Q: Heavy oil leak when car is on

asked by on

The oil leaks heavily when the engine is turned on.

A: The first thing to check is the oil filter....

The first thing to check is the oil filter. Was the oil changed recently? Remove the filter and check the gasket. Did it push out of the groove? Are there two gaskets? Some other sources of pressurized leaks are a broken oil sending unit, or a head gasket. A mechanic can inspect and repair the leak to get your car back safely on the road.
