2011 Prius Two - I need advice And opinions on Mechanic quote

This forum has been awesome. Reading through all the posts and watching videos referenced has taught me so much about my 2011 Prius Two. It is a recent purchase and I thought I was familiar enough to inspect the car before purchasing. To my defense the deal was good and when things are sound too good to be sometimes it is... My last purchase was too good to be true and has been excellent and the one before that.... with that said, I don't need to be told I should have had it inspected by a mechanic before I bought it, please. I've never had an issue with getting it wrong before and this is the 8th vehicle I've bought over the past 23 years. I research and maintain my vehicles and never had a "lemon" but honestly I think "lemons" get created later in the life of the car from poor maintenance. And some years are just bad in some models straight out of the factory. But that aside

I have an engine knock. Found a very highly recommended Prius private mechanic and I'm having a misfire that is creating my knock. BTW, he found the oil over filled and explained how that can spit that excess oil at the spark plug... if I'm not wording it exactly correct please forgive me. He recommended that the EGR & intake be cleaned, tune it up and replace the sparks plugs, replace both air filters, then an oil change. I believe watching all the videos and reading all the DIY instructions that I could to the work and install an oil can while everything is apart.... but I really don't have the spare time and don't want to be without a car for an extended period of time.

And my question is do ya'll think $850 is a reasonable price?

Now issue two, the mechanic didn't pressure or push this but gave me this information as the next priority for service I need to do and through the forums I haven't read anything much about brake problems, specialty rotors. Someone just put on new brake pads but didn't turn the scratched up rotors. Also they just replaced the brake actuator and pump. He suggested I replace the rotors with a specialty rotor that he loves. I didn't get the name but he showed them to me and I'd describe them as rotors drilled with holes and a few grooves. He quoted new specialty rotors with a flush for $450. This seems high to me.

So all frank and kind opinions very welcomed and TIA

 

Thank you all!

Maybe I shouldn't say knocking.

I think it's loud but recreating it for other mechanics to get second opinions. It's more like a misfire vibration when the combustion engine comes on. To me, too loud and not okay to ignore.

 

BTW everyone I actually think my Hubby and I with the help from this site and the amazing videos posted by @NutzAboutBolts are going to DIY and do the cleaning and maintenance and install an OCC

My list so far is clean PCV, EGR, Intake manifold and throttle body. Change spark plugs and coils, oil change, cabin and engine air filters, engine and inverter coolant and install the OCC.

We have the luxury of having the car apart and protected and we figure while we have it apart to do everything we can think of that might be past due or about due.

Please add anything to my list I have missed. Thanks ya'll!!!

 

Thank you
