So I'll break things down on what has happened.
-Engine-
As mentioned before. The short block was changed with no change to the noise the Evo was originally making. This was a huge punch to the gut. Moving on, it was determined the noise was coming from the head. So we went ahead and swapped out the BC camshafts for some stock Evo IX cams.
The noise was drastically reduced. But, it was still present. This was bothering me, as I could not figure out what it was. Even after taking it to a friend of mine who has assisted with some of the engine tear down had no idea what to make of it. We would basically need to pull the head apart to figure out the cause of the noise
Despite this noise, the engine was running very healthy, and a engine analysis was even sent into Blackstone Labs. They were happy to report no metal shavings or abnormalities were found in the test/sample.
So the next step was to have the head replaced. Unfortunately, the Mitsubishi dealership near me has closed permanently. Thus, I am not able to get at-cost pricing. The price for a brand new head at another dealer/online is way more then I am willing to pay.
So my next best option was to purchase a used low-mileage head from a reputable vendor I know. With the head purchased, it arrived ready for installation.
So things purchased:
- OEM used Cylinder Head
- OEM Headgasket
- Misc gaskets
There have been quite a few things that have happened between 2018 - 2019, but mostly in resulting of miss-diagnosis of what the actual issue was. So it's been a very expensive learning process.
