How much psi loss is ok on a engine block? Five to 10 percent loss indicates an engine in great to good running order. An engine between 10 and 20 percent can still run OK, but it’ll be time to keep an eye (or ear) on things. Above 20 percent loss and it may be time for a teardown and rebuild.
How much pressure is in a engine block? Cylinder pressures in a typical engine can easily top 150 to 200 psi during the power stroke; the piston rings keep most of this pressure in the cylinder, but their seal against the cylinder wall isn’t airtight.
What is considered good engine compression? Healthy engines should have compression over 100 psi per cylinder, with no more than 10 percent variation between the highest and lowest readings. … TIP For a cylinder below 100 psi, pour 1 teaspoon of engine oil into the plug hole and retest. If the reading jumps, the piston rings are worn.
Is 160 compression good? An engine is essentially a self-powered air pump, so it needs good compression to run efficiently, cleanly and to start easily. As a rule, most engines should have 140 to 160 lbs. … Low compression in two adjacent cylinders typically means you have a bad head gasket.

Do diesel engines last long?
What makes diesel engines work so well and last so long? It’s normal for your car’s gasoline engine to run for around 200,000 miles before it needs a serious overhaul, or you need a new vehicle.
