Just wondering, say if you had an engine that consumed oil past the rings, would this engine have low compression and blow by to go with it?
If an angine had no abnormal blow by levels and burnt no noticable oil could you presume it had good compression across all cylinders?
My old Mitsubishi 2.6 with 270k (head blew at 299k) burned a lot of oil and smoked like crazy with 20w50 plus Lucas in the sump! That engine also had pretty massive blow by, when you loosened the oil cap with the engine idling it would blow the cap off! If you revved it, putting your hand over the fill hole blew more than putting your hand over the exhaust haha
My Falcon with 210k on it uses virtually zero oil with just 10w30 and at idle no air can be felt coming out of the fill hole at all and only a small amount when revved which is normal in even new engines. Could I presume from this that the Falcon has full/good compression?
