Yes. Go beat it up, good and hot, release pressure, then have some one take it up and down to about 3k rpms slowly while you squeeze the bulb and SLOWLY let it suck in from the degas bottle. Don't let it ingest coolant

Ran the test a couple times. No sign at all of a leak.




But I still have a small coolant leak that shows up when I let this thing sit for a day without starting it. Usually I don't start it Sunday, and there will be a small coolant puddle under the rear, passenger side of the engine Monday morning.

Heater control valve?

 

[DEEZUZ]

Drips onto valve cover kinda and looks like rear engine leak

I'm going to pull the charge pipe and inspect the egr delete on Saturday.

And this test was done after a high heat run and someone taking rpms up and down gradually?

Yes, I had my dad bringing rpms between 2k and 3k while testing. I'm thinking the reason the Degas bottle was leaking was just a weird circumstance from the super cold weather we had. I'll get this thing up to operating temperature, release the pressure, then beat the ever living shit out of it, and I can't even get the gauge up to 10 psi.

I'll have to take another look to see if I can find where the leak is coming from.

Cleaned the coolant filter....look at all that crap that would have been in the oil cooler if I hadn't done this external system. Oil changes are a bit harder, but at least I'm not replacing the oil cooler once a year.





There was so much caught in the filter....

 

[DEEZUZ]

I just don't get how your block is still so dirty. Is that like gritty stuff?

 

[GTPpower]

It's rust from what I can tell. It sticks to a magnet.

 

[Jon01]

Thats nuts there's that much shit in the cooling system.
Random thought - Have you checked the ph of your coolant?

I haven't, but it's only a year old. Ive owned this for 4 years now, and I think it's got new coolant just about every year.

Pulled out on the highway the other day on running my hottest tune, and hammered it. Fuel pressure dropped way down. Did the regulator seal rip again?

 

[DEEZUZ]

Did you put it in correctly? I don't remember. The cone side goes inside the gold piece.

What's your fuel psi regularly at? Shouldn't be above 65ish

 

[GTPpower]

Yeah, I did. It's been great for a year.

Fuel pressure is usually right at 60 psi. Now it seems to have dropped to 55.

 

[DEEZUZ]

Well that's where I'd start

 

[GTPpower]

I'll order a new one. If my housing is worn, could that cause it to keep failing?

 

[GTPpower]

I ordered a new blue spring kit.

Btw, it looks like you are right about my heater valve leaking.

 

[DEEZUZ]

I've never ever had a repeat failure of a return seal

 

[GTPpower]

Swapping out this heater control valve....am I going to make a big mess if I just remove the degas cap, or should I drain some coolant out?

Got pinch pliars?

Pinch both sides of the valve. You'll lose a splash

I don't. Am I going to lose a lot if I don't?

 

[DEEZUZ]

I don't. Am I going to lose a lot if I don't?

Act quick. Just release the psi and tighten cap.

Just a splash or 2.

 

[GTPpower]

Maybe a cup or two leaked out. Not bad at all.

Here's the old one.




I had to swap actuators because the vacuum fitting wasn't the same size on the new one.

 

[Rdrnnr]

Why does everything with Ford diesels have to revolve around the cooling systems. You ever tried this stuff man? In the idis adding scas is pretty necessary to keep bubbles off cylinder walls creating hot spots idk if it'd help here at all or if its somewhere in the 20 pages of all this already but it's instantly my first thought after reading into a couple pages anyway.
