Ford 7.3L Power Stroke (1999-2003) :: Won't Start - Bad Injectors - Coolant In The Oil?
So we begin w/ another saga for the 7.3l Excursion......
A few months ago it started running like crap, real crap and blowing white smoke like crazy. Well I knew this from a previous episode and I had a bad or multiple bad injectors. I tried to trouble shoot which one it was and maybe just replace the one or two....but no it was worse than that. So Life was really busy it kinda got shoved aside until now.
I pulled all the injectors and had them rebuilt locally ..nice. They ended up being with mech for a couple of weeks because he went out of town...no problem. Well this entire time my rig was untouched and when I got them back #7 was full of water.....great, bad injector cup. #7 was the only one, the rest were dry. So I drained the radiator and the oil and left it overnight to completely drain and installed the new injector cup in #7. Next day I refilled via both heads because the valve covers were off, 4 gallons of oil and a new oil filter. Cleared the cylinders via the glow plugs and commenced to trying to get her started. Nada......just cranks, killed the batteries, recharged over night and left the box on them and still nada....but the oil was still very milky at this point.
So tonight I pulled all the injectors back out and drained the oil again, still a lot of water. This time I sucked out the HPOP reservoir and got a more milky water/oil out and I'm leaving everything open all night.
In the am I plan to check my overflow water level in the hopes it remains at the same level...if so I will reinstall all 8 injectors and refill the motor w/ 4 gallons of fresh oil and try again.
Oh, while I was attempting get her started I put my buddies Snapon scan tool on it and I got the p1271-p1278 codes w/ the buzz test. (low side to high side open circuit between idm and injector) So I found the pin test with everything connected at the idm pigtail and everything tested good. So I'm back to my not so fresh oil anymore is the culprit to it not starting.
Am I missing something here?
Also....another fun filled fact is that I seem to have a fuel leak somewhere at the rear passenger side. Every time my fuel bowl fills up, if I shut the key off it will drain down. Sometimes I can see fuel dripping quite vigorously onto my starter but I can not see where it is coming from. I have while it was dripping ran my hand along the head and the fuel lines and can not find where it is coming from. Any thoughts as to where in the hell this fuel could be leaking from?
Ford 6.7L Power Stroke Diesel :: Coolant Additive Low Warning
Got a warning Coolant additive low and checked the coolant reservoir is above the cold fill line on the big reservoir and on the small reservoir(near the Radiator neck) it also is above the fill line. What could the message be telling me? The second message is "Cleaning exhaust filter" and it come and goes. Is this a warning that I need to do something about?

The other day I got the check coolant additive message. I've heard that you need to test this every so often. My truck has 67,000kms. so maybe 45,000 miles ?? Anyways.. At first I thought it was a LOW coolant message not reading it thoroughly the first time.. So I was quick to check the coolant level. The level in the drivers side looks ok but the passenger side seems a bit low. I can't not see any leaks what so ever. So question 2. Are both overflow reservoirs or is one for this coolant additive.

OK, just about to turn over 17,000 miles on my 6.7 and got the message to "Check Coolant Additive". So I came here and did a search, read a bunch of post, gained a little information, but not enough. You know how it goes with the subject gets off track and never comes back to course many times.
So my question is, do I purchase the kits, from what I read it would appear that there are two different test kits required.
Or do I just take it to the dealership and have the test performed? Also from what I have read it would appear that this is a timed message response and not an actual computer generated test...correct?

Got a "check coolant additive" message in my message center, but the owner's manual isn't too useful explaining what it means or what I should do.

Driving to work this morning and I get a notification "Check Coolant Additive". Sure, I've got 12,100 miles on it but come on. Dealer dip a test strip in the coolant to check it out. He says it only takes a few minutes to check provided the engine isn't too hot. I guess the "coolant additive" is something that the computer monitors to make sure the coolant is still good.

My 2015 F350 6.7 has 13,400 miles and displayed the check coolant additive warning as I pulled into town from an 850-mile round trip this weekend. If the radiator in 2015 is still the same as the one used in 2012 etc discussed in another thread?
I will call my local dealer tomorrow. I do not see any obvious leak at this point. I had the oil changed before taking the trip and assume all fluid levels were checked.
Ford 6.7L Power Stroke Diesel :: 2011 F350 - Coolant Additive Check Message
Got the warning on the message center.. 2011 F350 38,000 miles. I am not original owner, has lifetime POWERTRAIN so thinking of letting dealer handle this,,,but..?
With the importance of these cooling systems.. and coolant being in there for approx. 60 months.. I am thinking why pay for test kit or pay dealer to test it and add additive...
I guess I could just buy the oem coolant and distilled water and drain & fill it myself... but can I use garden hose to flush? Or just better to let FORD handle it?

How does one clear the computer to prevent the display "Check Coolant Additive" from appearing every time I start the truck. I know that a chemical test is needed to determine the status of the coolant.
View 2 RepliesFord 7.3L Power Stroke (1999-2003) :: Low On Power / Injectors HPOP Or Tune?
So I have a 2002 7.3 Excursion and I think it is low on power. ICP is falling on its face when on a 60 or 80 HP tune. I have some boost leaks at the plenums and will work on that but that shouldn't cause my ICP to tank at full throttle. Following are some numbers I pulled with WOT runs up a 6% grade.
16PSI BOOST
EXHAUST PRESSURE 40
ICP 1900
80%IPRDC
this is with the 60 or 80HP tune on my DP-tuner. If I ease into the throttle I get
2700 ICP with
45%IPRDC
but if I stomp on the throttle it stumbles and ICP tanks.
Running the stock tune I can maintain
2700ICP at
40-45%IPRDC
Is this my HPOP being weak, or worn out injectors, to much of a tune or a combo of all three?
Ford 7.3L Power Stroke (1999-2003) :: Injectors Barely Spitting Oil
This is a 1999 with 200k on it. It has a really bad hpop so valley is full of oil. Haven't removed the HPOP to inspect the non serviceable plug or the hpop gasket. doing that this week. This truck I just bought and it has aftermarket injectors so dont know the miles in injectors. once the oil leak is resolved I can then give the injectors the once over to make sure theyre okay. Question is how much of a stream of oil should I expect to see as the engine runs?

So I got all 8 injectors upgraded and excited when I get them back I put them all in in kind of a rush. And in that rush I left the cylinders full of excess oil. So obviously when I tried to start it hydro locked. Angry at myself. I kept trying to crank hoping it would fire and just shoot that oil out. Nope, so I went back to taking all the glow plugs out and firing it all back out. Put it all back together then tried to fire her up. Took a minute but she started and I let it run for a while. Hit the gas a few times and then it died. Couldn't get it started again. It would just crank, I checked the icp and ipr and the icp did not build above 35 psi and the ipr was at 98.04% so I just figured the o rings blew out when it hydro locked.
So I took it all back apart put new o rings on, took my time and put it back together right double checking everything. Got it all back together and went to start it, it would just crank around 160-170 rpms, battery voltage at 10.6 icp built up to 140 but now it won't build past 40. Ipr still goes to 98.04. The engine ran just fine prior to injector change, I put a new upgraded hpop prior to injector change, new ipr, icp, cps. Everything checks out, but it will not build oil pressure while crank I've killed a set of batteries then went all out and spent 350 at napa for some optima red tops. I did notice the cylinder 7 injector is the AE injector. It suppose to be in cylinder 8, idk if that's affect the oil pressure building up?
But as far as I know, I'm not building oil pressure. So idk if the hydro lock could have ruined something to keep it from building oil pressure?
