My 08 fj is close to crossing the 200k mile mark🎉 and I'm thinking about doing an engine checkup on it in the summer. I'm wondering what parts I should look at and if anyone has any instructions on how to do any of the steps for the engine work that would be greatly appreciated. My guess is piston seals, clean the injectors.... anything else that commonly goes out at this mileage? I've done a lot of suspension work on it, but have yet to touch the engine. I plan to teach myself through experience as i did with the suspension. It's a 4x4 AT and is completely stock under the hood. Thanks!
