Oil pressure light, Deville 472 -72

Recommended Posts

Found out in the Shop Manual that it can take up to 30 second for the light to go out.

That feels like very nervous half minute on a rebuild engine :-/

If the 472 has the oil pump shaft that is driven by the distributor... pull the distributor and use a socket and an extension to drive the oil pump shaft till the light goes off... and for a few seconds afterward.

That will put oil to all of the internal friction surfaces of the engine.
