Lol...I've owned DI engines since they first came out - no problems - not one! Double lol...your link is to 10+ year old Miatas.... Pretty sure 2008 Miatas have nothing to do with 2020 Miatas! The current generation of Skyactiv engines are very reliable. I beat the crap out of one for 60K miles and know the current owner who has 105K miles on it and it runs like new....flawless.....I mean I REALLY beat the crap out of that engine just for [censored] and giggles.

I can't imagine how you can clean it inside of the head with all deposits flowing inside of the engine. Here is a topic with a list of blown Miata engines of some forum users. Though, it says that the engines were just thrown away, not rebuilt. https:/
