1994 low compression

[rw1456]

My 1994 F250 7.3L turbo with 180,000 miles is in a diesel shop. They tell me 3 cylinders have low compression in the 250 lbs range, they also found bad injectors. They replaced the one injector that was bad and that cylinder is firing now and he says the engine is running better. He said since there is enough compression to fire that cylinder, he recommends changing the injectors. My question is this: Is it worth putting new injectors in a motor that is low on compression? Thanks.
