Studded, coolant bypass filter, Alliance water pump. Was wondering if water pump impeller can contribute a quick psi change on a mechanical gauge? I have a transducer and mechanical gauge in Dgas lines. Mechanical gauge raises a quick 1 psi at acceleration then levels back. Was seeing 12psi using top degas line cold. Then used lower line cold and got 9psi same drive. Vented after 30 min and never got above 2.4psi same drive. Local Powerstroke only shop said at 12psi I have cracked heads? Was I getting 12 because too much coolant using upper line? Any info is appreciated. Here's the kicker..last oil analysis showed BORON @ 815.. POTASSIUM @ 722. No coolant los by visual.
To be thorough you need to now the following:
1. what is your coolant concentration?
2. what is the cold level in the degas bottle?
3. are you sure you don't have any slight leaks (ie will the system hold 15 psig of pressure if you pressure it up cold)?
What you posted doesn't sound bad to me. I agree w/ what tfunk88 posted in the other thread.

I will put 15 psi in. How long should it hold?
Exact coolant concentration unknown but I do mix 50/50 Cat ELC w distilled.
Any insight on Boron and Potassium in oil?
Here is a picture of level. This is after I took it down from cold upper level. I'm not exactly sure where it should be cold. Bottom of vertical line cold?
15 psi should hold for at least 4-5 hours, but leak free it should easily hold overnight.
Concentration just needs to be close to 50/50. A few percent either way isn't going to be an issue.
That looks like a decent cold fill level.
Basically if you fill the degas bottle too full, the pressure will go up. If the concentration is significantly weak, the pressure will go up. If you have a slight leak, the pressure may be falsely low. Sounds like you are ok. Personally I wouldn't be worrying assuming your system is relatively leak free.

Okay thank you. I will post psi leak down after my findings. Another areas Boron and Potassium could be introduced into oil? Analysis states possible slight coolant leak.
I’ve run all the tests you have minus the pressure test and have similar results. Your slight uptick on acceleration could be extra volume of the pump, or it could be an increased exhaust temperature function, a combination of both, or even other factors we aren’t considering. I used to run 12 psi before I was deleted and switched to elc - now it more like 9-10 at 190 F. I don’t think you have an issue.
Have you ever used Archoil or another Stiction preventing additive?
Always Rev-X in oil. Should probably use Archoil. I use Scheffer diesel treat 2000 in fuel. Is there a good stiction add. For fuel? Thinking diesel treat 2000 is too sticky. It dries very sticky if I drip on something.

That's good news. Just wondering where the slight Boron and Potassium in oil may be coming from if it turns out to not be a cracked head or head gaskets.

This is the reason for the Potassium and Boron. It is in the Rev-X. No worries.
2.5 hours down from 15psi to 12.5psi cold engine. Using a Schrader valve inline to introduce 15psi. Cap still on Dgas bottle. I'm sure it could be cap too. Not that old though.
You might want to verify that the degas bottle opening is smooth and level where the degas cap screws on. Also, make sure the two vapor hose connections are tight (at the degas bottle and at the other end also).
The leakage you have probably isn't enough to worry about, but if it were mine, I would like it to hold a little better.

Really? This is excellent news. Told the oil analysis lab I use it but of course they know nothing about it for their additive package. Ill look into it further.
