Why would a motor loose compression in a 5th cylinder when it is a 6 cylinder?

from what i know there is no difference in what piston loses compression based on the layout. a piston loses compression due to faulty valves/seats/stems or damaged piston rings. if you have low compression problems, check the above, in that order

Compression on Chevy engine 5.7?
Depends alot on the year, and how many miles on the motor. Anywhere from 80lbs, and up. What you are really looking for, is a difference. One cylinder 25, or 30 lbs lower. This would indicate a dead cylinder.
What is normal cylinder pressure for a small block Chevy?
Anywhere from 80, up to 180, depending on ther compression ration, effective compression ratio, and how many miles on the motor. Lower than about 80, is getting low. Also, you are looking for a cylinder that is really low, compared to the rest. 30 lbs., or more, lower. This would indicate a dead cylinder.
What would cause f350 6.9 diesel to lose power and have white smoke come out of tailpipe?
blown head gasket,it causes the coolant and gas get mixed in cylinder,that cause the white smokeyou also loose compression which in return you loose power
Cylinder compression on a 1996 mercury 175 outboard motor?
It should be some were between 120 to 125 on all 6. That would be on a motor in good condition. 115 to 120 is not bad. Just make sure they are witnin 20percent of one another.
What would be wrong with a Chevy s10 after changing timing chain the timing is right on but runs rough no compression in cylinder 4?
The year and engine size would help but you may have a bent valve or bent pushrod for # 4 cylinder if that is the only cylinder that has 0 for compression.
What cylinder do you bring up to compression stroke and then where do you point the rotor bug to fire the motor on a 2001 Chevy 4.3 liter?
Number 1 cylinder, which would be the first cylinder on the drivers side of the engine. You want the rotor pointing towards the 5 O'Clock position looking at the distributor from the front.
What would happen if a cylinder broke in a car?
The cylinder would lose compression, causing the engine to lose power. I've personally never heard of a cylinder breaking, its usually parts near and around the cylinder that break, although if the block cracks, I guess that could be considered breaking the cylinder. The cylinder can also lose compression due to rust holes which can develop over time.
What would the compression raio be if a cylinder has a volume of 250cc and a combustion chamber volumeof20cc?
357cc
Why would an engine have poor compression?
The Cylinder head could be damaged or a ring out of place, causing the release of air, making less compression
What would the symptoms be for a compressor that has two cylinders and only one is pumping?
How do you fix no compression in one cylinder? Yes, a dead cylinder can be fixed by checking and rectifying any defective component that falls among some of the reasons that result in a dead cylinder; in order to fix a dead cylinder, you will have to diagnose the cylinder by using a compression gauge to test whether there are any cylinders with no compression. Usually, a leaking gasket.
What is the compression supposed to be for a Chevy 350?
When you run a compression test, you are really looking for a cylinder that is way out of line with the others. 40, or 50 lbs lower than the rest, would indicate trouble. As for a number, well there is a lot that contributes to the actual answer. On my race engines, I come in as high as 180, to 200lbs. A motor with 80,000 miles, and 8:1 compression, would be lucky to put up 100lbs.
Why would a 1993 acura integra turn but won't start?
