Want this question answered?
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
sounds like your engine needs a valve job worn piston rings would also cause low compression ,but not cause the backfireing
A "Bad cylinder" or "dead cylinder" is a cylinder with Low compression psi. Symptoms: rough running low power can cause high oil consumption
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.
If it is causing the cylinder to misfire, yes.
how to fix a cylinder #1 has low compression diagnose on 2.9 chvy colorado 2007
You have to take out the cylinder, how low is it, what is the difference
Loss of Power
A bad lifter, worn piston rings/cylinder walls, carbon build up, bent push rod, and a worn cam lobe. A burned valve can also cause low compression.
Low compression on that cylinder. Oil reaching that plug, or a defective injector on that cylinder. Also a blown head gasket can be a cause.
It should be a high of 185 and a low of 140
maybe you need a new head gasket?
