Hey Guys!

I getting ready to begin the engine tear-down now that I have more time on my hands. I have purchased the gasket kit, oil seal kit, impact driver, and JIS screwdriver set along with Bill Silver's Manual. Are there any other manuals/parts you guys would recommend I get before I start getting into the engine? Thanks!

Hey guys!

So, now that I'm out of college for the semester and have more free time on my hands, I've started rebuilding my engine! It looks surprisingly clean inside as well considering how rough the exterior looked so it seems like it will be a good candidate for the rebuild :)
Unfortunately, I hit a stopping point earlier than expected...some of the screws are practically fused to their counterpart from corrosion/time. I soaked them in P'Blaster, Liquid Wrench, tapped around with a rubber mallet, and used a handheld impact driver (which I'm not totally sure is working properly) and still nothing. Does anybody have any suggestions to getting these things out? I need to get them out to move on to removing the rest of the top-end. Would like to avoid drilling them out but I'm running out of ideas. Thanks in advance as always :)

Some propane torch heat to the part with the bolt hole..
On screws a few good smacks straight on with a Philips bit and a hammer might break the bond. On bolts a flat faced punch and hammer.
Air impact wrench.
If you heat the aluminium then apply Liquid Wrench it helps draw the liquid in.
I usually do that, then apply the pen. oil a few times and leave it for a few hours or overnight.

Yeah I was gonna hit it with the torch but was kind of reluctant to do so since it was covered in chemicals. I guess that's my next step though. I also think that the PO may have swapped the original JIS screws with Phillips in that one area since a #3 Phillips fit better, because of that, the thread pattern may be different as well causing even more difficulty to get out. Will try the torch and let you guys know how it goes, will also start a new restoration thread once I make a little more progress.

Any more info I will need to prepare for is welcomed as well, thanks again!

The 6mm screws/bolts are regular 1mm pitch.
The 5mm are JIS (0.9 pitch as opposed to 0.8).

Good to know, thanks R100!

Also, my next problem to tackle is freeing up the frozen pistons. I sprayed some Pb Blaster into the cylinders but so far that stuff seems to not be doing too much for me. I read that automatic transmission fluid works well? I've also heard gasoline too. Does anybody have a suggestion that they have maybe used to free up their pistons?
