Hello, I have a 94 pickup 4x4 5spd 22re, that I just replaced the clutch with the marlin 1200# kit. The previous clutch had 123,000 miles on it and was starting to slip, and would also roll backwards when parked on a very slight hill. So I got the clutch in and everything buttoned up. Have about 20 miles so far on the clutch. So today when I went to the bank I parked where there was a very slight incline and it was starting to roll backwards when in gear. It kind of like chugs with the compression of the motor it seems.

When I got home I pulled all the plugs and did a compression check. All cylinders are around 165 + or - 5lbs. So know what ? Leak down test? Valve problem? And also when I put it back together it now has a miss. When it rains it pours.

Any help would be great! Thanks Brad

I always use the parking brake, even on level ground. I have noticed that when parked on an incline that the truck will roll and if I put the transmission in the gear that matches the direction of roll, it wont roll. In other words if rolling backwards try reverse and see if it still rolls. Otherwise you are turning the engine backwards.

I will have to try that, and the miss went away with some new plugs and reassurance that I pushed all the wires back on.

How about adjusting the parking brake?

It is called a Parking Brake for a reason.

Why are you not using it as it also keeps the rear brakes adjusted

165 psi of compression x 4 plus the other sources of resistance is not enough to hold a vehicle the weight of a 4x4 pick up

I quit using the parking brake because it was sticky, but I guess I better just get under there and get it going again. Thanks

What gear are you putting it in when you park? You need to shift into either 1st or reverse. If you're leaving it in3rd or 4th or 5th the engine compression won't hold it on much of a grade. In 1st it should stay put unless the hill is pretty steep.

But, like others have said, pull the parking brake as well. Extra insurance plus as stated it keeps your rear brakes adjusted.

Also, a compression test measures dynamic compression at 100-200 rpm. Holding on a hill requires static compression - if the valves or rings are only very slightly leaky the engine will still turn over slowly as the air bleeds out of the cylinders. You can demonstrate this by putting a wrench on your crankshaft bolt and notice how easy it is to turn the engine slowly. It only takes 30-40 ft-lbs of torque to move the crank slowly, but cranking the engine at starter speeds takes closer to 200 ft-lbs.

I have a 93 4x4 ex cab V6 that I bought brand new. Only have put one set of breaks and factory recall head gasket and a power steering pump on in all these years. Clutch is starting to slip so I'm going to fix it up all brand new since I can''t bring myself to sell her LOL. Is there a better clutch than another or one I should stay away from?
