I can hear and see it going down but no leaks I tighten up all the fitting front and in the trunk on the pump do you think I need to change the hose going from the trunk to the front man I don't know why it is going down can anyone think of why this could be happening maybe the hoses are old I got new hoses but I just don't know when it goes down I can feel it on the hose when I grab the hose I feel a thump but it is probably from the vibration help! :uh:

try to shut your slow down valve. If the front dont move then clean or replace your checkvalve. It does not take much to jam a common checkvalve and then it stays open thus letting fluid through.

You mean if he closes the slow down and the car still drops then it's the checkvalve. If it stays up then it's in the dump! ;) Get it right homie. handing out bad info. :biggrin: j/p.

does not have to do with ageing, it just takes a small metal fragment to block the valve so it does not function properly. One of my homies discovered several metal flakes in his brand new tank from a well known supplier so it is probably a good idea to blow em clean with compressed air before fitting.

no 2, under the dump. As homie said, be sure to check wich way it goes. Fits both ways but work only one way.
cool I think there is a arrow on the checkvale pointing down so I am going to break the dump down and get the checkvalve off how should I clean it I have a compressor should I blow it out like that?

It may very well just need that, if that doesnt work remove the small retainer clip carefully and take it apart. It is a spring loaded ball that when pressurized lets trough the oil. Maybe the spring gets fatigued and need some stretch also if the problem consists...Im told you can just stretch them out but better get another opinion on that since I never had to do it myself.

yes it would............. now pull it completely off the dump ( remembering wich way the ball faces ) and push the ball in again blowing it out with air. clean it verry well, then reinstall.
it takes the SMALLEST peice of teflon or metal chip to get it NOT to close, and that will drop the car back down.


good luck. cool seeing someone doin it shit "live"

Man it is tough because I am holding the top of the dump with vise grips and using plyers to hold the checkvalve and it is hard to get a grip so it will be a minute I'll keep you posted :cool:
