This is strange.... Changed oil & filter as always. Oil pressure sender reads expected pressure.... Next day, I open up the filter canister and it's not full like it should be, only maybe 1/3 full or less, after maybe an hours worth of total driving.... I've never had that before, not sure what to look for. Any suggestions>
Fuel sender ???? Ya mean oil don't you? Pull both line to filter and blow through. There is a .062 restriction fitting on one side or the other you may have gotten a bit of dirt in that orifice.
Mine has never remained full - maybe you just got all the crud out of the lines so it can drain down......
There is a drain hole on the center tube about a 1/3 of the way down. After sitting it drains down. I don't think mine has ever been full when I change it, always after at least an overnight sitting.
Like John says above, there's a restriction fitting where the oil enters the filter housing. It's possible a chunk of crud plugged up the little hole.
Ours always drains down. Nothing to be concerned about...it's a "bypass" filter anyway, not a "full flow" filter.
