2001 s40 timing and compression

My question is if the timing is off, will it make a difference in the compression readings on the individual cylinders?

Depends on how much "off" -- if just enough to bend the valves on some, then the answer is 'Yes'

Again Regent thank you for your comments basically what am trying to do is to fine out if I should spend any more money on this car. Volvo wants $45.00 for a new timing cover . The cars in good shape the timing belt looks as it has been replaced before the car has about 148,000 miles on it . As I said in my other post the car runs as long as you have your foot on the gas pedal and runs quite well but will not idle. Personally I think it's the timing. I'm a shade tree Mechanic that likes to work on old American cars. This cars my daughter's again think you for all the input

Poor idling may be due to a vacuum leak or ICM. I do not know of any timing reference marks other than those on the cover; maybe someone will chime in with a workaround?
