2011 engine noise
I have a 2011 f150 4x4 5.0 with 140,000 miles and I started it up a couple nights ago and I heard this noise this was a cold start when I drive I don't here the noise in the cab https://m.youtube.com/watch?v=79l-iX...ature=youtu.be
I have done some research and people are saying its normal but doesn't sound normal to me. I took it to a dealership and they just said ford makes knocking sounds it's normal. I'm not sure what to do?

If you have a FRAM oil filter replace it with a Motorcraft and see if the issue persists.

cmbezln - Is it an issue with the bypass valve in the filter?
NOTE: Motorcraft (and several others) oil filters have a heat resistant silicone anti-drainback, pressure relief valve. Others include:
- BOSCH
- Mobil-1
- WIX
- PRO-TEC (made by WIX)
- NAPA Gold (made by WIX)
- CarQuest

Actually it's an issue with the anti-drainback and pressure relief valve - made of nitrile rubber (which is prone to harden with heat). It's a LONG standing issue (going back decades) with FRAM oil filters and dry starts. Several automakers have issued TSBs about it.
