A little background, just purchased this backhoe from Iron Planet auction it is showing 2400 hours on meter and meter is turning. It has a fuel drip at the injection pump. It is a Bosch VE style pump. It looks like a common problem with these units leaking at the hydraulic head o-ring. I ordered parts to fix it but watching videos people live with it for a while so I thought it was safe to use the machine a little.
I was moving some dirt for about 30 minutes everything fine when the engine revved up and exhaust was putting out black smoke. It sounds like it is knocking but not sure if it is mechanical or from combustion. Turned the key off and it kept running tried to stall it with load from the hydraulics. It stopped after maybe 10 seconds.
I went a got something to block the intake and I pulled the fuse for the fuel shut off. It tried to start it and it cranked a little slower it did start there was some knocking and it shut off after a couple of seconds with a bit of smoke.
It does have oil in it.
Is it possible it is oil seals on turbo?
Stuck open injector?
Massive internal mechanical failure?
What should be my first step for diagnosis? I was going to pull the turbo first and then maybe valve covers.
I am pretty handy but do not have much diesel experience other than resealing a Stanadyne injecting pump on my JLG forklift. Thanks for any help. I have been lurking on this site for quite a while now.
