KX033 - rolled - Pre Startup/Post running condition

[lmcharpentier]

I rolled my kx033 on its side on a steep slope. shut it off within 8 seconds of on its side. It remained on its side for 30 minutes prior me pulling it back over with dozer winch. It sat over night. I filled up hydraulic reservoir to normal, topped of engine oil as a bunch came out the intake side. Air filter was saturated with oil, I replaced with new one and wiped all oil from air box. Pulled the glow plugs and cranked it over to blow any large amounts of oil out of cylinder. Re installed glow plugs and turned it over then off real quick. engine was making weird noise for a second then ran normal but smoked a ton. Machine ran for 20 minutes and smoked less and less. Eventually stopped smoking but under full power was making a weird noise. Day 2. sat over night - started up on idle and smoked a ton. Idled for 10 minutes, eventually stopped smoking at idle and when running it mid rpms and operating no smoke. high rpms the engine sounds like it misses and smokes a little. My questions to you pros are Are there any other locations within engine intake there could be oil and causing these conditions? Engine oil only has some 10 hours of use since 500 hour service. Injectors? I fear something has happened with a cylinder and or ring. Next step for me would be compression test. Any advice much appreciated. Located Northern California.

Do a compression test.

It is always best to allow it to settle for 24-48 hours while you gather all the necessary information for the correct restart condition. So many machines are damaged by not knowing all the correct procedures to keep from making an expensive mistake.

The compression test should point you in the right direction. You did the right thing removing the glow plugs and turning the engine over to expel any oil that was in the cylinders. But as dustyrusty implied, there still could’ve been oil available to drain down later, as indicated by the amount you reported ended up in the air filter.

You didn’t mention connecting rods in your post, but chances are that’s the biggest concern, since oil is not compressible, and if you have more oil in the cylinder than the space between the piston top and the head can hold, then you likely end up with a bent connecting rod(s). Hopefully your issue is something else. The compression test should point you in the right direction.

Compression 500/500/365

first cylinder 500 showed wet glow plug
A lot of oil

2nd 500- clean dry

3rd 365- clean dry

not sure now
Other than use it and live with smoke or completely rebuild it

Do a compression test.

500/500/365

Pulled the glow plugs and cranked it over to blow any large amounts of oil out of cylinder.

You have at least one bent connection rod if you did not crank the engine by hand and used the starter.
The proper procedure is to remove the glow plugs and bar the engine over by hand until the oil is pushed out. Reinstall the glow plugs and let it run at idle for several minutes to clean the exhaust.

Why is cranking it with the starter motor going to cause a bent connecting rod if the glow plugs are removed? The only thing that I can think of is if the cylinder has more oil in it than can be expelled through the glow plug hole and compresses that oil that didn't exit the hole.

cylinder has more oil in it than can be expelled through the glow plug hole and compresses that oil that didn't exit the hole.

That is precisely what happens as the glow plug hole is only approximately 6 mm.

I've seen to many TORO snowthrower's destroyed by 'pressing the electric start button' after sitting 3/4 of a year. IF owner would MANUALLY pull the recoil cord, they'd FEEL 'something' is sticking or stuck. What happens though, push the button and snap all the rings, destroying what could have been a good machine.

I like the routine of using compressed air to blow fuel out of a cylinder, using a rag around the 'exit' hole of course !
