LNF coked valves vs meth

what? most kits have a check valve built into the nozzle holder, you need to reach the set cracking pressure before anything flows out of that nozzle

i know both my aem kits had a check valve included but i have no experience with other manufacturers. I didnt want to damage my stock charge pipe so i drilled out the silicone coupler and installed a bulkhead fitting 2-3 inches away from the TB. great location for servicing or changing out nozzles as its really easy to get to but hidden out of plain sight.

Well I can actually test this out I have clean valves I installed last summer and ran meth the whole time so when I take off my intake manifold again I'll try to get some pics

Here's my way of dealing with valve coking or contain it to the minimum.
Had used it only twice in the summer but I will be using it every other oil change at 4k miles.
I would first empty my CRC turbo and valve cleaner in the reservoir. The switch/valve would control the proper amount of cleaner entering the intake. I've made a bracket to lock the gas pedal as per instruction to have the engine rev at 2k. Works well. I would do a few more cleanings before checking the valve with the scope.
Ideally use this right after your valve has been walnut blasted so to prevent the build up. It would be difficult to clean them once the carbon has the chance to baked on to the valves?
