Gen4 3SGTE Engine Head Reconditioning

In this video, I attempt to clean and recondition the head of my Gen4 3SGTE engine that will go into the Mk1.5 MR2 build.
The many useful documents for these engines can be found here: gt4.mwp.id.au/

16:38..man, ur risking the flatness of the mating surface..it would b best if u use a straight edge,roll the sand paper n just go softly on it.

Yes the thought came to mind. I tried to minimize the risk by using 500 grit but there is always a risk. We will see when it goes in the car :)

Im curious, why did you take the engine that far and not replace piston rings or valve seals? I just started rebuilding own gen4 to prep it for a future mk1.5

[@Doc_Here]

For one it would be too much work to tear down to the pistons :) and toyota engines are legendary reliable so I trust it will be fine. I did not want to mess with the valves at the time as I was afraid to mess it up. The only reason I took head off was because an exhaust stud broke during disassembly so I had to remove the head to bring it to a machine shop. Then came these series of events you see in the video

@@Doc_Here Makes sense, thanks for responding so quickly. One other questions I mentioned in another of your videos, which manual did you use for instructions/torque specs? I have the link with all of them but curious which one you used? St205?

Man i really love to watch the whole episode but i just cant take it.i get sooooo dizzy with that camera mounted on your head.

Yes that is a fault of my early videos. Even I had trouble editing them. I got a better go pro that has a more advanced stabilization feature which resolves this issue for the most part.
