I replaced my engine recently, when I was lowering my motor it slid nicely onto the tranny input shaft. It was off by maybe a 1/4" so I jiggled the tranny and it lined up. I bolted everything down. I bled my clutch twice and still no clutch. I took off my slave cylinder and noticed it was frozen from rust. I bought a replacement today, installed it, bled it twice and it helped a little bit. what I mean by that is on the old slave you could only get the pedal down 75% of the way and it would stay there. Now on the new slave the pedal goes all the way down but comes back up about 35%. I have a new SS clutch line, and new slave cylinder.

Something I noticed that was odd.
I would bleed the the air out of the clutch by closing the valve, pulling the pedal up, opening the valve and pushing the pedal down. During this process the clutch draws fluid from the resevior. When I do the other bleed process of opening the valve, hooking a line to the valve and then pumping the clutch the system does NOT draw ANY fluid from the resevior, BUT on my old slave cylinder it would.

Now the tranny fork...Should I be able to move the fork foward by hand at all? Because I cannot. I do not know if you should be able to move the fork at all. But I was thinking maybe when I slid the engine and tranny together that somehow the fork is wedged or something like that.

Anyone have any suggestions?

Thanks in advance.

If you're worried that your master-cylinder is not "draining" it's fluid, simply open up the bleeder-screw on the slave cylinder and then start pumping your pedal like mad. You'll find out real quick whether or not it's "sucking" from the master or not. It'll either start spitting air, or you'll have a small mess in the engine-bay.

If you can get the resevoir to drain, then you're on the right track (because that means fluid is actually circulating).

I think it'd be difficult to move the clutch-fork by hand, but then again that's just a guess. Also, there's not a *lot* that can go wrong when mating the engine and tranny.

Just make sure fluid is pumping out of the master-cylinder and coming out of the bleeder-valve. Once you've checked that off, then just re-bleed the clutch with the help of a buddy. Have him pump the pedal like 10 times in the attempt to build pressure, then while he's pushing down on the (pressurized) pedal, release the valve and then tighten it back up again. Do this several times after you've done 'your' method several times. You also might try cracking the line at the top of the master-cylinder, and bleeding it from there a couple times--just to cover all your bases. I dunno, just a little imput.

Well it does drain, when I do this process:

Closed nipple
Pull pedal from floor
Open nipple
Push pedal

That process drains the master cylinder but if I do this:

Bleeder screw open
Line on bleed screw into brake fluid
Pump clutch 25 times
Not a bit of fluid pulled from the resevior.

This pisses me off so bad, my clutch was working fine before I swapped engines. But also the car sat for over a year.

I was supposed to move to L.A. on monday, if i can't fix it by the weekend I HAVE to sell the car.

ok if the clutch pedal sucks down to the floor and you hear bubbles in the master cylinder then you have a torn bushing in either the clutch master cylinder of the clutch slave cylinder. and they need to be replaced or rebuilt. it is easier to buy them new but alot cheaper to reuild them.

here is my link on how to rebuilt the clutch master and slave cylinder. it shouldnt cost you anymore than maybe 2 hours of your time and no more than 25 bucks total

If I hear the bubbles? Won't that be hard to hear? The slave is brand new and the SS line has less than 3000 miles on it. I am going to re-bleed the clutch, getting all the air out of it. If I have to I will rebuild the master as well.

Anything thoughts on the tranny fork? I need someone to watch the slave to see if it moves when I push the clutch. I need to make a friend in my parents neighborhood. This sucks because of time, I have a lease in L.A., I'm supposed to be there ASAP!!

It's not the hydraulics. The slave pushes the fork. But when the car is running it does not shift into gears. It's gotta be the either the Throw-out Bearing. Pilot Bearing. Or Pivot Ball. Right?
