Tapping Noise
I changed oil in my truck probably about 2 weeks ago.I put in some 15W 40 Rotella. Changed the crankcase breather, air and fuel as well. It sat for about a week after that now I'm getting a slight tapping noise from the engine. Could it just be the oil pump or could it be something worse. 77 F-150 400 C6 2wd

All the time from what I can tell, my exhaust is to loud to see if it does it during acceleration. I thought I heard it last time I drove it, but after it warmed up good it seemed to have stopped.

What oil were you running before? rotella 15w-40 or some other weight/brand? like fmc said you really need a mechanical gauge to know what actually is going on, the factory gauge is just a guess at best.

Before the Rotella it was running Trop Artic 15W-40. I don't know how quick I'll be able to get a mechanical gauge on there but I'll do my best. Can I use the existing sending unit?

A mechanical gauge uses a 1/8" adaptor to run a nylon or braided hose from the oil filter adaptor to the gauge.
At the same time you could install a T-fitting so you can have the mechanical gauge and factory gauge at the same time.
What brand oil filter are running?

Lifter tap, correct? It's normal them for them to tap slightly for a few seconds at startup. But anything more, I'd be concerned.
I get all kinds of startup noises whenever there is a Fram filter on. I even refuse to put a Fram on the crappiest vehicle I own. I use the Motorcraft FL-1A. They are only a dollar more than the Fram, and it's a much better filter.

Fram filters, which for how popular they are, are just pressed cardboard endcaps and crappy filtering media.
Basically the filter instantly goes into bypass mode.
Also, the tapping at start-up is due to the fact fram cannot keep the oil from draining back into the pan.

Just some food for thought

I generally use the NAPA gold filters, their a pretty decent filter for the money.
