Hi Ryan,
Since I'm advocating for the devil tonight, I thought I'd offer another view: I think, perhaps, they were fairly bright. And no smell of scam rises to my nose.
Perhaps these folks aren't as familiar with old volvos as we are, but remember they were not sure of the B230F's status as non-interference. Many of our newbies aren't either, because they can quote Bentley, Haynes and Volvo's own literature saying just the opposite - because there are those exceptions overseas. But, yes we know it is non-interference. I know personally that mine are, from having freely rotated both cam and crank untethered by a t-belt.
But, again, the shop didn't know. So before wasting the time to time (ouch) it, they rotated the cam by hand to close each set of valves and attach their leakdown tester to that particular cylinder - to prequalify the job. Probably it is standard procedure in this age of crashable engines.
They didn't find a bum roll pin (they'd feel that) but perhaps any other cause for the loss of compression - gasket, dropped seat, maybe even, although I've never seen it in mine, a worn ring - to give hope to the oil squirt BK is suggesting. But the bottom line, is it didn't meet their prequal, and they have to believe the Volvo dealer when they provide the (false) information about the interference build.
