Carbon On Intake Valves

I decided to try my hand at carbon cleaning with walnut blasting media. It worked great and didn‘t cost much to get started. Like anything I had my apprehension before actually doing it, but I’m glad I decided to give it a try. Here are some photos of my setup and results.

Your results are remarkable. Is there carbon build up on the valve seats also? Is that another procedure?

I did find that things go faster and better if you do a little scraping and cleaning with a thin screwdriver or pick to knock things loose. I used a right angle pick to clean the area where the valve meets the seat. I couldn’t actually see the area where the valve touches the seat. An additional chemical cleaning such as an induction service might not be a bad idea to clean the contacting…

Where did you buy your set up? Mainly the gun for the blasting. I have a set up but we are not happy with the nozzle handle for shooting the media. HA! Zoom is helpful, "the original sandy jet" I'll start googling. Great results!

I bought the Sandy Jet F-90 off of Facebook Marketplace for $60. The nozzle was worn out so I replaced it. I taped a piece of straight radiator hose (about 3 “) to the shop vac hose that I put a hole in for the nozzle. I varied the position of the nozzle, sometimes on top, sometimes on the sides. The hose does a good job sealing against the head surface.

Nice job! Creative way using shop vac. I have used my Motorvac as a maintenance but haven't taken pictures of before and after.

Just buy the oem adapters for the shop vac. They are cheap at least from BMW for their cars they are.
