Oil pressure drop ford 226 h

(quoted from post at 08:07:42 07/01/16) 48fotd,Take the crankshaft to a good automotive machine shop and have them mic and check the journals to see if it is within specs.It has all ready been turned to .030 under size and they can tell you if .040 or .060 under size bearings are available for it and it can be machined again.Also check the camshaft bearings in the block for being worn,as oil pressure loss can also be from worn camshaft bearings.

(quoted from post at 20:26:53 07/01/16) Opinions will vary, but .030 is about the limit for turning a crank and expecting to get much life out of it. Anything more is pretty much reserved for rare engines, or something that sees little run time.

Crank journals are "case hardened". Which means the outer surface only is hard enough to maintain a bearing surface. Once the surface has been ground beyond .030, that hard surface is getting very thin.

If possible, your best bet is to find a crank that has not been turned, have it miked, polished if in tolerance, or turned to first under, which is .010.

(quoted from post at 10:51:02 07/02/16) The Ford cranks at that time were cast & not case hardened. It should run a long time at .040 if kept clean with good oil & changes.
