120 - 140
100-125 psi
100-125 psi
typical compression test reading fora diesel engine
150 psi should not vary by more than 10 psi between cylinders
If the difference between the high and low reading is within 10%, it is withing normal specification. If more than 10%, try squirting oil into the low cylinder and retest, if compression comes up , this indicates a bad ring, if not indicates problem is a bad valve.
Hi,iv'e got a 4hf1 Isuzu. What will the correct compression reading be if i do a test on the engin?
do it with engine warm for better sealing, pull all the plugs so it is easier on the starter and disable fuel for the test

A box compression tester is a machine that measures the size and quality of boxes. It uses a variety of techniques to test the strength, durability, and compression of boxes. The box compression tester can also be used to test the strength and compression of packaging materials. Most manufacturers use this type of machine to test the quality of the boxes they use to ship their products.
