?

Although this is a bit late for a last years topic; I had the same problem with a perkins engine, replaced the thermostat with a good stainless steel 180 degree unit, and all the "drippings" went away after an hour of running.Temp wise it runs at 180 summer or winter, so hope it helped.
good luck

Could I suggest valve guides & seals may be allowing oil in through the exhaust valves? Maybe the cool running isnt expanding the metals sufficiently & the oil thining out is also adding to the problem. Just a thought.

I believe You are totally right.These new multi grade oils break down much faster than the straight 30.Cold weather may crank harder,but if you are gonna use it in the winter just keep a working block heater on the engine.

Sandy,

Do you still have the old pump? I need a stop mechanism for my Super. You have my e-mail and phone number.

It may be time for a rebuild but there are some other considerations. Cold running due to thermostat problems, short running times, very cold weather, idling or low load running will cause the fuel and oil in the cylinders to burn incompletely. Ensure you have good fresh crankcase oil and give it some real work to do to get it really hot. Partially cover the radiator if necesssary to keep the engine warm enough. Hope this helps.

Don, I think you're on to something. I haven't really worked the tractor hard in a long time, it's been cold lately, and I'm not sure if there's even a thermostat in there (although there probably is!). In fact I usually run the thing just off idle to do a bit of snow plowing and other fooling around, perhaps I should be working it harder. I've noticed that the rad barely gets warm and the head can still be touched(although it is warm!) when I shut it down. Hmmmmm.

Didn't you have a block heater put in awhile back?Try plugging in before you use it.I always use a block heater on my 6.9 Ford in the winter and it starts easier and burns cleaner than without it.I don't run my Super in the winter much but it does smoke more when I do run it and the flapper seems wetter.Maybe a hotter thermostat is not a bad idea for a winter tractor???

I don't think a hotter thermostat is necessarily the best answer. I think a radiator shield to keep the temperature up to 180F or so would do the job. In cold weather and light load the engine may very well not get hot enough to open the regular thermostat very much. If the head is cool enough to hold on to, I certainly think the engine is too cool. A working temperature gauge would be handy to keep the engine hot without overheating. Overheating could be lots worse!!

Yeah, I put in an inline coolant heater, and that made cold starts a lot easier but the black oil in the exhaust is what concerns me. I think having read posts on this and other boards that lack of use and particularly hard use is my biggest problem. Ohhhhh, I wish I had a backhoe/loader combo on this thing, it would never stop!!!!! !

I wouldnt worry about the oil in the exhaust if it isnt smoking blue when warmed up or using a lot of oil.I have owned a lot of big farm tractors.Work'em hard all spring and summer,and they burn clean,but put a bale prong,blade on'em in the winter and they all will slobber some black runny gunk out the stack.Youve gotta build a fire in'er once in a while.

Thanks for the quick replies. I like what you said about building a fire in "er. I"m also thinking that the 15W40 might be a little to light for something this old (worn?). What if I changed it out for straight 30wt?
