The oil pump does not set the pressure clearance in the main bearings does. I'd start by cutting open the filter and looking for sparklies.

If the water pump was leaking obvious replace it, but why replace the oil pump?

Oil pump pickup tube loose?
Time to drop the pan, and have a look around.
Lots of miles on it?
Ever "rebuilt"?

I replaced it thinking it was the problem but was wrong

A loose pickup tube would probably suck air and never prime again. Unfortunately, you probably have a bearing issue.

Always some info left out...
Now, you can follow up on the suggestions. Post back what you find.
If your "mechanic" is avoiding you, you may as well kiss that $ goodbye....He's aware of what he messed up.
Maybe post where you are located, and someone nearby can help.

Watch out for that word "rebuilt". It will get you in a bind. Whenever someone attempts to sell you a "rebuilt" you need to demand the specifications. If they don't have them then that's all they did was "rebuild" it. A good friend brought me a piston yesterday out of a block that had 4 different bore sizes. One about .025" over!. The Pistons were 3.800 stock pistons! That engine was "rebuilt". Not rebuilt is better than rebuilt unless specs are furnished. Guaranteed doesn't mean shit either. Just guarantees that you will get another pile of crap when you bring back the one that doesn't work. Junkyard shopping and buying rebuilt will burn you almost every time. Buyer beware!
