jonathan909 Posted December 18, 2018 Share Posted December 18, 2018 I'm happy with the progress on my (EJ25D) block, now it's time for the heads. I don't know what the best way is to clean carbon buildup from the valves, and googling the question just turns up endless spray-this-crap-into-your-intake links. Wire wheel? My old dip tank of Gunk carb cleaner? Ultrasonic cleaner? Combination of the above? Other? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted December 18, 2018 Share Posted December 18, 2018 Wire wheel works. Pull the valves and detail them. Or just leave them be. Not much benefit to cleaning them. GD 1 Quote Link to comment Share on other sites More sharing options...
Crazyeights Posted December 18, 2018 Share Posted December 18, 2018 (edited) +1 I remove them and clean them with a wire wheel if they need it. Edited December 18, 2018 by Crazyeights Quote Link to comment Share on other sites More sharing options...
