CT335 won't start

[Omnipotent]

Long story short, we just went into a deep freeze and a snow storm, so the tractor was needed. Went to move the tractor into "position" by the driveway the day before, tractor was hard to start but I just attributed to cold and been several weeks since it was last run, started, drove and turned off. Next morning, again really hard to start, so hard that I needed a battery jumper to get it going...after 2-3 minutes of work, tractor started and off I went to clear driveway. About half way through I notice antifreeze smell, by the time I noticed it I had been using it for ~20 minutes (thought is was steam from snow until I got a whiff) and then another ~5 minutes turned tractor off and parked it.

Now the fun begins, next day went out to use it again (wind blown drifts upwards of 2 feet over night)...tractor wouldn't start. Got out the battery tender again, threw it on 200 Amp and could get it to start for 5 seconds or so, but then it would die. Over and over again. Gave up and got out the snow blower.

Fast forward a couple more days and today was a warmer day (40 degrees) and decided to go take a look at tractor. Same, same. Throw on battery tender and crank away...got it to run for the longest of <20 seconds. Can't place any load on it or dies immediately. Trying to crank up RPM's dies as well.

Checked oil, plenty there. Checked anti freeze, low to empty, added anti freeze (during all the cranking and short stints of running, could not see any leak from radiator or hoses). What I did notice is oil burning through the exhaust pipe (the section where to two pipes join, oil bubbling out and burning). For the record, it seems like when it runs it's running much rougher, although I could be off on that, but seems like a loud knocking that may or may not have been there all along (you know when things are wrong you start hearing everything).

My gut is telling me I blew a head gasket and because of the lack of compression that is why the engine keeps dying after 10-20 seconds...thoughts? Other ideas?

It's a ~2010 CT335 with~1000 hours on it.

Thanks in advance for any help.

Do you think it could have possibly overheated when you got it cranked and working on driveway? The oil showing up on muffler sound more serious than head gasket.

 

[Omnipotent]

Overheating is a definite possibility, like I mentioned I was using it for ~5-10 minutes before I realized it was burning/smelling antifreeze. As well, I can't find anywhere where antifreeze looks to be leaking out, nothing on hoses, radiator or freeze plugs so I'm not sure where it's being burnt/consumed but radiator was definitely low/out when I added about a gallon.

Looking at the engine bay while cranking and running for ~15 seconds at a time, no leaks show anywhere with the exception of the oil in the exhaust pipe.

Pull your fuel bowl and have a look. Make sure you don't drop the o ring.

"A leaking EGR coolant, typically indicating a faulty EGR cooler, often shows up as visible white steam or smoke coming from the exhaust pipe, a gradual decrease in coolant level without visible leaks, and sometimes a check engine light, all caused by coolant mixing with exhaust gases and turning to steam when expelled through the exhaust system"

Lack of coolant
Bubbling oil like substance on exhaust
Poor engine performance
Knocking

Does it have an EGR? The "oil" could be coolant mixed with soot. There are very few ways to have steam come from the exhaust, coolant to disappear, and fluid in the exhaust pipe.

Head gasket or leaking egr

 

[tcartwri]

Your machine does not have an egr nor an egr cooler. There is an overflow tube from the coolant reservoir that will occasionally weep coolant when you are working it hard. That may be what you're smelling. A blown head gasket would be pretty rare as these motors are not under alot of stress.

OK folks, sorry for the disappearance, but back at it. Tractor is now in garage and still runs like crap and will die under any load, including hydraulic (had to get the bucket up to move it). In getting is started to enable the hydraulics to work to lift the bucket I noticed a ton of oil blowing out the exhaust in addition to all the white smoke...definitely not a good sign. I'm leaning towards head gasket due to over heating as the T-Stat hasn't worked in a few years and even Bobcat couldn't figure out why, so I've just left it (RPM, Temp and Gas gauges haven't worked for several years).

Now the question, does Bobcat/Kioti have a manual for the engine? Not being a Diesel Tech nor Tractor guy, this is all a bit foreign to me and before I go ripping it apart I'd like to have an idea of where I'm going.

Thanks in advance for any assistance.

Thanks, I have that one, but it doesn't go into engine disassembly like a Chilton's would have. I believe "3C 3A 4A 3B 4B Series Industrial Diesel Engines Workshop Manual Fits Daedong" is what I'm looking for, but trying to confirm that it is in fact what I think it is. As well, I believe my 2010 CT335 used the Daedong 3B183 Diesel Engine, but again wanting to confirm before I just start ordering things.

Thanks again in advance for any help.
