Is smoke from the CC vent from start up to finish bad? It ran hot, up to 230 for a few minutes, so I changed the oil. It was due anyway. Then the smoke started.
Crankcase vent
- Thread starter Brake Weight
- Start date
The "amount" of smoke or blowby from the crankcase vent is what would make it bad. Did this blowby just start at the overheat? None before?
How does yours compare to this? [ame=http://www.youtube.com/watch?v=OLwUS_QGOhU&NR=1]Yanmar 155D Crankcase Vent - YouTube[/ame]

About like that. I use Rotella 15w-40.

The blowby in the video is pretty extreme. I get wiffs at idle sometimes after a hard working of the tractor, even when i rev it up to 2000rpm sitting, ITS no where near like that, faint wiffs taht can only be seen in the sun.
If yours is doing this i think that you either have a bad head gasket which is letting compression into the lower end (would think you would see water in there too?) Or you have worn rings. If this just happened i would keep an eye on it, but if it dosent get any worse i would just live with it. It will probly go another thousand hours easy, just keep checking the oil.

The blow-by in the photo is pretty strong. Would you think that changing the oil would stop that kind of pressure..If you had the proper type guage you could read the pressure...We have to read the big cummins in order to assess the repairs as needed... I Bet the little yanmar in the video has a lot of running hours?

Thats pretty extreme. Keep an eye on your fluids if you end up using antifreeze or water you can pretty much bet it blew the Head gasket or warped the Head. Watch your Oil for signs of water in it. etc.

For those that dont follow this board as much as others, the video is not the originals guys tractor. This is a stock video pulled from youtube that Winston always posts for those when "blowby" is brought up. Its a good example of extreme case which is why he posts it.

I just changed the oil in it and ran it about 4 hours the last few days. No loss in the radiator and the oil is still clear. I did run a Fram filter this time. Should I go get a different filter? There's no knocking to indicate it's starving for oil. I was doing some heavy tilling and some medium bush hogging on the new oil. The tilling was last years small garden, plus about another 1000 square feet of new ground-we got some good rain the day before.
I was looking at Hoye's site and it's gonna be costly to rebuild this myself, if need be, let alone pay someone to do it. I'll run it until it's blantingly obvious where the issue is and start ordering parts. Might as well go ahead and split it and get my high gear back while it's down.

Personally, I think the Fram filter is fine. Any engine with excessive blow by will contaminate the oil much faster. That is why we run detergent oil. It is picking up all the hydrocarbons. You might want to change oil and filter a little more often. I would guess your rings are worn. As long as it starts ok and oil usage is not out of hand you could keep on trucking. No doubt overhaul is in your future if you have blow by equivilant to the video.
Forgot to ask about what caused the over heating? Is that still a problem?

The overheating is/has been an issue when ran hard. It's progressively gotten worse. I changed the water pump and did a good flush last summer. I used distilled water, water wetter, and 1/3 antifreeze but it still gets hot. Once it's hot, it takes a long time to cool off. It has trouble transfering the heat. A few squirts from the water hose drops the temp to about a 1/4 of the guage after a few minutes of it evaporating. Ima try to flush the radiator with a mild mix of muratic acid before the summer hits down here. I can see through the fins at the engine, so the outside is clean.
