My Backhoe needs and engine rebuild

[hayden]

I just got home from talking to the mechanics at the New Holland Dealer. They think it's fuel and hot hydraulic oil. They don't think it's possible for hydraulic oil to get into the engine. They think it's the injector pump. Might also be the injectors, but most likely the pump.

I need to get the oil analyzed before I do anything. They didn't think I needed an rebuild based on how quickly the engine starts, and that I don't have any power loss. Apparently, I have one of those engines that should last forever.

A couple concerns they had was that the smoke was white. They said that it should have been black if it was diesel. I didn't smell diesel, and I should have if it was diesel. I don't know what I smelled, I thought it was burning oil. It smelled bad.

Now I need to find a place to send the oil sample. They send it to a place in Shreveport but didn't actually do that themselves and the person who does that wasn't there. I'll start by searching for that place and then see if there is one that's closer. I've never had oil tested before.

Fuel would have been my first guess too. Blackstone labs in Ill can do sampling. I have been using them for years. Call and they will send you one or more sample kits that you then fill and return. Cost is around $30 per sample. I have heard Cat dealers can do sampling too, but I've never gone that route.

Let's hope for an injection pump and injector rebuild to get you back in operation.....

Another indicator of too much fuel in the crankcase can also be oil/fuel mixture coming out of the breather tube.

Not sure if yours has a turbo or not, but I ran a dozer that started smoking white really bad. Turns out the turbo was in the process of failing. New turbo and no more smoke. But it was also leaking oil into the breather so the oil level was dropping not rising.

The white smoke cloud happened after I dug up a tree and I was pushing it out of the way. I was revving the engine and using all its power to do this. That's when it started smoking like crazy. Huge white cloud of smoke coming out of the exhaust and the breather tube that's under the engine. It lasted until I parked it.

If it was coolant, wouldn't that make the oil milky? The oil is sooty black. I smelled it yesterday for the first time and it smells like diesel. I never thought to smell it before.

No turbo. Just a simple, basic 304 cubic inch four-cylinder Ford diesel engine. They guys at New Holland said it was the last of the great engines before New Holland ruined them.

The mechanics said to replace the injectors too. Maybe I'll do them first and see if I get lucky?

Definitely do the oil analysis. No use tearing anything apart until you know what area is causing the issue. You need to find the root cause of your problem first, before tearing into it. A basic compression check might help as well.
