Tapping noise!

In the morning when starting my truck the engine valves tap due to the oil settling. It takes a few seconds before the noise stops. The recommended oil weight is 5W-20.

Does anyone else noticed this?

Let me know what you think.

My 6.8 had that problem so i switched to Delo 400 and the problem went away. The oil also doesn't look as burnt between changes.

Be careful when getting away from recommended oil for these modular engines.

The tapping? Is it a hollow "slapping" noise or is it a light tick?

Piston slap is common - I've had it intermittent for awhile now, but I have the V10, which is not that much different. My son has a 5.4 that slaps occasionally.

Ticking might be an injector.

The best thing to do is get an opinion, then another, by someone that can actually hear the noise…and knows something about these engines.

Also, be sure to use a good oil filter that has an anti-drainback valve. Motorcraft is hard to beat in this area.

I don't think you should be getting the valve tapping or piston slap. I have had plenty of vehicles including my 85 and 89 F250s that I still have, that have done that, but I don't think your 5.4 should be. The only difference between now and zero miles on mine is the exhaust sounds a little beefier because the muffler finally is breaking in. I use Mobil 1 0w20 and love it. I've said this before, but I'll repeat, I don't suggest swapping from non-synthetic to synthetic on a higher mileage engine. Too many problems....
