Yes, I don't buy DI engines, why would I need additional problems and know how to fix them?
For me, it's not a big problem to take out an engine head, disassemble it, and clean valves and passages thoroughly.
It's difficult to clean deposits even when you have a valve in your hands. 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.

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.
