Smoking out breather

petertay · Sep 15, 2019

Just got a 4000 HD Industrial. 172 engine. Crankcase breather blows smoke. Have not checked compression yet (no gauge). Will it for sure be rings and cylinder replacement, or might it be something in the head such as valve adjustment?

Best case scenario - rings stuck. Can be freed with good oil and run time.

I would put clean detergent oil in it and give it some work, might come out of it.

My H smoked quite a bit when I got it, but it has come out of it.

My Ford 3000 diesel smoked terribly from the breather. If ya follow my thread starting about the middle of Page 2 you will see a you tube I did showing the smoker.

I tore it down hoping to find a blown head gasket but not the case. I pulled pistons and found broken rings on two of the cylinders. I am waiting for parts now to put it back together.

Good Luck on yours and keep us postedhttps://forums.yesterdaystractors.c...&postdays=0&postorder=asc&start=0

Replies to my question mention good oil, and detergent oil. When someone buys 6 quarts of oil for an oil change, don?t all stores sell good oil. I?m not
disputing the replies ( thank you for them), but wonder what is being referred to. No one buys bad oil, and isn?t all 10W30 or 40 oil sold today detergent
oil?
I hope the problem might be solved so easily, but what do I do other than change the oil. Might an oil additive help? The oil gauge at startup shows 40
pounds. I haven?t run it long enough yet to see if that is so when the engine gets hot. It is still housed where the auction was. ?Peter

Anecdote: With the engine on my Woodmizer I would use synthetic oil as it started easier in winter. Every so often I would buy synthetic oil from Walmart and it would get dirty really quickly. Changing to a different brand oil, it would stay clean for a long time, then as I kept using it and changing oil it would start making the oil dirty fairly quickly. Do another oil change using Walmart's brand would start the cycle over again making me think that there was more or different detergent in their oil that would really clean out the engine.

Second anecdote: I had plenty of blowby with my Ford 3600 and to limit it I just replaced the rings. Yes there was wear in the cylinder (about .005") but by just replacing the rings the blowby was really reduced along with the oil it burned. Were I younger and planning to use the tractor a lot I would have done the cylinders too but at my age....

All engines blow oil smoke out the breather. That is why since 1968 most vehicles have exhaust gas recirculation systems. It depends on how bad yours is.

When cold, you can actually see moisture coming out as well as blowby.... and cheaper oils will vaporize and blow out as well. SO... a good hd detergent oil might help this over time pending on how the tractor was serviced by the previous owner.

my question is how much oil does it use and are you getting smoke from the exhaust pipe. if not I would not be tp concerned about it. those engines do run a little hotter as some smoke from the breather cap will happen.
