Hey guys, I've got a 98 1.8T. I've had a k04 and chip 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 Hondas and we decided to try it ourselves. We got a bag of sandblasting sand and hooked up into the intake and started the car. We had to hold the gas 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 ehxaust 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 car 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 car 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 Audis.
your friend is a total duschbag, yes they pump sand through the manifold to polish it but it is done OFF the car and the sand is WET not dry. your friend caused u to suck a ****load of debris that got sucked into not only the manifold but into your valves, and so on. i bet none of that actually made it out the exhaust. u got 1.8l of sand in there. your engine's basically gone.
my only hope is like scott said, this has got to be a joke. if so i got a joke for you too!
return everything back to stock and take it to your dealer, see if they'll fix it under warrenty =) (i hope most of you get this)
