03 OZ Clutch Problem

I'm having trouble and was wondering if anyone can help. I replaced the master cylinder, slave cylinder,and clutch kit back in December and now the hydraulic system wont hold pressure, When i bleed the system it feels fine but after about half an hour of driving it goes soft and doesn't disengage the clutch. So i brought it to the shop and the said it is the master so i replaced that and hasn't changed anything. I was wondering if anyone has encountered this problem and can give advice for what can be done to fix it.

OH and the parts are OEM not aftermarket

It sounds to me like air is getting into your system somewhere for sure.

Let's start with the stupid simple stuff and hope it's one of these.
1: You are closing the bleeder valve after you bleed the system?
2: You are filling the master up over the full line to make sure it fills the clutch side?
3: All your fittings in your clutch line starting at the master and going into the slave are tight?

Now for the hard stuff.
1: It could be a bad hose, small crack in the clutch hose.
2: Bad slave cylinder?
3: Bad break hose?

If it is any of these you should be able to find break fluid as evidence.
Are you loosing fluid at all?

bleeder valve is tight
brake fluid is filled past full line and is in the clutch side
all the fittings feel tight and doesnt look like any fluid leaking

going to check if hoses are cracked ill post what happens when im finished

thanks for the feed back

Update

Alright I believe its fixed, i went and rechecked everything and where the steel line screws into the slave cylinder was a little loose. so i tightened it up, bleed it and the pressure still dropped but this time it only went down to where it disengage/engages right on the floor. so i adjusted it out and now its staying at a good spot. so hopefully it keeps working.

Thanks for the help

update

ok so it worked fine for about a day or two. then the same thing happens. so i went to the dealership to get a flex hose and started talking to the guy there about it, and he said that the pressure plate that came with the clutch kit probably has to much pressure and its pushing the fluid back through the system. which sounds right because the other day after i bled the system and drove it there was more fluid in the resevoir.

I was wondering if anyone has had this problem.

I can't see how a pressure plate could be installed backwards, I don't think it's possible.
The clutch can be installed backwards for sure, but I forget what doing so does.
Perhaps someone else can answer that.

As for the fluid level raising;
Still sounds like air is getting into your system to me.
If air is introduced into an otherwise tight system, it'll displace the fluid.

Walk me through how you bled your system including how much fluid you removed after the last air bubble you saw.

When bleed it, i leave the clutch peddle all the way up, open the cap and bleeder valve on the slave, after no more bubbles come out i wait about 30 secs the close everything up.
