I am doing an unexpected overhaul because of a couple
badly pitted tappets and a badly warn cam... During the overhaul I
plan to update the engine with higher compression pistons, and an ASI
performance Cam. these modification should take my 150hp O320 to about
170hp...

Once the engine was completely disassembled I started the cleaning
process... I bought some Mar-Hyde Tal-Strip aircraft paint
remover from
the local Advanced Auto and started cleaning... I just sprayed
it on, waited about 15 minutes, and then washed the parts down with a
pressure washer... This stuff is great! Not only did it
get all the paint off, it also removed all the baked on oil and
varnish from in side the engine... I used this method to clean
the case halves, accessory case, sump, cylinders, pushrod tubes, valve
covers, etc... Once the cleaning was done, I went to the bead
blaster to prep for paint (except the cases as they were clean enough
and I didn't want any blast media in there)... I then had the cases
reassembles by my A&P / IA, as he wanted to check it out... He
said it was in great shape and we could go ahead and use it without
spending the $700+ to send it off to be yellow tagged... The
faces were perfect, no fretting... The bore at the front and
rear was within factory new specs, and the bore at the center was only
.0002 out of factory new specs, and WELL within service limits...
The mains and rod bearings were standard size and the crank looked
like new... nonetheless, I took it down to a local machine shop
that came highly recommended by two A&P / IA buddies of mine to have
the crank cleaned, magnafluxed, the runout checked, the prop flange
checked, and for a light polish... I also had the rods
magnafluxed and checked for straightness... Everything checked
out, and the took the stuff back to my A&P for measuring...
Should be fine though with new standard size bearings...
Here's some pix of the engine removal and disassembly...
Here's some
pix of the cleaned pieces and the masking I did to prep for
painting...
I plan on painting the cases, sump, accessory cases, and
misc with "New Ford Gray" engine enamel that I got form Advanced Auto...
I will be painting the cylinder bases (steel part) black, and leaving the
heads (aluminum part) natural.....and I will be powder coating the pushrod
tubes, intake tunes, and valve cover black as well...
