What is the compression on each cylinder on a 5.7 liter motor?

A new engine would have 150 LBS or more per cylinder.
A used engine that runs real good and that has plenty of power should have at least 140 LBS. per cylinder. If there is more then a 15 LB. difference in any cylinder then you will have a rough idle and maybe an engine miss at a idle. That means there is an internal engine problem.

What is the Cylinder compression in a 2.5 liter engine?
The compression can be different from one engine to the next depending on mileage and maintenance. What is important is that all cylinders are within 10/15 lbs of each other.
Auto Technician A says the total volume of all the cylinders in an engine is called the compression ratio?
The volume of an engine is called displacement and is typically measured in cubic inches or liters. An eight cylinder engine that could hold 1/2 liter of water (or air) in each cylinder would be a four liter engine. As the pistons move to the top of the cylinder in an exhaust stroke, they theoretically "displace" the 1/2 liter of air in each of the cylinders. The compression ratio is calculated during the compression stroke. If the piston occupies 90% of the enclosed cylinder space when it is at top dead center, the compression ratio is said to be 10 to 1, or 10:1. If the displacement of the cylinder was 10 cubic inches, it would have been compressed to 1 cubic inch.
Where is the camshaft position sensor on a 4.6L?
The camshaft position sensor on a 4.6 liter engine is positioned on the side of the motor on the front of the cylinder head. A 4.6 liter engine has a camshaft position sensor on each cylinder head.
What should the cylinder compression pressure be for 1991 Chevy s-10 2.5 liter engine?
It varies from one engine to the next but, what you want to see is that all the cylinders compression readings are within 10% of each other.
What should the cylinder compression be on a 1997 Nissan sentra series 3 with a 1.6 liter engine?
What's more important is that all the cylinders should be within 10% of each other.
How do you fix a cylinder 2 misfire on a ford 5.4 liter?
Depending on year of vehicle - some have a separate coil for each cylinder 2 may be bad?Check plugsCheck plug wiresDo a compression check to see if problem is internal
Why 1993 GM 3 8 liter is Getting what looks like oil In the coolant system overflow tank but no antifreeze In oil Flushed coolant system 3 times In the last 50000 miles Has 156000 miles on motor?
Check compression for each cylinder. Your head gasket could be blown or crack in the head.
How do you fix a miss fire on cylinder 5?
Each cylinder needs fuel, compression and spark. You are missing one of those.
Does 2003 6 liter Chevrolet have a distributor?
No it does not, It has a coil for each cylinder.
Rebuilt 4 cylinder 2.0 liter LE engine for a 1994 Pontiac sunbird has no compretion?
Was it just rebuilt or was it like 30,000 miles ago? Did you have a buddy rebuild it for you, a shop or bought it from some where? How much compression do you have? First make sure the cylinder head has been properly bolted down. Next remove the spark plugs take some 80 or 90 weight oil and put about a tablespoon in each cylinder. Then do another compression test if the compression comes up it is most likely the piston rings. If the compression stays down it is most likely the valves.
How many motor mounts are on a 93 Grand Am 4 cylinder and where are they?
The 1993 Pontiac Grand Am for cylinder engine has four motor mounts. There is a motor mount on each corner of the engine.
How would a person test the compression ratio on a 1969 6.6 liter engine?
If you have the serial number of the car that the engine originally came from, there is usually certain letters or codes which correspond to the motor. Also, if you do a little bit of research you might be able to translate any codes or stampings on the motor itself. This will only be helpful if the motor is still at the original specs and has not been modified or rebuilt with different components that could alter the compression ratio. If you are totally unsure of the history of the particular engine, you can't find any stampings, or if its had any work done to it that could alter the compression, then you almost certainly must dissemble and measure all of the cylinder volume divided by the compression volume at top dead center of the piston travel, this includes combustion chamber volume of the cylinder head. Therefore if one cylinder has a volume of 50 cubic inches and the compression volume is 5 cubic inches, the compression ratio is 10:1, unfortunately this can only be done by really disassembling the engine, so sorry. just to be sure you really don't mean a regular compression test. that can be done with a gauge screwed into the spark plug hole. This regular compression test is done to each cylinder and is most useful to determine if any cylinders have substantially lower compression than rest. This could indicate a problem with the head gasket, valve train or piston rings. The readout from a regular compression test, done at the spark plug hole, is in Psi and can not really be used to determine what the compression "ratio" is.
