Travis,
I have started having issues out of my 3rd function valve. The allen head plugs on the sides of the valve have started coming loose randomly and leaking fluid all over the place. I've tightened them several times, and tightened to the point I fear I should tighten no farther, but they still come loose and leak.
I haven't taken them out to know if there is any sort of o-ring or seal in behind them that might need replaced, I thought you may be able to tell me? Otherwise, I wanted your recommendation on what sort of thread sealer to use to prevent them from coming loose? Am I being silly to worry about over-tightening them and should just crank em down?
Thoughts? Recommendations?
Thanks, and have a great weekend!
I have had the same thing happen several times and I posted the issue on this forum... At first I thought the allen screws might be PSI adjustments but apparently not... I do not see what purpose they serve other than possible a pilot-operated device or gauge... I was told by the OEM and Dealer to simply tighten them as much as possible... That stopped the leaks BUT they have since come loose again... I have NOT done this yet but I am about to try some Teflon tape or LockTite... LMK how this plays-out for you and I will do the same...
