Leaks, overheating, rough running
Valve cover gaskets and rear main seals are common sources of oil leaks. A failing radiator shows up as overheating or coolant on the ground. Worn spark plugs make an engine idle rough and burn more gas. All of these are on the list.
Up to a full replacement
When an engine is past saving, Leo does engine replacement too. Call and talk it through before you decide.
