Signs of a dying oil pump?

So I've had this problem for a while now but it is getting worse and has got me concerned. Whenever I start my car, I'm getting slight knocking sounds along with valvetrain noises and it just sounds terrible. It usually goes away almost immediately but it is getting worse. I talked to a friend about it and he mentioned that it could be taking too long to build up pressure because my oil pump dying, and only to add to the fire, I have to oil psi gauge haha......

My motor is healthy and still pulls hard after 157k on the clock and a full rebuild is out of the question at this moment.

Anybody have any ideas?

If a rebuild is out of the question add a bottle of Lucas oil stabilizer and turn up the radio.

If you're Mexican, I hear MDF dust works good.

If you're not, dump some Lucas in there, but remember it's not fixed and just hope it lives lol.
