1966 DIESEL CASE 530 CK QUESTION about water in fuel

southernbound · Aug 17, 2017

OK..its a 1966 188 DIESEL CASE 530CK ...I believe it sucked in alot of water through a auxilary tank that previous owner put on...I was trying to get some wood moved before i replaced the fuel tank and it just died...(like I pulled the fuel cutoff but with white smoke).. So, I drained tank (water in it) Drained all lines and replaced/blew out...Replaced filters...Bled air outta system ( fuel at every injector).. Still will not start.. Could there still be water down in injectors (what is bleeding out og injectors looks like water/fuel btw..)? If so, whats the next step for me? I also thought maybe return line clogged so I replaced rubber line with new and blew out hard line..

Thx again in advance

Are you saying you are getting water/diesel out of the connections to the injectors when you try and bleed them?

If so you have indeed pumped water through your fuel injection pump which is not good news.

Ideally you will need to have the injectors overhauled, You don't want water sitting in them for any length of time. At all.

I don't think water will pass through those injectors but I could be wrong and you could try repeated cranking if you have cleared the system of water up to that point.

ie. Disconnect all the pipes to the injectors and crank the engine until you are sure you have clean diesel coming through from the tank to the pipes. But it seems you are trying that already. Pull the injectors I think. Protect the nozzle tips when you are handling them.

Looks like a mix coming out of lines feeding injectors...Can I pull all lines including return completely off at injectors and crank?

Yes that will purge your FI Pump (hopefully). But you still have the probable issue of water in your injector bodies.

ok..thx..I pulled feed line off individually and return lines off individually as well... I'll try both at the same time now

Sweet victory!! Thanks you very much spanner...I have no idea why bleeding individually didn't work and together did but thanks a million..It started out a lil rough for a few seconds but now its purring like a kitten again..I was nervous as heck seeing that kinda water in the tank. I did add some diesel treatment to it as well (hopefully take care of any residue of water)

So..lessons learned...Never make the mistake of assuming that a auxilary tank a previous owner had put on is water tight..lolo..Always check.
