Engine Oil Leaks

NOTE: When diagnosing engine oil leaks, the source and location of the leak must be positively identified prior to repair.

Prior to carrying out this procedure, clean the cylinder block, cylinder heads, valve covers, oil pan and flywheel with a suitable solvent such as Engine Degreaser (F4AZ-19A536-A) to remove all traces of oil. Make sure the oil in the crankcase is of the correct viscosity and the correct level.
