Last MG I had with 25psi at idle needed rod bearings...it still ran hard, didn't use any oil & there was nothing wrong with it...at speed oil pressure was 75 also....but, when I crawled up under it & removed the oil pan, the #3 bearing showed bronze......that's not a hard check to make! I'd rather do it early enough where all I have to do is redo the bearings rather than later when I have to turn the crank!
