FX Impact X Slow Leak

Good evening,

I recently upgraded my Impact X to the MK2 but upgrading the parts. I’ve let the gun sit for two days and it’s lost about 10bar. I was going to begin trouble shooting but when I removed the CF bottle, I noticed that the gauge on the gun didn’t immediately go to 0 bar. It almost took it two minutes for the gauge to get to zero after the removal of the CF bottle. This has never happened before so I’m not sure where to begin. 


Any help is greatly appreciated. 
 
Don’t use soap, it contains salt, it is also very searching, any that seeps around a thread will cause corrosion (I have lost count of the amount o seized screws I have removed from guns) . Save yourself a load of grief and buy something like this

The thing with the last remaining air is normal. Some shoot the gun one time to clear that last bit of air but I don't advise it. I'd suggest you just turn the regulator adjustment a little and the air will escape harmlessly. I don't know what you added or did to your gun parts wise but I know lots of people have problems after adding an external plenum because they tighten it too much or not enough. The little delrin washer doesn't need a whole lot of pressure to seal. Of course, it could also be the valve, valve housing o-rings, gauge o-ring or many other things depending on what you did to the gun. Bob's advice is spot on, use soapy water, detecta-leak or something similar to find the leak. If you dry the gun thoroughly after working on it, soapy water shouldn't be a problem if that's all you have. Ernest even recommended I dunk the whole rear of the gun in a bucket of water one time. As long as you clean and dry it, no worries! It can be intimidating to work on the Impact the first couple of times you take it apart but it is definitely not hard. After you do it once or twice and get comfortable, it will become second nature which will benefit you in the long run anytime you need to do maintenance, change O-rings or fix something else. Good luck.

Hi stoti,

I changed the valve to MKII and i notice, for the first time, there is a protruding round metal inside the block where the valve is inserted. It was a littler harder to insert the valve but i ignored it as if it is normal. I also replaced the gauge but i am pretty sure it was just a hand tight knowing what Ernest was saying before hand. I have no external plenum. I don't intend to get one. That is why i just bought the MKii valve and valve tube because it is just plug and play. But when a leak was coming from the base of the gauge, i was afraid to tighten it because of Ernest's advise. Upon closer inspection, the washer seems to have been pressed that tight. The way it was pressed, it looks like it was torque pretty tight. I thought that if i will tighten it more to prevent the leak, i could damage the block. So, the oring that came with the huma gauge could be a better option because it is soft unlike the silicon ring or delrin. Luckily, it seals perfectly until now. But how long will that protruding metal in the block stay fitted. The air is holding well even after a week. The pressure gauge for the bottle (not the regulated) did not move AT ALL. Yes, perfect.

Turning the reg counter is my way of releasing the air from the valve tube. 

It was intimidating to take it apart unless you have watch hours, days, weeks, and months of youtube on "how to do" and especially when you have waited for 8 months (!) for the gun to arrive just like mine. The replacement o rings, compressors, pellets, etc came first before the gun. NOt complaining though. I am happy with the gun.
