OIL PAN HOLES
General Information:
Oil pan leaks will be detected by oil in the engine compartment, low oil level and a possible lowering of the oil pressure.
The powerpack must be removed to inspect the extent of damage and to make repairs.
Repairs are normally made by
welding the oil pan, but if welding equipment is not available, and the hole is small, a repair may still be made using this
procedure.
After this repair has been made, frequent inspections will be required. Small cracks or holes may develop in
the engine or transmission housing caused by vibration, overheating, or explosive shocks.
Cracks that allow oil to escape
must be repaired.
Large holes or cracks will require replacement of oil.
Frequent oil level checks must be performed,
after repair.
Depending on the extent and location of the damage, the powerpack may have to be removed.
