Thinking about using the CRC intake valve and turbo cleaner on my 2021 Chevy Silverado 1500 with the 2.7L turbo engine. Vehicle has 20,000 miles on it and I have no issues. Just wanting to do this as preventive maintenance. My MAF sensor is right after the air filter. A little further down the air tube is where the PCV valve is piped in. Here's my question...if I unplug the PCV valve and inject the cleaner in that port, will the PCV valve still vent the crankcase to atmosphere while it's unplugged during this process? Or will I build pressure in the crankcase that could be problematic before I can even finish the process? Thanks for any input!
You don't need any snake oils or cleaners for a 2 year old truck, and they certainly aren't part of "preventive maintenance".
Stick to what you see in the owner's manual.
