Another outstanding video man! 👍👍 I recently performed the manual intake valve cleaning on a Mazda CX-7 and it was a pain! I used the same CRC Intake Valve cleaner you pictured in the video and it kinda works. Brake cleaner also kinda works. I ended up bending some wires into hooks and using some of those engine cleaning brushes to manually scrape it out. It was so bad the cleaner would leak into the cylinders because the intake valves couldn't close properly. I pulled the spark plugs and vacuumed out the cylinders. It probably took 8 hours of scraping. 💀Although, after I finished, the owner said "It's like the car is young again" 😂That reminds me I need to put catch cans on my Kia Stinger...

@d4a And with what Audi techs charge by the hour, I'm sure the owner felt the pain too! 😂

@deciplesteve From what I've seen the walnut blast and all of the equipment is also pretty involved, but I agree! Doing it manually SUCKS.

@SkylineFTW97 Yeah same engine. I had to replace the fuel rail and got one from a 'Speed 3 part out. I previously had a 2012 'Speed 3 (thus the name) and after doing the CX-7 I'm glad I got rid of it. (It was a really fun car tho. Legendary understeer.)
