You verified you have flow through the heater with a garden hose and the in/out was hot? Stop leak a PO used (or customer) clogging the core? What exact problems did this engine/vehicle have before you started the repairs? Generally the intake leak is a problem by itself but low coolant could...

Clearly you have a problem in the rear head area or block. Pictures you posted do not help. You need the entire rear head gasket examined both sides. If you don't see where coolant or carbon was tracking, yes, look for cracks. Including cracks past the valve seat into the runners on the head...

Thanks @Big T Nice to be validated (along with others who worked on the ATT in it's day) starting around 16 min. 21 Min IS the "lag" where you need RPM for the turbo to light off. 23:40 Mr. Banks with a loose converter and Big Turbo. 🤪 Where have we seen this on say a 6.2 IDI Turbo Two...

No. Primitive Artificial Stupidity computer is programmed to ignore intermittent problems to reduce warranty claims and difficult to track down problems. If you have TWO Volts across the two glow plug terminals when it's on, and you need to check exactly this, then it's a problem: loose...

Do you have 2.X Volts across the controller when it's on? Indicates a high resistance in the controller or bad connection at it if so.

Guessing 3.1L or 3.8L V6? They are known to leak coolant into the engine from an intake leak and lock the engine up. The reason they have the gasket (pictured) is because of the cast iron and aluminum expansion rate difference: gasket allows some movement. Have you checked price and...

I would sample the engine oil looking for diesel in the oil in case the fuel pump diaphragm is leaking. IMO It's simply sitting too long without running. Air leaks you won't ever find due to how slow they are leaking is likely your cause. Now if it's an overnight air in fuel system then you...

Err, Well, No. Grid Heater Bolt. When it gets loose and the bolt burns in half from the arcing ... the engine eats it. Rare but happens. It's a risk on my 2018. The newer RAM Cummins models just burn the truck down from a now recalled grid heater relay. :facepalm:

Again a picture is worth 1,000 words. A video with sound eliminates strange words used to describe sounds. Best attempt ever made to put sounds to words was MAD Magazine. Otherwise we are down to "a funny noise" Could be nothing to worry about or can get real expensive. Even with video I find...

I time mine by ear. Warmed up engine at 45 MPH. Go from no throttle to some throttle. The IDI clatter should go away as you get into the throttle and the precups heat up. Too much advance causes a rust like texture of erosion on the glow plugs. Altitude also affects these engines and you may...

Video a startup. Someone at the exhaust pipe. Post on youtube and link here. I suspect you have a long cranking time and thus air in the fuel system. I see repairs been made and this can cause the old fuel lines to leak air. Return lines leaking air can allow the system to drain back to the...

Normally without the engine "loading up" and making you stomp the brakes harder? If so I suggest you start with engine not running well. Low fuel pressure and my favorite is a sticking EGR for a PIA to troubleshoot because to avoid warranty claims (and nuisance) with slow primitive ECM's there...

Sounds like the EGR is sticking open. More throttle allows the engine to run with unexpected high EGR vs. run badly at idle. You have done the pop the transmission into Neutral when it's acting up to help eliminate or confirm the sticking TCC theory. This "Unloads" the engine even if the TCC is...

@jrsavoie It's pretty clear... EPA Administrator Michael Regan said “vulnerable communities are more likely to reside near highways where these harmful emissions are concentrated, making this agreement critical to advancing our environmental justice agenda.”...

If you are subject to migraines or seizures the strobe type LED's are a real weapon turned loose by the cheap lighting industry. I suggest it's a weapon of war sent in by China to disable Americans, but, more likely American's cheap willfully ignorant arrogance. Add Commiefornia's lets have a...

Best laugh I've had all day. 🤪 Even with the wick turned up (spool valve, huge ATT turbo, insane EGT tune) at least mine didn't come in dead last on dyno days as because a stock 7.3 IDI was strapped to the rollers at some point...

I had to go out and look at what I have leftover I picked up at a local hot rod shop: lopersperformancecenter Made In USA... Best example, via a kit, of what I used. Paint, stainless steel tie wraps, and the actual wrap, you need lots of those tie wraps: Thermo-Tec Exhaust Insulating Wrap...

Header wrap it past the passenger floor pan. Header wrap on the manifolds. (Best done with manifolds removed.) Turbo blanket. All painted with the header wrap paint to reduce moisture and harden it in place. When you ain't scared of 1550 EGT it helps things not melt in the area and the floor...

Drop a hot water heater and it cracks/breaks the glass lining on the inside of the tank. I don't know if they are all glass lined inside the tank anymore. So scratch and dent is garbage with the extreme risk of future early failure and flooding from rust in the now unprotected area. A flood from...
