Well, I am not sure what to do next, a rebuild head is $275. Its hard to believe that toyota used solid lifters and not hydraulic on this engine. There is no lash adjustment, shims are used in the tappets to set the clearance. Another thing is the engine has reverse cooling, the coolant goes in through he head and out through the block, which is great, but looks like they modified an earlier normal flow design by adding something to the head. The thing that gets me is the outlet goes to the bottom of the radiator and the inlet the the top, so all the air gets pushed into the head. Crazy Japanese engineers, Bosu, kakka, sensei, enjin ga ōbāhītodesu! " Boss, your excellency, sir, the engine is over heating"... " Use a bigger radiator and add an oil cooler". Of course someone one unwittingly could have switched the hoses around when they changed them, but the whole engine compartment is a rats nest of stuff added on.

I guess I should get a manual for it to get the specs for assembly..
