This all depends on why it has low compression. If the rings are worn out, the motor should be rebuilt. If one of the valves is bad, re grinding it or replacing them is the fix. Perform a cylinder leakage test to confirm it. You will probably need to take it to a shop for this, but unfortunately, there usually are no quick fixes for low compression.

What causes an engine to lose compression?
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.
93 Ranger 23L has poor acceleration and little power after having timing belt replaced could the pushrods have been bent when the belt snapped?
Run a compression test. If only one cylinder has low compression, it's probably a damaged valve or pushrod. If the compression is low in all cylinders the cam is probably not timed correctly.
What are effects of the engine compression being to low in a car?
Primarily the result will be incomplete burn of the mixture or no ignition at all. Reduced compression reduces the particle pressure of the molecules in the cylinder resulting in variations of the burn pattern. This results in uneven pressure build up in the cylinder which manifests itself in a lack of power. Thus drivability of the vehicle is affected.
Does low compression and engine won't start mean a blown head gasket on a car that overheated?
If it was a head gasket then the compresion would be low in the affected cylinders low compresion as a result of wear wil make the car hard to start and overheating can also lead to electrical problems, Besides blowing a head gasket, overheating can also cause a cylinder head ro crack. Low compression and engine not starting or hard to start are symptoms. As mentioned above, do not discard the possibility of electrical problems due to overheating. However, the prime suspects are blown head gasket and/or cracked cylinder head.
What could cause low compression in all cylinders of a 1986 Isuzu Trooper with an inline 4?
AGE ! if it is low compression and not no compression then your piston rings and valves are worn too much and the engine probably needs to be rebuilt.
Fix low compression in outboard motor cylinder?
You have to take out the cylinder, how low is it, what is the difference
How can you repair low compression in cylinder?
how to fix a cylinder #1 has low compression diagnose on 2.9 chvy colorado 2007
What would happen if don't fix my car from low compression?
Most engines lose compression over time, but each cylinder should have roughly equal compression. Even if compression numbers are not equal, however, it's usually not worth the expense to fix this.
What can cause low compression on one cylinder only?
Most of the times when you have low compression on one cylinder it's an indication that the head gasket is blown. If more than one cylinder has low compression and is hard to start the you most deffinatly have a blown head gasket
What are the symptoms of low cylinder compression?
Loss of Power
How do you fix an engine with low compression in all 6 cylinders?
The repair depends on what is causing the low compression. Low compression can be caused by a blown head gasket, cracked cylinder head, burnt or damaged valves, worn or cracked piston rings, scored block cylinders. It's kind of hard to imagine that an engine would have low compression on all 6 cylinders unless something major is wrong, or the compression gauge is not measuring properly.
What should the cylinder compression compression test be on a 94 3000gt be?
It should be a high of 185 and a low of 140
What are the symptoms of a bad cylinder in a car?
A "Bad cylinder" or "dead cylinder" is a cylinder with Low compression psi. Symptoms: rough running low power can cause high oil consumption
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 are the symptoms of a bent valve?
A popping sound (when running if it will run), backfiring, and low compression on one cylinder when testing with a compression guage.
Can low compression cause an check engine light to come on?
If it is causing the cylinder to misfire, yes.
Low compression in number one cylinder in a 1.8 dual overhead cam interference engine?
Low compression in one cylinder can mean several things. The valves or piston rings may need to be replaced. There may be a crack on the engine, or the head gasket may have blown. The engine should be diagnosed properly to see what exactly is the cause of the low compression.
