siezed pistons?

[andy4200]

Just wondering... How hard is it to get siezed pistons out of a block.
I'm looking at a couple of RV8 engines for a little project but quite a few are siezed.
If it's doable then I'll probably take it on, but I don't want a huge expensive job to get it done.

Cheers

Depends on how they are seized, if the piston has melted and smeared itself all over the bore then you may need to machine them out. I recently stripped a seized Rover V8 ( see Rover V8 rebuild thread ) and it turned out that one of the pistons had simply rusted to the bore. I left it soaking in penetrating oil for a few days and it came out quite easily. HTH

Pour some hot oil in the bores. This should help free them.

I imagine you'll end up beating the pistons with a wooden drift and a large hammer...

It worked for my old 2 stroke Seagul outboard.

Good, at least I now know that they will come out somehow.
I don't need to get the engine working again just didn't want a few pistons stuck in there.

Thanks

Is this a table project?

Boosted.

Well figured out Holmes.... not difficult I suppose

I've had they threads bookmarked for about a year but never got round to actually doing anything about it. Now that they have resurfaced has just reminded me that I need a table for the living room and what a perfect opportunity it is to convince the girlfriend.
I managed to jigsaw through the current one by mistake, oops.

I hate the idea of using a perfectly good engine hence the question, and my garage is about to have a little more space for a couple of months.

I wonder if in ~20 years time we will be converting all those coffee tables back into ultra valuable 3.5 rover v8 engines?
