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

 

Most GOOD kits do

 

No kit that iv seen has one it's extra

 

Snow doesn't, Devils own doesn't, idk about aem. Every one iv seen u have to buy it extra. Devils own has the best one iv tried. That is right though solenoid isn't required just check valve

 

That is so weird, because this Snow kit does

 

And apparently every Snow kit comes with a check valve.

 

they must have changed that or u got a different kit than I got.

 

they definitely changed that since I got mine, well guess I'm wrong lol

 

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.

 

Nvm

 

Nathan's valve 30 to 40,000kms he runs a lot of meth but he also had a PCV failure

 

So meth does not help much with coke valves...

 

Nathan claims that it was burning oil pretty bad before he changed the PCV. The head that is on my car now is easily the worst I've seen so far but I do not know if he had meth or not

 

If you have ever tried to remove the coke from a valve, its very hard to get off. I think the only time meth would be of any help is if you started with a clean valve and used it very often.

 

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

 

what were your results for keeping valves clean, i am considering run a set up for valve cleaning purposes

 

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?

 

I am using this now to run cleaner and water through my intake. Works great.
i am however pulling off the manifold to do a manual cleaning tomorrow. First thing i am doing for 2021 lol
