Hey all....still a bit stuck after some penetrating spray, and a bit of belting.

Crank is off, you can see here:

Block n pistons

More of the process to get to here has been documented too...just for the hell of it.

The engine strip down

I'm going to get some wet n dry sandpaper and try and get rid of a bit more of the rust that way...then see where I stand.

Appreciate the help.

Turn the block upsidedown drop some dryice into th skirt cup it may help shrink the piston enogh to delodge it after a good soaking in crc or wd 40

take the crank out.

beat the sh1t out of the piston with a rubber mallet.

and for god's sake, if you don't have one - don't hit it with a normal hammer. use a block of wood or whatever.

:edit: oops - i just saw b310gx's post. sorry...

I agree.. Drench it in CRC or WD40 and leave it for a day, maby two....

i agree,let the bores soak in penetrating oil
overnight.when you go to remove the pistons,turn the block upside down & tap the pistons out with the handle of a hammer.that is,hold the head of the hammer(lots of h's in there),in your hand,then tap down.if the pistons dont come out easily,get a piece of wood & put it on the piston,then hit the piece of wood.don't ever hit the piston directly with the hammer head,even if you're not planning to
reuse the pistons.

hay ther mate..
a hone probly wont help u mutch coz u will hit the pistons and mybe damage the hone depending on wat type u get.. i recon first try spraying all the bores with WD40 or sun sort of penetrating lube 2 brake down the rust.. spray it and maybe even leave it over nite and try the next day...and just make shor as u push them up from the bottom the rod duzn get stuck.. suntime u have 2 tap the pistons up with a dolly or soft hammer...

Hey all,

I've been stripping down an A12, to then put back together again - all as a learning process.

Now I've come this far I'm considering rebirthing it. New gaskets, clean up all the old parts....

The probelm is the cylinder bore is a bit rusty and the pistons are not keen to come out of the block.

I thinking of buying an engine cylinder hone today to rip out all the rust....what I'm wondering - is there a better way to get these pistons out?
