PUT IN A NEW CYLINDER BLOCK NEED TO TIME IT NOW

Try bleeding the slave cylinder first.changing a clutch involvesmore than you can learn on this site. You need a repair manual. I recommend Haynes manual. You can find manuals at any store that will sell you a clutch.

Any chance the timing is actually 180 degrees off ?
The obvious answer is the valves are not closing at the right time. That is assuming the head gasket is torqued and you have no cylinder leaks in the block.

Carbon build up, burned valves and seats, piston ring wear, a general mechanic can tell you if the engine is having compression issues but you should have a cylinder leak test done to see where the problem is exactly.

Do you have a warning light on? If so get the trouble codes read.

This is the direct definition of this code
Mitsubishi DTC P1390 - Timing Belt Skipped 1 Tooth or More.
Probable Causes,
-Timing belt improperly installed
-Camshaft position sensor improperly installed
-Camshaft position sensor connector improperly connected
-Crankshaft position sensor connector improperly connected
-Camshaft's relative position not relearned after one of the following have been serviced: Camshaft, Camshaft sprocket, timing belt tension-er, cylinder head, head gasket, crankshaft sprocket, crankshaft cylinder block or the PCM.

Sounds like something to do with the timing belt it self. You can go to any Autozone or Checker and ask for a code reader (they will let you use it for free) and it will show this code again. You can also reset the cars computer with the code reader to see if it comes back with the same code.

did you reset the alarm/ immobiliser after the battery was re connected??

The starter in located on the drivers side engine compartment above the trannsmission. Just look for a cylinder shaped metal part....

check clutch fluid reservoir, fill-up. or replace rubber cup in the clutch master cylinder.
