Oil Consumption Letter - Engine overhaul COMPLETED

Hello, all.

So my 2010 MDX Adv with 150k just got an engine overhaul completed at the dealer. After receiving the oil consumption letter from Acura, I contacted my dealer and went to get an oil change which I had to pay for (I've read various conflicting posts on other forums in regards to WHO pays for the oil consumption test. Also, I just had my oil changed maybe 200 miles before I received the Acura letter, so my maintenance minder was still reading 100%. Paying for an oil change is not an issue if there's a possibility of an engine rebuild). I brought the MDX back after 1k miles and resulted in loss of 1.3 quarts. I initially had a dilemma as the MDX drove great and only issue I had with the drive train was the oil consumption which progressively got worse--dilemma being Acura Factory built engine which lasted me this far versus dealer technician rebuilt engine. In the end, I decided to go with the rebuild. There was a 2 week wait for the parts to come in. They kept my MDX for another 2 weeks for the fix--and I had a brand new TLX for a loaner. While they had the engine open, I also had my timing belt and water pump replaced (which includes coolant change and all the accessory belts) And yes, I did the regular 105k service at the dealer few years ago so I did prematurely change the timing belt and water pump from the recommended service interval; but I wasn't too comfortable about reusing the timing belt when the svc advisor informed me they will be removing and reusing the existing belt.

It's too early to give a final verdict on the engine rebuild, as I've only put about 200 miles on it, but it's been driving great so far--can definitely feel the difference during acceleration. I'll update as I'll keep an eye on the engine oil level.

Thanks for the input! Currently at the dealership doing my oil consumption test and waiting to see what Acura will say.

Please keep us posted on the overhaul.

I was going to do the same timing & pump on mine as well. What did they charge you for it, since the labor was mostly already covered?

@Carpayment4life - Rallye Acura

@DBConz - $800 for Timing Belt+Water Pump KIT (includes accessories belt, coolant, power steering, etc.).

I've put about 1,500 miles on the MDX since the engine overhaul. The engine feels awesome--pulls like a brand new vehicle. I do hear a faint squeak from engine compartment whenever I turn the climate control on which wasn't there before the engine overhaul so I am keeping an eye on that but other than that minute noise, I am very happy with the rebuild. My first post rebuild oil change was done at 1,200 miles.
