No symptoms at all, I’ve just seen the aftermath of DI and new it was in my best interest to clean the intake valves out sooner rather than later. Also prepping for turbo upgrade so it was on the todo list.Wow, big improvement! Were there any obvious symptoms/issues or was it just a good time to do it? Did you notice an improvement afterwards?
This was cleaned using a combination of scraping with pick tools and also using a walnut media blaster. Which is what I’d recommend for anyone looking to clean their intake valves.Was this a media blast clean or soak and scrub method? Are there any issues with using the soak and clean method, for instance if the some of valve cleaning solution gets past the valves. Could that be a problem? I only ask because I thought I read somewhere that it could happen and maybe has some adverse effects.
