Anyone got any tips on removing carbon from a 7.3's combustion chambers?

 

Get a 10k trailer behind your truck. Full throttle from a dead stop to 70 MPH a few times should clean it out.

 

Never never never never never never use any type of "cleaning" products in a 7.3L. That's the worst thing you can do to the engine. Anything that goes in the oil will cause problems. The reason is the 7.3L uses high oil pressure to actuate the injectors. Any cleaning solution will only aerate the oil and cause drivability issues. Anything that goes in the fuel will only be harmful to the injectors, since nearly all cleaners will strip away fuel lubricity.

Just do normal maintenance, and your engine will be just fine.

 

Got to run oil burners hard to keep them running good. Redford's advice and Pockets should be followed!

 

With the kind of compression the 7.3L is running, I doubt you have any real deposits any way. The heat and pressure in there will auto-ignite any carbon deposits.

 

What makes you believe it has a carbon problem?

 

is it a powerstroke or an idi?

 

I'd go further and say "never use cleaning products in ANY engine"

 

OK, just have to do this....

Hey guys, please help. My mod's gone wrong...

I've got a 2000 7.3, and I've always wanted to get more performance. It was recommended to port and polish the intake and exhaust. We found out they used abrasive material to do it like gritty sand. So I got with my friend that tunes Hondas and we decided to try it ourselves. We got a bag of sandblasting sand and hooked up into the intake and started the truck. We had to hold the accelerator pedal so it would run. He wanted to let the engine suck in the sand through the intake so it would port it out and then push it out the exhaust so it would port the exhaust manifolds and turbo hot section.

I was worried that it might cause problems but he figured it'd be OK as long as we didn't make boost and it get sucked in the turbo. After running the truck and letting it suck in sand we got about half way through a 25 lb bag. The check engine light was on and the engine was bucking and kicking and sounding really weird. We stopped and hooked the truck back up normal and took off the sand supply. We tried to start it again and it was really hard. Once started it couldn't idle and kept making weird noises. We took it out and drove it and it started to make scraping and knocking noises.

Help! Can anyone tell me what to do! My buddy only does Hondas so he doesn't know much about Ford diesel trucks.

Do you know if you can really shot peen the rods by putting steel (NOT lead) bird shot in the oil? The same friend told me he's heard of this working, too.

Shoot, you'd get a valve job out of that also! Too cool!

 

To SpringerPop:

Your friend is an idiot.

Being used to Honda's and aluminum engines, he probably had you use aluminum oxide abrasive. That is NOT compatible with a cast iron engine like your truck. You should have used a silica based abrasive. After all, that is what they cast the iron block in, so it is clearly compatible.

From your description, it sounds like you have plugged up the cat. Take it off, throw it away, and install a straight pipe with an 8" diameter exhaust tip.

 

Um, I'm pretty sure that was sarcasm directed at the OP

 

Some people have seriously defective sarcasm detectors. This is why Microsoft has spent hundreds of research dollars in the development of the SARCASM FONT.

The deployment is 3 years behind schedule as no one on the research team can take the font seriously.

 

I've had excellent results with this stuff:
Engine Scrub [ESCRB1] - $9.99 : KaleCoAuto, Hard to find automotive items!

 

That stuff is awesome!

I just bought some of their Cross-Drilled Brake lines too! They keep my brake fluid clean and cool!

In all seriousness, this is the way to do it.

Don't use any cleaning additives in your oil as they all are solvents and destroy the lubricating qualities of oil.
