If yours does, than filling it with ten quarts is overfilling it and could result in the symptoms you describe. The excess oil is being churned by the crank and splashed into the pistons overwhelming the rings.
Could be the cause of your crankcase pressure. |
Thanks for the info. This is the first time I've changed the
oil so the symptoms were pre existing......compression test was done prior to adding the additional oil. Sounds like I need to get under the car verify the oil pan number then drain the oil and add in the capacity that Canton has listed and mark the dip stick. I'm sure people think I'm a goof for doing this but I've lived life by looking as the dip stick and making sure my oil was between the add and full line.....I've never knew the dipstick may not be accurate to start with. Should be an easy fix
