Hey guys, I've got a 97 ford f-250. I've had a 14.7k mod… for a while and wanted to get more performance. I 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 dirtymaxes 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 floor 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 manifold.
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 dirtymaxes so he doesn't know much about fords.
I take out the air filter, fill the area with sand, put the cover back on, then start the engine. You should never add sand while it's running, always add then start. Also, always use 80 grit or courser.
Well, lets see if I got this right, you started your truck and poured sand into the intake while the truck was running and keep doing it until it quit.
Air filters are there for a reason, TO KEEP DIRT OUT!!!!!
So,
1. You probably destroyed your turbo (any air that goes into the engine goes through the turbo).
2. You probably sand blasted (read "destroyed") the nozzles of all of your injectors.
3. You probably put so much grit in the cylinders that you scored the walls and erroded the rings.
4. You probably have a build up of melted sand (read "glass") sitting in the cylinders, and stuck to the top of the pistons.
5. The list goes on and on.
Now, WHAT IN THE HE!! WERE YOU THINKING!!!!!!!
Sorry, but you have probably toasted your engine for good.
If i was you i would pick her up and have her add more sand to it while you hold it to the floor. If that doesnt work just put a brick on the gas and walk away! Good Luck

If you hear noise coming from the exhaust pipe...DO Not look in the pipe to see what's making the noise unless you are wearing safety glasses.
