My omega 2.2 has only done 55,00 miles but has lost compresion on number 1 and 4 cylinders over a relatively short time .The oil is clean but I dont know what grade oil was used .There are no leaks ,no water in oil.Spark plugs changed but still low compression and only fires on two cylinders.Any ideas why?
1&4,thats a coincidence.i'd probably try removing the hydralic lifters an squeezing the oil out of them in a bench vice.changing the oil and recheckin the comps.possible for lifters to "jack up" with oil or contaminants.so a no cost test.(bar oil).
