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.

What should you do when a compression test reveals that compression is below average and the reason for a motor not working?
Low compression will not cause an engine to not run. It may not run efficiently but it will run. Low compression on all cylinders is caused by wear, and can only be fixed by overhauling the engine. Low compression on just one cylinder can be a blown head gasket, burnt valve, or a broken ring on that cylinder. I also depends on what you mean by "below average". An engine with lots of miles may very well have a compression reading that is below the factory specifications and not be cause for alarm. It depends on how much below specs that compression is. In any case, the only fix is to open the engine up.
What is the cylinder compression on a 5.7L vortec?
The ratio is 9.5.1 in the 350 vortec. Doing a compression test you should not have any below 100 psi and all should be similar to each other.
What are the proper compression readings for a 1997 Dodge Neon?
The compression in each cylinder should be within 10% of the others. 125 to 140 is rather poor, below that it probably won't start.
1958 Cadillac what octane of gas?

My penis is 5.5 inches when erected. is that average or below average?
well if your under 16 then about average but older it should be about 6
How do you calculate compression ratio?
compression ratio = compressed size / uncompressed size the ratio should be between 1 and 0 (multiply with 100 to get the ratio in percent) a ratio greater than 1 means, the compressed size is actually greater than the uncompressed size a ratio just below 1 means bad compression the lower the ratio, the better the compression
What should the cylinder compression be on a 1995 polaris 300 4x4 ATV?
i believe anything over 115psi should be fine. 115psi is the service minimum, as in if it drops below that the engine needs a rebuild
What do you do if a compression test for a Mitsubishi Montero reveals below average compression?
Common Montero problem. It is time for new rings. Oil is seeping into your cylinders. You can drive the truck like this for a long time without really having a problem - just make sure you keep checking your engine oil level. If your state does emission checks, you're going to fail. If you get the rings done, you'd do well to complete an engine rebuild while you're at it; the motor's already wide open, so you're going to see significant savings on labor.
Compressional waves caused by colliding air molecules?
Yes indeed, Sound waves will have alternate compression and rarefaction pressures. The air pressure goes above and below the average air pressure.
Where is the compression stroke located on a 1997 dodge ram 2500?
The compression stroke is not part of the engine. It is what happens when the pistons are on the upward with closed valves.See link below.The compression stroke is not part of the engine. It is what happens when the pistons are on the upward with closed valves.See link below.
