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.

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.

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.

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.
