oil change on the NG8 engines can result in them locking up too in some cases, and god help them trying to get to the spark plugs on them. - half shit will be broken and then they will scratch their heads why the plug tube isnt straight and why the plug has a 12 point 14mm drive head.
and then finally wonder why their "pilugg sarviss" didnt work and then swap coils around will transfer the misfire to other cylinders as permanent codes, and then forgetting to check airtightness of crankcase will result in the forever check light of manifold to crankcase vacuum relation error.
LOL.
And if they snap a belt to due being soaked in oil/coolant - fateha on owner wallet and car - it will probably be toyotafied in a jiffy and sold as "lush genwin paint, untuch no shower"
