So this past w/e I cleaned her up after letting her sit for the past few months and it started right up. I went to put it into gear and it would not go. I bleed out the clutch and still nothing. It seems as though the clutch it frozen and will not release. I tried to start it in gear and it would crawl on the starter just trying to get it to free up. NE1 with some advice????

never heard of a clutch freezing...maybe the slave is bad

1) Start it in neutral. Get it good and warmed up.

2) Place the car in a position where it is not pointed and anyone or anything.

3) Place the car in first gear.

4) Start the car.

5) While the car is moving in first, put the clutch pedal in and vary between full on the gas and full off the gas until the engine breaks the clutch free.

Check the clutch hydraulics before performing the above suggestion. If either the slave or the master has lost their ability to hold pressure - the clutch disc will be engaged full-time.

How does the clutch pedal feel? Little to no resistance (other than the spring on the pedal)?

I tried to bleed the system, got a nice smooth flow of fluid no bubbles. The pedal feels as it did when i bought it which is on the light side. I see no fluid on the outside of the lines. what could have caussed this it was fine the last time i drove it @ 2-3 mo ago never had a problem???

Go to the bell housing inspection hole and with a screwdriver move the clutch fork back and forth. This will isolate the problem. If it does not move it is an internal clutch problem.

If the clutch fork moves....

Unless you had coolant from the top of the engine----heater control valve leaking or the short hose above it----leaking on the clutch and gluing it all together, I think you have air in the clutch hydraulics.

Look up under the dash by your left foot. Do you have any fluid leaking from the master clutch cylinder?

Here is a reverse bleed solution. To properly work, disconnect the clutch master cylinder shaft to clutch petal---simple clip holds it on.

This is a real common problem on old trucks that have sat a long time. There are enough metal fibers in the clutch disc material that they can rust to the flywheel. Soaking the disc with water will frequently work, but isn't awfully good for the rest of the clutch, and it would be hard to get the water into a 944 clutch. Most of the other tricks that work would be pretty harsh on a rubber center disc; the suggestion above (#3) might be all it takes to shear one of those.
