how NOT to port and polish a head

[zoom zoom]

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.

I thought YOU were doing this!

"Use quotes next time," as well as alerting us that you are getting it from somewhere else, like this:

I found this on xx.net:

"Blahblahblah blah blah."

Ain't that stoopit?

I wouldn't worry about it. Those sounds are normal for an Audi. I should know...
My wife's nephew's gilrfriend's brother is going to school to be a VW/Porsche/Audi mechanic.

You might try sticking a garden hose into the intake to flush it out. I read on the internet that some guy did that with good results.

Actually the sounds it is making are caused by the sand that made it through the engine and is now in the exhaust side of the turbo. Need to immediately disconnect the downpipe and run a pipe from the turbo's exhaust outlet back up to the intake so the intake can suck the sand out of the turbo.

LOL I got half way thru this and was like.... NO HE DIDN'T !
I had an instructor in A&P School who was a certified inspector & stunt pilot.He also raced circle track.He would love to mess with us.One day on break he bet us that we couldnt drown out his pickup with a garden hose. We didnt know that he had already done this many times. He had an old beater for a daily driver.Pick up with a 454.We got a garden hose & he held the throttle almost wide open.Garden hose blasting right down the carb.I thought surely its gonna puke in @ 10 seconds.It never stalled. And he drove it to school the next day.So I guess we couldnt have hurt it to much :eeeeeek:

Might as well pull the engine and throw it away. This is what happens when you believe all the BS on the internet!!!
