engine sound load

Thanks for the video, yes, it is a little loud, does the engine only have 80,000 miles? I would try changing the oil to the next heavier weight. Here is a guide to help walk you through it with instructions and diagrams below (generic):

Here is the stock oil:

Motorcraft® SAE 15W-40 Super Duty Diesel Motor Oil (US);
Motorcraft® SAE 15W-40 Super Duty Motor Oil (Canada)
XO-15W40-QSD (US); CXO-15W40-LSD12 (Canada)
WSS-M2C171-E 14.1L (15 qt) with filter

Oil Filter - 3C3Z6731AA

Please let us know what happens.

Thanks, Ken you are right, i forget to say it is a used engine i have installed due to the original engine having white smoke and injection no 8 is not working and number one is 50% work. i will post video for the old engine.
The millage is what appears in the dashboard every 2,000km i changed oil and filter the same you suggested. This is the third time i changed oil and filter. To be honest the loudness decreased a little bit from the first time i ran the installed engine.
The car accelerates very well, no engine shaking, rmb study no heat no smoke comes out just my concern is loudness i wish i can bring it down.
I will post pic oil gauge how it locks and after i wipe it i changed oil two days ago i drove it about 30km.
Thanks again Ken for your time and for trying to help.

The oil looks okay, the white smoke means the injectors are bad or the engine is worn out and the compression is too low not burning the fuel completely. You say the noise level is better with the new oil? It might be all you can do; some engines are noisier than others.

Thanks Ken, do you think it is lifter or roller could cause this sound or i should save my money and accept the fact some engine is louder than others?
Thanks again Ken for your time your advice very important to me.

I don't think it is a lifter, I would run it and just know this engine is louder. Please use 2CarPros anytime.
