Well, the motor is assembled now. finished everything this weekend as i planned. good progress so far!
step one of reassembly was to clean these valves and let me tell you, nothing labeled "removes carbon" "carbon cleaner" works. at all. like 0. not sure what kinda carbon they test these chemicals on but they dont work for shit. i wasted 25$ on brake clean and seafoam. it was a bit of an experiment, i wanted to see which would do what as they both claim to clean/remove carbon.
seafoam on the left, non-flammable(doesn't evaporate as quick) brake clean on the right. valves soaked for 1 hour.
seafoam did nothing. literally nothing. brake clean actually started to work a little as i could see the carbon thinned out a bit. either way it wasnt happening quick enough for me and i was dead set on getting this done.
Friday i spent 9 hours in the shop cleaning, cleaning every millimeter of RTV off the block, off my timing cover, off my oil pan. many visits to the parts washer(such a useful thing). Before i went on my cleaning rampage i had to find something that would actually work for my valves.
Behold, the worlds best kept $6 secret.
soaked the valves for an hour in this shit, and the carbon was literally JUMPING off the valves. little rubbage with a mild scotch brite pad and some spinning in a drill and the valves were mint after an hour. this shit is SERIOUS. it just smells like pure chemicals, its hard to breath, its bothers your eyes, but it fucking works and the can is still half full. damn.
really nasty stuff, comes out like a foam, turns into a gross goop. you can see the final product in this photo also

CLEAN. good to go.
next we lap, and not the kind of lapping we usually talk about in this thread

simple process, nothing to it. takes some time but not really much. all valves were done on the intake side. exhaust side i didnt touch, just swapped he springs.
Done. getting 32 keepers uninstalled/reinstalled was terrifying. theyre tiny, they go everywhere, they cost like 9$ cad each, and they take forever to get. thank fuck i didnt lose any. its all i was thinking about.
after this, i bathed the head in the parts washer, then again with brake clean and onto the block it went.
The motor had ST head studs in it, but i replaced those with mazda OEM studs. good enough for the power im after. Torqueing was simple, but sketchy. these are stretch bolts so they only call for about 35ftlbs followed by TWO 90degree turns. thats the scary part. but got it done, onto installing buckets, cams, and cam caps.
heres how i kept EVERYTHING organized. also noted which bucket came from where so reassembly was quick and painless.
timing tool installed after buckets and cams went in.
installing the friction washers SUCKED. i was sketched out the whole entire time. got them on without too much drama, and without touching them directly on the flat surface so that was the goal and it was achieved. guess we'll see if they hold or if im doing a new build next year
after timing was done it was a quick spin of the crank to make sure nothing meets in the middle...and nothing did. so WE GOOD. WE DID THIS. I did this lol.
timing procedure was fairly painless, between using the manual, common sense, youtube, and
@JohnnyTightlips thread for some final reassurance it was smooth sailing. really took the mystery out of timing this motor. With the cam plate and the crank locking pin its pretty simple! the real key is to leave the gears loose until you release the tensioner. then you can torque the cams.
Also took the time to WELD my crank pulley. there are reports of the timing teeth slipping in relation to the pulley and that sounds like hell to diagnose soo....yea. welded that up.
and this is where we leave it. i have some great build footage im still working on editing and whatnot but yea motor is buttoned up valve cover to oil pan now. just needs accessories and thats about it. i need to get my injectors cleaned still, as well as some CS or overspeed seals. plan is to begin swapping in December and be ready for first start on new years eve. Lets see if i can make that happen.
