I'm looking on Amayama for a gasket kit and the overhaul vs grind kit is less expensive. Doesn't make sense - apparently they're both Toyota. From what I know Amayama is all genuine parts, right? Based on other parts, they might be Daihatsu parts (still Toyota, but "cheaper") - but it's not stated there. Rebuild videos often have Felt Pro - are those better than OEM? What is the "SUBS" package supposed to offer? It looks the same as the first one. I read that some take the head to a machine shop for a valve job and to get the head's mating surface checked. Is this really necessary? In other videos, I saw the mechanic scrape the old gasket sealer with an olfa blade, sand with a very high grit to make sure the surface is clean and that's it. I'm at 237k km (147k mi). I want to do a proactive overhaul/cleaning just to make sure everything is in good shape; 2012 3rd gen. Trying to extend this car's life a few more years. So, water a pump change, spark plugs, egr cleaning etc going down Nuts N Bolt's list all is in order. I suppose that should take care of it, right?
