WILL IT STLL RUN ?OR IS IT DEAD ?
If any two adjacent cylinders have low compression it's probably caused by a blown head gasket.
The repair depends on what is causing the low compression. Low compression can be caused by a blown head gasket, cracked cylinder head, burnt or damaged valves, worn or cracked piston rings, scored block cylinders. It's kind of hard to imagine that an engine would have low compression on all 6 cylinders unless something major is wrong, or the compression gauge is not measuring properly.
low compression in one of your cylinders
You distributor cap and rotor should also be replaced. If still no spark. check the compression on the low cylinders to see if you have good compression.
It probably won't start and run and a compression test would show very low, if any compression in all cylinders.
timing belt
head gaskets??? warped heads? did you have them milled?
No compression on all cylinders, assuming pistons are moving and valves are intact - would imply bad valve timing, most likely timing chain... Several other issues can cause low compression in misc cylinders but no compression across the board without a catastrophic event such as major overheat or fuel washing cylinders, blown crank, etc - but "no compression" again, first check would be timing chain.
Check the compression of the cylinders you will have a low reading in the one with a bad valve
The short answer is "yes". How low is low? And is compression low, and equal between adjacent cylinders? If you squeeze the radiator hose while trying to start the engine, can you feel pulsations? If the answer is yes to either question, you may have a bad head gasket.
worn or broken compression rings engine needs a rebuild
AGE ! if it is low compression and not no compression then your piston rings and valves are worn too much and the engine probably needs to be rebuilt.
