The 81 CB750 DOHC is at a shop, I told em I needed them to check the valves as I was hearing slight sounds. They had the bike for other reasons I wasn't equipped to fix myself...
Under the valve cover was a melted gasket, a lightly scorerd lobe, and NO OIL.
They ran it with the top off and no oil was coming up. To rule out the pump they went in with a scope and it was operational.
Obviously the thing to do is remove the top end and find out what's going on. Maybe it's the head gasket. Unfortunately they have the bike and I can't afford to pay for a rebuild that costs more than the bike. So we're trying to brainstorm possible reasons the head is dry and hopefully y'all can throw your hat in the ring.
Clogged oil passage is the only thing I can think of. Going to have them go through the filter and pan and see if anything is there, but I can't think of another way to check for a clog without the head removed.
Anyone here have any ideas?
Worst case senerio is I fill up the head manually and ride it to my garage, but they are going to insist I tow it...
Thanks
