As of late my engine makes loud ticking noises and at low speeds sounds more of thumper when cold. I took it at the dealer and they said everything is fine but I am worried I got 88k and when out of warranty would cost me an arm and a leg. Is this normal?

Another thing I noticed first was when I did a hard stop I heard a whine and did not pay attentions, now that while also can be heard when giving acceleration when rolling but no other time.

Any input on this?
