Engine Oil Leaks
NOTE:
If an overnight drive is done, the fan air or road air blast can cause erroneous readings.
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/flexplate with a suitable solvent to remove all traces of oil.
