Do you need a new engine if there is no compression in one cylinder?
Depends on why there is no compression.
What is the individual cylinder compression for a Chevy 283 engine?
When it was new it had 150 PSI. per cylinder
What is the compression for a 1989 Chevy TBI 5.7 in a truck?
That engine FRESH / NEW should have 150 LBS. compression per cylinder. If you have more then 20 LBS. difference in any cylinder then it is not in good shape and a good VALVE JOB is probley in the furture.
What cylinder should my distributor rotor be pointed at after I put new one on?
Just about to fire no 1 w/engine at TDC on compression stroke
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 would cause low compression in 2 cylinder and erratic idle in 2001 jeep grand Cherokee?
maybe you need a new head gasket?
Should you have low compression after a head gasket change?
No, quite the opposite- the idea of gaskets is to ensure that an engine gives HIGH compression. If your car has just had a cylinder head gasket change and you are STILL getting low compression, then this suggests that the problem lies with the cylinder head itself- it may be cracked. Unfortunately there's no effective repair for this, the only solution is to get a new cylinder head I'm afraid.
What if your 05 corsa has had new timing belt new cylinder and valves but still no compression in number one cylinder?
Check the Piston Ring.
What causes no compression to just one cylinder 5 Got a 98 Explorer that has fuel and spark but no start Tested compression by hand and 5 has NO compression Reasons why Repairable?
bad valve, bad rings or head gasket. need to do a leakdown test and see where the cylinder is leaking. do a copression test with adding a tablespoon of oil in the plug hole. if you get some compression, it's rings. have same problem with 5.0 in f150. mine bad rings on one cylinder. probable cause would have started with a bad injector leaking fuel and washing oil from the cylinder. then on restart that bore would not be lubed causing premature ring wear. at 150k, time for a new engine.
1997 Chevy Tahoe you took it to a mechanic and was told that the number 6 cylinder is getting no compression and that you need a new engine Can this problem be fixed?
It would largely depend on why #6 has no compression. It could be a minor repair or it could be a major repair. If it is a major repair and the engine has high mileage it would be wise to replace the engine only if the vehicle is worth saving.
Should you put a heavy duty starter on a new 1776cc VW engine?
Unless it was built with high compression and or a "big" cam causing high cylinder pressures a stocker should suffice .
What does compression ratio mean in car motors?
In an internal combustion engine, there are cylinders that have pistons in them. When the piston is down you have an open cylinder that has a specific size of volume that it will hold. When the piston moves back up to as high as it can, it compresses all that space into the new space and that is the compression ratio.
