Condition
Some owners may comment on a repeat engine oil pan leak.
Cause
The engine oil pan leak may be due to an uneven (rippled) sealing surface on the oil pan.
Correction
Seal the leak with RTV sealant using the following procedure:
1.
Remove the oil pan from the engine. Follow the oil pan removal instructions found in the Engine Mechanical section of the Service Manual.
2.
Remove the old RTV sealant from the engine block at the joint face sealing surfaces and the oil pan. Use only a plastic or metal scraper as
described in Corporate Service Bulletin # 00-06-01-012.
Important:
Ripples which appear in the oil pan sealing rail surfaces of the oil pan will not affect sealability when using this procedure. Do not replace the oil pan
for this condition.
3.
Inspect the oil pan sealing rail surface for bends or distortion which would affect sealability.
4.
Clean the engine block and oil pan mating surfaces using a solvent that leaves no residue, such as P/N 12346139 (in Canada, P/N 10953463), or
equivalent.
Important:
In the steps that follow, it is strongly recommended to use a 5 oz. (142 ml) RTV sealant cartridge and a hand-actuated caulking gun. This will help
assure that a continuous bead of RTV sealant will be applied to the gasket surfaces.
5.
Use a new oil pan gasket and windage tray assembly, P/N 24502397.
