Yes that and the excessively THICK 98 cold psi and 65 at idle doesn`t seem ideal to me personally. With fairly large bearing clearances in my motor I still run 5w30-10w30 oil and even though I have an 8-quart pan, I run bet 6-7 quarts and have about 70psi cold and 30-40 at idle/cruise.


Cool, you're entitled to your opinion, but tell me this, how many cases of rod bearing failure have you heard of, that was attributed to too high of oil pressure? I'm guessing that I'm allot older than you and I've NEVER heard of high oil pressure causing bearing failure. Granted it robs horsepower, but this is my choice to have higher pressure......... I've heard of many, many more failures due to too low of oil pressure, rather than too high.



I have heard of it "washing" the bearings, That was in an 8500rpm dirt latemodel engine. It would accually just force the oil out of the bearing, I dont understand it for sure either, but the engine im talking about ran 20w50 with .003 rods, and mains, and he had 95+ psi oilpressure, and had a bearing failure on his small block, when he changed the pump to no more than 65psi at the same rpm the bearing issue went away.

so from that I honestly dont know why...
