Thanks for the advice I'll switch the gauge to the other side to see if it makes any difference, Guess I could ck my 55 to see which side it hooks to. I have considered bypassing the filter to see if that helps. I may be wrong in my assumption on which is the in side of the filter and which is the out flow. I am thinking the oil flows in the bottom , thru the filter, and out the top on the side. or is it the other way around. Been trying to find a sort of diagram that would show how the oil is suppose to flow thru the engine so as to try to figure out if I may have a blockage somewhere. Thanks again for the come back
