you either have bad piston rings or your valves are staying open. Other Possibilities: Blown head gasket; cracked cylinder head; cracked piston.

Can you give sentences with the word compression?
If your car seems to be losing power, you should check the compression of the engine.A patient who has received severe burns may require a compression bandage while he heals.Osteoporosis may cause compression fractures as the bones weaken and become more fragile.The forces of tension and compression work together to make bridges strong enough to hold considerable weight.
How are transverse waves and compression waves similar?
they both make motion wave
What is the definition of compression?
Compression - Forces used to push objects together.
Why do you hear a sound when you clap your hands together?
the hands make a compression wave that travels through the air. Your ears pick up that compression wave and turns it into a neuron impulse that your brain registers as sound.
How can you make compression wave using a slinky?
when you pull one end of the slinky, the slinky travels through in waves.
What would make your car have no compression on your 89 Chevy Cavalier 2.8L?
May have snapped/jumped the timing chain.
What will make a big power difference on a 454?
If your 454 have low compression piston, you can replace it with high compression but you will need to use premium (91 octane) gas, but it will make noticable power difference
Why is it necessary to stagger piston rings?
To prevent oil getting by the oil ring and compression past the others. Also, if they were in line, it would tend to make a groove in the cylinder wall.
Other than hp what is the difference between a Chevy 307 and a Chevy 327 engine?
Both engines use the same crankshaft and rods, but the piston on a 307 is the same diameter as a 283 (3.875"), and the piston on a 327 is the same diameter as a 350 (4.000"). In theory, the 307 would be very torquey for it's size, whereas the 327 would tend to make good power in the upper rpm range. In actual practice, 307's were a low compression motor that produced reliable horsepower and good economy. The 327's had 10.5-1 compression and bigger valves to produce more horsepower and torque than had previously been produced in a small block chevy. High performance versions of the 327 were available in up to 375 horsepower with higher compression, solid lifter cam and bigger heads.
Why doesn't my RC car restart when engine is hot?
What is probably happening is the chamber that surrounds your piston has expanded and you do not have the compression needed to start your engine. Make sure that you roll your piston to BDC (bottom dead center) everytime your vehicle stops. This will prevent your piston sleeve from widening towards the upper portion which in turns cause your engine to loose compression. You may be able to start your engine if you roll your piston to the bottom of the sleeve by turning your flywheel. I would also be a good idea to make a mark (preferably a scratch) on your flywheel to indicate where BDC is.
How do you set time on a 1983 Chevy 305?
Bring number one cylinder to top dead center. Make Sher you on the compression stroke. If not your 360 degrees off with you piston setting for tdc. Make Sher that the distributor rotor is pointing at number one wire on the cap. That should put you in time.
What does it mean if you do a compression check and there is no compression?
It just means that the railway is not compressed. Say that the railway was compressed, then you'd make a compression check and the answer would be positive, but if it isn't it means it's not compressed. When something is compressed, it means that the temperature was too cold for the railway so it compressed. Hope it helped! :P WHAT???? this person is lost. Ok, when you do a compression test and you receive no compression, make sure your test gage is a working gage. with no compression this indicates that exhaust / intake valves are in the open position which stops the cylinder from sealing for compression, possible bent or broken valve,valve spring,or lobe on cam may be worn. Now if you have a low compression reading on a cylinder i recommend you spray WD 40 into cylinder sparingly and test again,called a (wet test ) if compression raises you have bad piston rings, if it stays the same, its a valve issue, possible piston failure
How do you compress the caliper pistons on a 2003 Chevy Suburban?
with a C clam , make sure the you use sameting to protec the piston
How do you push pistons back in on a 2006 Chevy uplander?
get a ring compressor put around the piston so it compresses the rings, make sure to drench the piston in oil and get a nylon mallet and carefully tap the piston into the cylinder from the top of the block but make sure you have the piston facing in the right direction and the caps go with the right rod and so on. hope this helps, tell me how it goes!
Can low compression in car engine valve get restored in driving condition?
Only if you drive to a mechanic. :) Low compression is caused by wear, either in the piston rings or valves. Driving will not cause less wear to happen, so it will not make wear go away.
What does 8 to 1 pop up pistons mean?
8:1 refers to the compression ration. I.e When a piston is at the bottom of it's stroke the space between the top of the piston to the top of the cylinder would be 800cc's the 1 refers to the space inside the head where the valves sit at 100cc's. Pop up pistons would be a custom machined piston that has a protruding dome in the center of it. This domed spot allows for the piston to compress the air fuel mixture into a tighter more confined space which when ignited will drive the piston down harder and faster making the engine spin faster which means more power to the wheels. 8:1 I believe would be around 103 psi. The higher the compression ration the more power the engine will make. i.e 14:1 would be 1400cc's to 100cc's Wanna learn more? Look it up on the web. There is endless amounts of imformation swirling around on the world wide web. ;)
How do you replace a piston on a small engine?
need to be more specific on what kind of small engine to give you exact information on how to pull the piston. . . but generally you just need to pull the head and cylinder off. . . the remove the wrist pin that holds the piston to the piston rod and your piston will come out. . . now getting the new one back is is going to be a different story :) . . . you are going to have to stagger the ring gaps to make sure you are holding compression . . . basically just make sure none of the ring gaps on your piston rings line up when you put the new piston back in and oil your cylinder pretty good too helps with putting it in and with breaking in the new piston.
