Ok, there's a lot of mention of carbon build-up on intake port and valves.... what about the exhaust valves ?
Personally my own engine, the intake side was fine (port injection), but was shocked at the carbon build-up on the exhaust valves... the carbon build-up from the hot exhaust gas actually look like grey rock that solidified on the metal |

QUOTE(AllnGap @ Mar 21 2019, 02:37 PM) Modern engine recirculates exhaust and have lots of catalytic mesh that could block exhaust if never service for sometime. Conlanfirm seafoam or whatever similar products cannot clean the build up i saw.If u were sprinting, I block one of your nostrils could u run fast ? No couldn't. I've personally tried seafoam and it works. can try that as an option before asking mechanics to clean it cuz it's usually not just a single part that got clogged. Intake, egr valves and diesel engine exhaust usually get clogged up. Need to remove the valve and grind it off. My car with the build up don't have EGR system |
