ROLLED - KX033 PRE STARTUP/POST CONDITIONS TROUBLESHOOTING

[KX033 - NORCAL]

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.

It hydro locked in that 8 seconds and most likely bent a con rod. Time to take the engine apart but first take a compression test. I believe you'll find at least one bad cylinder. Have fun and replenish your wallet, you'll need it.

I’m going to agree, probably a bent rod. I agree, a compression test should tell the tale. It’s been several years ago someone had a similar incident with a tractor and I think the only damage was a bent rod and I think he fixed it himself.

500/500/365 compression results

Weird thing is the first cylinder showed signs of heavy oil/ wet cylinder

 

[5030]

Wet bores will always show high compression. One of them is euchred.

Could be a bad head gasket or something else also.

 

[5030]

Some engines are noted for blowing head gaskets even under normal operating conditions and some aren't. You condition isn't normal so it could be the head gasket or other issues, none of which you will know positively without at least removing the head.

Let me guess, you removed the glow plugs and cranked the engine using the starter.

After removing the glow plugs, the engine must be cranked over by hand slowly several times to clear the oil from the cylinders. When you try to clear them using the starter, the oil can not be expelled through the small glow plug hole fast enough to keep one or more connecting rods from bending.

If you don't have Kubota insurance or other good insurance, you may as well remove the cylinder head and measure the piston height at TDC of each cylinder.

the starter has enough power to bend a rod? that kind of blows my mind.

A way that can happen is it fires on a clear cylinder than hammers the one with fuel or oil jamming the cylinder up.
