When I bought the car it had no oil leaks. I changed the oil like I have countless times on other vehicles and now I have an oil leak right around where the filter's gasket seats up to the engine. Only leaks when the engine is running. Tried other filters, tried over tightening the filter...no luck. Any ideas?
Oil Leak on 1995 Honda Civic
On all three engine types that year there is an oil cooler between the oil filter and the engine block. Take off the filter ensure the bolt that secures the oil cooler to the engine block is tight (probably about 30mm), perhaps change the oil seals at the cooler.
