Water logged DK35 SE

[KIOTI D]

Slide my Dk35 into a creek and locked up motor , got machine out and removed injectors . Drained out water and changed oil , now when I start machine I am getting white smoke out of number 1 cylinder. Swapped injectors around still number one cylinder . Pulled head no bent valves all looks good. Any ideas?

i would suggest a compression test and leak down test on all cylinders, that may help point you in the right direction. The good cylinders will give a good baseline to compare #1 to

If it isn't a valve problem you may have broken rings on #1

If you hydro locked the engine while running a bent rod is also possible.

If you are lucky it's just a blown head gasket.

Compression and leak done was good, removed head looks like bent rod number one . Piston not coming all the way to the top like the other two. Will now have to figure out how to get the oil pan off. Wish I had. Service manual. Thanks for the input.

See PM for lead on getting service manual. I'm a bit curious about how you knew the smoke (which is un-burned fuel) came from cylinder #1, unless the exhaust manifold was off. A conventional compression test (not leakdown) should have showed low compression on #1.

Thanks for the pm , I questioned my compression test results and had cracked injectors and #1 was dead, I swapped injectors still dead , then I removed exhaust and #1 was putting out white smoke . When I removed cyl head #1 piston was only coming to about 1/8 inch to top deck and the other two were level with top deck.

Sounds like a bent connecting rod for sure. If there is no piston, bore, or crank damage the fix shouldn't be too bad. Good luck.

More disassembly later today , thanks again.

So the one on the left is the good one. Water and internal combustion engine don't mix. Totally my fault . Thanks again for all the input.

Oh boy, let's hope that you haven't completely destroyed the engine by running it after hydrolocking. The bore with the bent rod is probably horribly scored and will require boring out to at least the next over size. That means the other ones must be done too. Ditto the crank journal for that piston. It's not going to be without a bit of pain. Maybe a lot of pain.

All cylinder bores good as well as crank journals , three new connecting rods and one piston , should be good to go.

I've seen several engines that ingested water while running. Can't think of any that had bore damage.

 

[KIOTI D]

Seen of the crime . This used to be a hayfield until we got 6 inches of rain in about four hours.

 

[IndyIan]

Wow that's quite the washout, we didn't get nearly that much rain.
I guess you had a good look at the crank too, with 3 cyl I guess its pretty robust to bend a rod like that.

Yesssss!

if you would like i can send you my bent rod and piston and then you'll have a set. Mine is at the shop on display to explain what water can do to an engine. We had a repo DK55 and it had a miss. We did the injector swap, checked everything for about 3 hours until i seen some green pond algae on the top of the radiator. "Hey that's not supposed to be there, i think its the piston or piston rod." We pulled the head, replaced the rods and pistons and now it runs like a top.
