Thanks for the fast replies, guys.........
The chain was replaced less than 1k miles ago. I would not know what the compression is without taking the car to a mech. I suspect that it has been quite some time since the valves were checked last, however, this should have been completed when the chain was replaced?. Current oil is fresh Castrol 10/30. North GA climate this time of year is upper 50's for highs and lower 30's for lows, typically.
