Service bulletin M012429800

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

The new 571-9902 Cylinder Head Gasket kit has funnel seals that divert oil from the cylinder head back into the oil drain passage in the block. This oil diversion prevents oil from collecting between the cylinder block and the spacer plate gasket (shim gasket).

The document
