Hello everyone
I had some freee time yesterday and despite the heat here in S.E. Texas I decided to drive out to my new place and install a new water pump I purchased and also retorque the head bolts and then reset the valve lash. Everything went well, but I had to run to a couple of parts houses to hussle up enough 8mm bolts to replace the ones that came out of the water pump they where all rusted to much to reuse.
I beleive I have fixed the coolant over flow issue I was having. I have run the unit for 4 hours on 2 seperate occassions brush hogging and have not see the coolant rise enough to over flow the coolant recovery bottle. The temps here have been the high 90's during both runs. About 2 hours into the last run I stoped the tractor and checked the tempature of the radaitor in the 4 corners and the top and bottom tanks. The top end and top top tank reads about 145F while the bottom was closer to 128-130F. This was with the old water pump installed. I only changed the old water pump because I got a good deal on a new pump off ebay and I figured a new pump beats a 26 year old pump any day. I was also supious that the pump might be sucking air past the seal, and be the cause of the bubbles I have seen in the cooling system. I was only able to run the tractor for a about 20 minutes yesterday after I installed the new pump, but as fas a I could see there where no bubbles in enter the over flow bottle. I refilled the coolant system with Fleetguard's Complete 50/50 coolant for diesels (incudels DCA) and added some distilled water to that to get the mix to apprximately 30/70. I will run it this way for a few months and then test the system to see if more DCA is neeed. So far so good with regards to head gasket and coolant over flowing issues.
On thing that I thought I might should point out about using SCA and DCA additives. You must keep an eye on the level you use, too much is a bad thing and it will gel in the system. To little and you do have enough protection. They sell test strips that you should use every time you change your oil that will tell you how much you need to add to the system
Now on to another problem I am having. I think I might have messed up one of the the injectors. Not sure which one, but I am getting some white/grey exhuast when I hammer down on the throttle. Not at start up and not when running at speed or at idle only during the acceleration process and if I put the engine under a heavy load where more fuel is needed. I think I have an injector that is not atomizing the fuel correctly and basically dumping a lot of fuel into a cylinder. I checked and 3 injectors are working well enough that the engine misses if you loosed the fuel line on any of the 3. Any ideas on how I can figure out which is the bad one? I was thinking of order an injector and using it to see if I could figure it out that way.
Your ideas are welcome
