White Smoke (billowing)

[Wagtail]

Re: the coloured caps falling off (in between waiting for the white-smoke issue to be resolved)...

Put a corresponding number of tie-wraps (zip-ties) on the male & female lines: 0-0, 1-1, 2-2, 3-3 and you won't have to go through the guessing game again.

My FEL 3rd function ports are both female and I've also done this, 0-0 and 1-1 for when I attach the 4in1 bucket. Same thing if you run a grapple.

I'm not sure if it was the proper way to do it, but after spending 400 bucks on a new pump I had alternating ends on my pump, splitter, and backhoe to prevent reversing them again.

Take the dipstick and check for a fuel smell. Sounds like an injector issue causing excessive fuel =white smoke = crank case oil overfull of a diesel oil mix. Do not run the machine.

I think I'd look to the hydraulic pump. I personally don't think you've done any major damage other than blow the seals on the hydraulic pump. If you change the oil and add hydraulic fluid your just going to fill the crankcase again. Fix the pump and see what happens.

Screwing up the order of the disconnects won't hurt anything. It's no different than hitting the ends of the cylinders or overloading, the oil just bypasses.

The steering and implement pumps are run off the timing gear train on the front of the engine. Sounds like a seal popped out of one of them, there should be a pump on front and one on back of the housing. It must have been close to failing and it was a coincidence.

The crankcase probably got too full of oil and started pumping it out the breather tube into the intake. I sure wouldn't have fired it up a second time, neutral is there for a reason, just drag it and the bucket out of the way. After you shut the engine down the first time the oil probably had time to fill the intake manifold with oil, then a cylinder so when you started it back up it probably partially hydrolocked a cylinder.
I would pull off the pumps, noting which one lost the seal, cover the ports with duct tape, change the engine oil, fire it up and hope you don't have a bent rod or broken piston. You might have got lucky and just need a pump. If a rod is bent you'll notice a weak cylinder and eventually a loss of oil pressure, and possibly some banging in the basement.

UPDATE:

so it turns out that a seal blew on the hydraulic pump and dumped a ton of hydraulic fluid into the crankcase. It's currently at the shop while they wait for the new pump to come in. I know someone had said that mixing up the hoses shouldn't have done any damage but I can't help but think that the timing (5 minutes before) is more than just a coincidence, especially considering that I put that loader through it's paces **** near every time I use it and it's never so much as hiccuped. I appreciate the input from everyone. Hopefully after they get the pump replaced and flush out the contaminated oil they won't find that I had caused any more damage to the pistons by running tainted oil for a little while. Best I could tell, it was still "running" when I shut it down.

This gets me thinking, I will do the zip tie idea.
I didn’t know such a mixup could do that.

It can't, just a coincidence as long as the pressure relief valve is working. An unfortunate coincidence, but still just a coincidence.

I'd be more worried about hydrolocking the engine from the 2nd start up.
Hydro oil isn't enough different from engine oil that you would have caused any problems due to that. I'd guess you can rack up several hours running UTF in a crankcase without any issues. It's close to 30w.

You got lucky that the engine didn't run away.

Thanks for the info and the update humanparody. Nice of you to take the time to do so. Helps out others later on reading the posts

I learn so much by following these reported problems!!
