No compression could mean a blown head gasket, cracked head or cylinder.
how to fix a cylinder #1 has low compression diagnose on 2.9 chvy colorado 2007
sounds like your engine needs a valve job worn piston rings would also cause low compression ,but not cause the backfireing
To repair a Briggs & Stratton 4.5 hp engine with low compression, first, perform a compression test to confirm the issue. If compression is low, check for potential causes such as worn piston rings, a damaged cylinder, or a blown head gasket. You can remove the cylinder head to inspect these components, replacing any damaged parts. Reassemble the engine, ensuring all gaskets are properly sealed, and retest the compression to verify the repair.
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.
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.
its a misfire on cylinder number 1, check your spark plug, plug wire and/or coil on cylinder number 1
You don't repair compression rings you replace them.
The number 4 cylinder is typically at the back of the motor while the number 1 cylinder is located at the front. This is done to minimize confusion and streamline the repair process.
I'm not sure of the exact values; they should be in your Haynes repair manual. However, if you compression test all of the cylinders and find one that is lower you have a compression problem with that cylinder. It is also possible to have 2 that are lower, this would most likely indicate a warp in the head between those two cylinders. Other causes for compression loss are damaged or gunked up valves that do not close all the way or a crack in the head.
The P0303 OBD trouble code indicates a misfire detected in cylinder number three of the engine. This can be caused by issues such as faulty spark plugs, ignition coils, fuel injectors, or even engine compression problems. To repair it, start by inspecting and possibly replacing the spark plug and ignition coil for cylinder three, then check the fuel injector and ensure there are no vacuum leaks. If those components are functioning properly, further diagnostics may be needed to assess engine compression or other underlying issues.

Where's the leak? Wheel cylinder, repair or replace, rusted line, replace, master cylinder, repair or replace.
