E4od dead!?
I believe it is the pressure accumulator control valve piston hanging up in the bore. It can be bored oversized and replaced with an oversized piston. This is my hope. this is a really simple and cheap fix, I don’t even have to take out the trans just the valve body. This is all academic as I...- Dedward

E4od dead!?
I had replaced cracked heads on my 90 7.3l with a E4od and a banks sidewinder several months ago. Found the engine a bit worn and so had just been using it out in the hills where I live for firewood and such. tuning it up and getting things ironed out. I had gotten it to drive and shift fairly...- Dedward

Coked injectors
Those are some coked up injectors. I ran WVO in my 6.2 for years and never had that much coke. (I only briefly ran wmo ) The different injectors in the 7.3 are for NA versus turbo, the pop pressure is higher. You could rebuild them and add shim washers but they have to be “balanced” pretty well...- Dedward

Looks like mouse nibbled pistons ?
Ah anodized, ceramic is interesting if really trying to push limits tho. I was thinking just that about the 6.9 coolant mod but had ordered factory head gaskets already and the 6.9 have a triangular rubber coated gasket seal that I figured mattered with the coolant contact. So I wussed out and...- Dedward

It’s the whole left bank of cylinders. I’m pretty sure more fuel makes a lower temp while lean burning makes higher temps. Turbos burn hotter because they create a more dense fuel air (more air/leaner) mixture, a bigger hotter charge per power stroke and that heats up the whole area beyond...- Dedward

No it’s not the factory turbo which I believe have ceramic coated pistons and larger wrist pins. So the damage is obviously a result of the added banks turbo. But they shortened the life span of these right off the bat by closing off four coolant passages. Probably cost the engines 100000 miles...- Dedward

Thanks u2slow. That + the cracked head makes sense. It came with a banks and based on the overall wear in the engine the po drove it like he stole it. Probably never even glanced at the egt’s. super disappointed by my experience with the 7.3. Looking for a 6.9 that I can swap parts and lightly...- Dedward

Has anyone seen this? All the pistons on the left bank have the same nibbled top of the piston, right side is normal. I Pulled the heads because of blown head gasket and found cracks between two valves on this side. Also all cylinders have obvious lobbing. I am just going to throw the gaskets...- Dedward
