wait, so how does my 86 have an external slave? There was a code somewhere on the jeep that made me think it might have had a t5 at some point.... but now it's an ax-5...

Still, I'm having the same random loss of pressure thing, when I get the an un-broken engine I'll get a new slave cylinder too...

Because, most people forget or don't know the early XJ/MJ's had external slaves as well.  That stopped in '87 when everything went internal.  Before the TJ's, a common swap was to use an early XJ bellhousing to convert the YJ to an external setup.

Ha, wow... that seems kinda backwards! Either way, I'm having major troubles with pressure loss... to the point where it is unbearable! It seems completely random, too... no pattern to it at all... I'll replace the slave soon in any case...

I think the reason for my problems was that where the line for bleeding the system leaves the bell housing, it looks like there should be a rubber grommet to hold the line in place. this lead to the lien vibrating loose and then when we bleed it it worsened the situation causing it to eventually totally come out of the slave cylinder. so now we have made a rubber grommet to hold it in place and after bleeding it it has worked great... now if i could find some time to find that vacuum leak...

Mine is external, so I don't imagine it's anything like yours as far as mounting goes...

I thought for the longest time that mine had a vaccuum leak (and it did), so I replaced ALL of my vac lines... it worked for like two days, then the high idle came back... I started chasing sensors and it turned out to be my TPS and Idle control motor, but I couldn't find either for anything more than an arm and a leg and just about everything else was getting way old too... So I decided to start gathering parts for an MPI conversion... too much money later and lots and lots of parts; I still haven't started.

Totally not worth it IMO... I should have just bought a different jeep. I let way too many opportunities pass, but I'm too far in to turn back in any case; might as well finish and put this on my *never again* list!

Good luck to you!

I have been daily driving the jeep for a week now and this problem is back. its a 15 mile out - 17 mile back  commute and in the morning clutch pedal will be nice and firm through and through. but on the way home it will start off good but at the last traffic light (mile from home) it losses half its usable travel. still has enough to disengage the clutch but it is bringing back bad memories. The commute is mainly freeway driving except for 4 traffic lights at the beginning and end of the trip.   :brick: :guns:.. its like clock work same every day. no loss of fluid. perhaps i need to bleed it again.  :deadhorse:
