me and my friend has been working on his 1989 Dodge Omni with a 4Cyl 2.2L Motor one day he was stoped at a red light and the car just stoped runing we found out it was the timeing belt so we replace it and timed it right now #2 and #3 Cyl had no compression but #1 and #4 have good compression
why?? the motor only has 118,000 miles on it
please help
thanks

When timing belts go the valves get smashed or at least bent and don't work until replaced. Never let a timing belt get too old ie past 60000 miles.

You have bent the valves in those 2 cylinders. When the cam stopped spinning, the pistons were still going up and down. Normally, the valves close in time to avoid being impacted by the piston, but in your case they were hit. You need new valves and new valve seats - and hope you haven't punched a hole in the pistons. For a car of that age, it's probably better (and definitely cheaper!) to just buy a second hand head and bolt it on. And next time, don't wait for the belt to break - change it when it's due.
Good luck!

It could be a couple of things none of them easy fixes. When you break a timing belt your valves can't come back up at the right time and it could be a bent valve or the valve may have knocked a hole in the piston or even a broken cam. Remove the valve cover and see if the valves are all coming to the top, You may have to pull the head and look.
Good Luck, UJ

Not sure if this will help but what I would do is re-check the gear position and make sure that the timing marks were lined up when you replaced the timing belt. One tooth off or wrong position means trouble. If you don't have one already, get an owners manual from the parts store, they really provide alot of information

When the timing belt broke, you probably either bent the valves in those 2 cylinders, so they are not seating (sealing off the combustion chamber), or cracked/broke/holed the pistons (same results).

4 cylinders run notoriously tight tolerances in the valve to piston clearance. Chances are, you bent a couple valves when the belt broke.

Blown head gasket or bad valves or broken rings or cracked block

either two stuck valves or bad cylinder rings . more then likely stuck valves. check the valve tappet clearance and check again.if still no compression maybe bad head gasket. but more then likely valves.
