I have a 94 ZR 440 and I changed the hoses on my oil pump and I removed the bolt to bleed the line from the tank to the pump. After that I started the engine and lifted up on the oil pump arm to bleed the lines from the oil pump to the cylinders. One line cleared the bubbles out fine but the other line will not remove the bubbles and does not seem to have hardly any oil in it. Does that sound like it could be a check valve problem or do you think it is a oil pump problem? Can you check the check valves? Thanks.

mabey try to bleed it out again. Mix some oil in your gas and do the same thing you did again. Im sure you can check the check valves but i think you would need one of those little vacume pumps(i think they are called mighty vac or minni vac). It is a little hand held pump thing that you can use to put pressure against the check valves and get them to pop with a certain amount of pressure. I would try to bleed it again first. Hope that helps.
