If I use an intake valve cleaner that dislodges chunks of carbon from the intake valves or piston head, and they flow through to the exhaust, could they harm the catalytic converter?
I'm interested in testing the efficacy of intake valve cleaners by inspecting the intake valves before and after using the product. The carbon buildup is mostly on the intake valves in my direct injection car. I'm concerned that the dislodged debris could cause harm down the exhaust line since they could be relatively large for a system designed for gases.
I've thought of a few options:
- This isn't actually an issue
- Take off the exhaust before the cat or redirect it temporarily
- Put a temporary, high flow air filter at the exhaust between the engine block and the cat.
In number 2, would the reduction in exhaust resistance be OK?
Number 3 would be very interesting to me to see how much debris was removed. Some special air filters may be able to handle the high exhaust temperatures.
Any suggestions? Thanks!
