Default did compression test on my gsr today

cylinder 1- 210

cylinder 2- 165

cylinder- 205

cylinder 220

car has leaking head gasket, car bogs at low rpms, and oil smells like gas, would head gasket contribute to low compression on 1 cylinder or could it be the rings or could it be valves?

thanks in advance if anyone helps

Sounds like it's running too rich, and the overfueling washed out the rings causing the low compression and the gas in the oil.. maybe a bad injector on cyl 2?

water in oil and or coolant hoses under high pressure indicate hed gasket failure, low compression in one cyl is usually a burned/bent valve, take the spark plug out and check for fluids.

the spark plugs look fine not covered in oil and the electrodes looked decent

the last time i came across this was on a ford explorer, engine would shake like it had a miss but had fuel and spark to all cyl, head gaskets where brand new and diddnt show any other failures. compression was down to 120 on one cyl and the rest higher, after the valve cover was removed we found a bent pushrod. maybe remove your valve cover and check for any loose rockers or broken springs. either can cause a misfire and or low compression readout on the corresponding cyl.
