Thanks! I found a single piston on eBay: http://www.ebay.com/itm/Volvo-Brand...r_Truck_Parts_Accessories&hash=item27e1916cd1
But it doesn't seem like a very good idea to replace one, although the other's only have ~20K miles on them.
The block looks very good, plus it's an overbored B20 to begin with, I'm not going to touch it. Bearings looked good on the only one I've looked at so far (#3). Lifters all looked good too. Dunno, I'm half tempted to just stick the single new piston in it (after balancing it with the other pistons).
If your happy with cracking cast pistons---which is exactly what I'd expect on Volvos with those drilled oil returns under the oil ring (as opposed to the T slot design on oh, say OEM Mahle for the Ford V4/V6 fambly where I'd expect to drop the entire top of the piston off from crack propogating from end of oil return slot down to pin bore) then by all means stick just one in.. nothing wrong with that at all and lucky you found one....and an OEM one at that,,
I would kinda confirm what dish depth and diameter your really are and what the new one is..just sorta sayin.
Of course you know what would really wake up a nice n.a. motor like you have, but don't think of saving 450g per hole of ugly useless reciprocating weight...
