Does this happen to your A4? [Archive] - Official WDP Angel Owners Group

Upon gassing the marker and holding it near my ear, there is a minor hissing sound coming from around the LPR area? I tried soapy water to see if it would make bubbles, but there are none. So I am guessing this is normal. Or does it not happen to yours? The end cap is fine and so is the o-ring. The air is Crossfire LP 68/4500.

Also, after degassing, a minute later there is a whoosh of air that comes out of the marker. I also am assuming this is normal.

I finally used my A4 today and I was pretty impressed. I had some chops but I'm not sure if it was the paint. I was using the stock barrel and Marbs but was chopping a couple here and there. I think the paint may have been bad as it was a little cold outside and I accidentally left the paint in the garage overnight. I was on Semi 1 and yes I did the calibration. Drop test is a 40/40 pass rate. Dwell was at 12 and was using the largest volumizer. I am going to try Semi 3 to see if that helps. I am using a Y-Board Egg as well.

Overall it is a great marker and I cannot wait to play again. I am a n00b to Angels but not a n00b to paintball. If anyone can give me any advice besides what has been mostly covered in this forum that would be great.

The whoosh happens a minute after I unscrew my tank. It won't do it if it is still attached.

Well, at least I'm not crazy if you hear the hissing as well. I will assume that is normal operation. Either that or we are insane.

I had a hissing noise for a while when I first got the gun. After checking everything, I finally figured it out. The screw holding the grip frame to the marker (inside the trigger) was slightly loose. Tightened it up and all good to go.

I found out where it was coming from. If you look at the flash tank (what the minireg screws into), where it attaches to the body, on the left side there is a little divot/notch on the flash tank. There is a little hole on the body that emits air of some sort. I guess air is supposed to come out since the notch is there to give it some sort of exhaust port.

I'm not worrying about this since it obviously is part of WDP's design. It stumped me for a bit since I could eliminate the hiss if I placed my finger over the notch. Some soapy water and some bubbles later confirmed this. The removal of the flash tank allowed me to discover this hole, although a flashlight will allow you to see it as well.

Interesting.

If it is leaking from the notch in the flash tank manifold (1 piece now, 2 pieces prior) then you have a leak in the lpr.

It doesn't really sound like a leak. More of a controlled escape. It's very faint and can only hear it if you hold it up to your ear.

a leak is any release of air tho mpire, it doesn't have to be large, it's still a leak. Try replacing the LPR o-rings, or even just greasing them up or something.

Yeah I'll check it out. This worries me though since the gun was brand new and "checked out" by a authorized dealer/service center before it was sent out to me. There should be no leaks in a brand new marker.

I believe Moogle has this same problem, it turned out his lpr orings were causing it. He claimed they looked fine, but might have shrunk. Replace those and you should be good.

I'll attempt to fix this sometime this week. Such a bummer. Well at least I'll be able to fine tune the LPR pressure now. I guess since I was going to do it anyways then this really isn't a hassle. Thanks warpedx.

Well I have seem to have fixed the problem for now. What I discovered is that upon taking out the six shims that were in there, four of them have some sort of rust/residue on both sides of them. Keep in mind this is a brand new marker and was used for the first time on Saturday. I received it on Wednesday. I think this is what may have been causing the hiss/leak. The minute rust particles may have been causing the shims to be thicker than what they normally should be. I do not have the LPR gauge at the moment to test out the pressures beforehand and afterwards. My guess is that there was too much pressure in the LPR causing it to leak out.

I took the four out and replaced the four with the two extras that were in the parts kit included with the marker. I am now running four total (two perfect ones that came with marker, two perfect ones that came with parts kit) at the moment. I really need to get that LPR gauge to finely tune the marker, but at least I seem to have solved the issue with the hiss. I am not really satisfied at this point, but will do for the time being.

thats from using comperssed air and not nitrogen.if your fill operator is using a compressor,the water seperator may not be working properly.if this is the case you may want to oil more freq.

I'm not sure of the local shop and field's fill stations (they are both reputable though), but I'm pretty sure I received the marker this way. In my first post I discussed how I get a whooshing sound of air about a minute after I degas and unscrew my HPA. This happened when I first fired the marker at home before I visited the field.

Since "fixing" the shims there has been no whoosh. I'm pretty sure the whoosh and the hiss were directly correlated to the higher pressure in the LPR.

There was no way that it could have rusted that fast right after I shot it at my house when I first got it. I still believe I received it in this manner.

that is correct sir, the only difference though was, mine had a huge leak, his seams to be minor, but still, and his "solution" might be causing more problems(dropoff) instead of fixing them

I'm not sure I have any drop off problems. There seem to be none evident at the moment. I am waiting to get an LPR kit so I can precisely tune it. Most other members report taking out two of the six shims included without any problems. I know each gun is different but it seems much better now regardless.

I figured something was up when I was going through air quickly. It definitely wasn't efficient. I got maybe 500 shots on a full 68/4500 tank (local shop anf field doesn't fill to 4500, only 3000) before I filled it back up when there was around 800 left.

were you dry firing? that will seriously reduce the amount of shots you get per fill

No I was not. I only shot about 15-20 dry shots after putting oil in the minireg. This was after I played on Saturday though.

My marker does this as well.(Makes a suttle hiss) I am sure that it is the exhaust valve. I read something in the forum about it taking some time to seat properly.
HOW ABOUT EVERYONES SOLENOID ????
does your solenoid make a very rapid ticking sound when the marker is gassed? It is hard to hear but I am afraid it has a leak.
1 Sensi not functioning properly.
2 exhaust valve leaks
3 solenoid leaks
4 chops paint with sensi on regardless of hopper/paint type
did i mention my a4 is brand new?

I'll air my marker up tomorrow...someone might need to remind me tho...it's 10pm here, and I don't think my fiance would be too thrilled with me airing it up right now...however I have 0 leaks on my marker I know that for sure. I've been getting great efficiency outa my 4.

If you run a high pressure preset in to the A4 it might hiss

I'm running a LP Crossfire.

On a side note, I oiled the hell out of the o-ring on the Brass Piston and the leak seems to have stopped once more.

i am also running into most of your problems,
1 Sensi not functioning properly.
2 exhaust valve leaks ( mine doesnt any more, my local shop called wdp they said it had to be broken in for it to slowly fade away)
4 chops paint with sensi on regardless of hopper/paint type
did i mention my a4 is brand new?

i am bitter about owning a 1300.00 dollar paint blender, well i expect paying thjis much to own a gun that wont chop......i constantly am getting pauses with my sensi on, i now have a feeling my sensi is giving me a prob....it will read the first two balls droped, skip 3 then read a few more, and etc.....

:lost:

Guicho

12-01-2003, 05:30 PM

i forgto to mention, had a halo, switched to egg made a hell of a difference in the amount of chops.....1 chop every 300 or 400 balls......really it improoved but i want no chops, but if i run it on sensi it blows....skip shots, but if i put in semi3 it chops eventually, i lowered the Mrof to 15bps, and still chops.....also my gun has no shimms at the piston, that is the way it came, i have 2 in the baggie of xtras, but i figured it didnt need it, considering the low pressure im trying to acheive.. i dont have the tool kit, but playing by ear, with help of you guys......and i am using kens settings, my gun is not doing its best . skips on sensi.. i have adjusted the trigger correctly too. my Tr is at 5 dwell 17 mrof 15

and by the crappy mini reg gauge, i am about 290... ( chrono read 285- 290) pretty consistently...any one down to help a brother out.

Your going to need to find out what your LPR is set at.

Emmit, did you ever test to see if your solenoid makes noise?

take the oring off of your LPR and make sure there are no brass shavings on the LPR. I had the same problem with my speed. It would have a very slight hiss and then once i oiled it, it would go away. I cleaned the LPR and replaced the o-ring and it is sealed as tight as a drum.

Yeah. I fixed it before. It was the o-ring on the brass piston. I oiled it up and it's been working fine since. Thanks for the help.

Please, anyone with an A4 do a test for me. Gas up your marker as if to play a game and listen to the solenoid to see if it is making a noise. Mine makes a very rapid ticking sound that resembles a solenoid leak. It is hard to hear but apparent if I hold the gun next to my head.
