Low Compression usually means that the cylinder rings are worn. You should also do a leak down of each cylinder. That will pinpoint which cylinder/s are bad.
Also,possible poor seating of valves or improper valve seat contact.

∙ 15y agoFriction, over time. To expand on this, a compression test of a cylinder of a 4 stroke engine (an engine with intake and exhaust values) may lose compression due to worn piston rings caused by friction (and/or) values that do not seat properly. When the piston comes up on the compression stroke both valves should be seated tightly in their respected valve 'seats' to maximize the compression. The loss of compression may be due any or all of these parts.

∙ 14y agoan engine looses compression thru broken piston rings, ahole in a piston, bad headgasket, loose spark plugs, timing wrong, bad valves,so pretty much u need a mechanic to look at it

What does it mean when engine overheats but the car does not lose compression?
it means that the car wasnt overheated enough to gt to that point
What causes no compression on 2.7 Liter Chrysler engine?
Broken cam or timing chain is the most likely cause.
What is loose compression?
Loss of compression is caused by bad internal engine wear or internal engine failure. Both mean the engine will need serious repair
Main advantages and disadvantages between compression ignition and spark ignition engines?
A spark ignition engine is a gasoline engine. A compression ignition is a diesel engine.basic difference between compression and spark ignition engine is ,compression ignition is a diesel engine. spark ignition is a gasoline engine.diesel engines compress the fuel to a point where the fuel explodes, thus giving ignitiongasoline does not compress to explosion, therefore it needs need a spark to ignite the fuelspark ign. is gasoline. comp. ign. is diesel.A compression ignition engine is typically a diesel. It compresses air so much that the heat from the compression is enough to cause the fuel to ignited once injected. A spark ignition engine is your average gasoline-burning car engine. It uses a spark plug to ignite the air/fuel mixture instead of relying on compretssion ignition.A compression ignition engine uses very high compression of the air to heat it self up and the fuel is injected into the cylinder which self ignites (a diesel engine is a compression ignition engine).A spark ignition engine uses a lower compression ratio and requires the use of a spark to ignite the fuel (a petrol engine is a spark ignition engine).Because the oils used for a diesel have a higher calorific value, they have a better fuel economy, They also do not need extra energy usage to keep the engine running, unlike the energy that is lost to power the spark plugs from the generator/alternator which is taken from the useful energy produced by the engine.
A vibrating object pushes the molecules together and causes an area of compression?
True.
What causes the engine to lose compression in all 4 cylinders on a 1992 Stanza XE sedan with only 162000 miles?
broken timing belt
What causes engine to lose power going uphill?
Gravity.
What causes a 1995 Ford Probe GT 6 cylinder engine to lose power while driving down the road?
Check your spark pugs...it could be that or worse case it could be a compression problem with one of your cylinders
Does a head gasket make an engine lose compression?
Verification on your question: Do head gaskets make cars lose pressure....hmmmmm, I think what your asking is.... Does a head gasket make an engine lose compression. - Correct?The simple answer is yes, it does, but it is by design. The amount the head gasket lowers the compression (or pressure) is built into the overall design of the engine. For instance, if you were to assemble the head to the block, without a gasket, you would raise the compression (pressure) slightly and potentially cause damage to the engine. This would most likely become apparent when you burn out a valve or burn a hole in the top of a piston.In general terms: - The greater the compression ratio, the bigger the explosion in the bore and the more heat that is produced.
What does it mean when engine overheats but the car does not lose compression?
it means that the car wasnt overheated enough to gt to that point
What will cause 4 cylinders in the same row of a v8 engine to lose compression?
Blown head gasket is one cause.
What causes no compression on 2.7 Liter Chrysler engine?
Broken cam or timing chain is the most likely cause.
Which engine has highest compression ratio?
the diesel engine. it takes one ignition to start, then it runs off of (autoignition) ignition from heat caused by high compression. compression ignition (autoignition) causes ignition to happen a little earlier than spark ignition engines (gas engines) which is less vulnerable to risk of engine knocking or wasted power when dealing with high compression. -maddmatt
What causes an engine to not start?
If the battery and starter is cranking the engine over, the engine needs fuel, compression and spark to run. More info would help us help you.
What is the compression psi on a 1990 engine?
Normal compression on a gasoline engine is about 125 psi.
What happens when you lose compression?
flatulance
When doing a compression test on a gas engine do you start the engine?
No, The compression test is done as the starter cranks the engine
