Nearing 5000 hr. Yanmar blown engine ? Lets find out . JD 8800 Rough unit

Looks bad and sounds worse.

This unit was used during grow in .Alsways seemed to collect more water and algae in the sediment bowl than the other unit.

Lately it started puffing smoke so I cleaned out the sediment bowl and replaced air filter which seemed to help for a bit . 

Then I got a text that it died by 13 green.

Possibly the furthest hole from the shop lol.

That is always the way it seems with old gear. 

Next morning at first light I drained out the sediment bowl and removed fuel filter and drained it out .

Had none in stock to replace it so reinstalled it.

Started up after a while and drove it in.

At full throttle it was popping and blowing blue smoke.

Machines nearing 5000 hours,so I'm thinking the obvious blown engine.

Fleets been serviced regularly so I'm crossing my fingers hopeing its a simple fix . 

The above video is after tank removal pick up tube cleaned .

3 cylinder turbo diesel 

A few pics of item removed , was pretty easy and basic.

Original fuel pump was ok.

Had installed a spare to see if that was the issue out in the field.

Pick up tube was plugged up pretty good with silt.

Most likly decaying matter from debris comming of gloves when fill up fuel.

Don't just clean screen.

I had to brake clean from other end and blow out many times to get it all out.

Afew pics of old filter 

After inspection it was pretty gummed up with a slimmy film.

Next morning I picked up new fuel filters and figured engine was blown.

Decided to throw a new fuel filter on and cured the problem . 

Oh happy day!!
