OK I do have low oil pressuure sound like a tractor. A little with a bottom. End tap. It increases with throttle. My oil pressure in 0 when warm. But it has just started burning oil Idk if its valve seals. To much sludge or Wat.
Its Kinda worrying. Me I'm praying. Not rings haven't had it over 220degrees in over a year when my waterpump went out the smoke is blue. no milky oil just changed in and its black.
I also seen sludge in spark plug holes Im praying it is pcv. Or valve. Seals. If u can understand. It. Help would be apriciated

Need to verify the oil pressure with a mechanical gauge before proceeding with anything else.

That motor is toast. 0 psi when warm. Pump failed you ran it too long. Yank that motor. Get a new one.
It will soon blow a hole out the side.
**** poor maintenance is the cause of this.
Not saying you never maintained it. The po prob never changed the oil.

If you have cleaned out the oil passage that feeds the pressure sender and have zero pressure with a mechanical gauge- not good news.
Combined with the smoking, noises and other problems, I'd agree it's probably rebuild or replacement time.
You might try a new oil pump, sometimes you get lucky, but given the other symptoms and the possibility it's been running with no measurable pressure for a while, it'd be a short-term fix I think.
