That is a method of checking compression.best way to check is to do a cylinder leakdown test, do it dry on all cylinders, and then add a cap of oil to each cylinder and try again, record ur results, if the results change dramaticly after adding the cap of oil its cylinder rings and if the results dont change then its the headgasket or valve seals
Like about 5 miles till I found a 7 11!Uhhhh how long did you drive it with the oil light on? That is some severe oil deprivation that will cause that light to come on.
You may have damaged oil contol rings because of it.
that is a method of dong a leakdown test, i undertsnad u can also add oil during a compression check but adding oil during a leakdown test can also help pinpoint the area where the air is leakingThat is a method of checking compression.
For a leakdown test, you need see how much leakdown you have (how much air is escaping) and where its coming out of (listening to oil passages, out of the intake, out of the exhaust, bubbles in the radiator). If you hear whooshing through the oil passages, its the oil control rings.
