Hey guys, I've got a 1953 Pontiac with a flathead 8. I want 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 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 put a muffler on it. After running the car and letting
it suck in sand we got about half way through a 25 lb bag. 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 Pontiacs.


any ideas??

Reminds me of a guy on a US Mustang forum who ,when told to top up the water, filled his engine up with water via the oil filler cap - that was true though :wacky: ..... as I remember he was subject to quite a bit of piss taking by his peers :lol:

Saw this years ago on an Audi forum. I bet someone, somewhere has tried it though :eek:

as you may know, the yellow dye comes out of the builders sand which we thought might damage the engine, so we used play sand as that is generally cleaner. :lol:

Just make sure you do use the correct type of sand.It must be pure sand with nothing added,such as cement.This is a commonly used additive for sand and used in large ammounts creates an all together different material called mortar.If put in your engine it will set causing the engine to stop going round,or seize.
