740 rattle noise on deceleration

One mechanic says 'wrist pins' on one cylinder.

So you mean ask them to partially dissassemble, with the used engine
waiting in case it's unrepairable?

 

Well I would do it myself, whether they should do it depends on the
cost/time involved. If the rest of the engine is in good shape, this is
something that could be repaired, but if a new motor is cheap, it's
probably cheaper to have the whole thing swapped. I'm curious though
because I've never seen a wrist pin fail in one of these, not that it
can't happen, I've just never seen it. Maybe an oil passage got clogged?

 

Thanks. Hmm. seems I'm caught between a mechanic who comments but
doesn't want to do the work, and another who may mainly want to sell
an engine. Any idea on how to unearth a local mechanic for another
opinion? These two are the main show in town for volvos. Haven't
tried the dealer. Should I? I always assumed they'd be less
interested as I didn't buy from them; bought it used.

Don't even talk to the dealer, they'll try to sell you a new car, or
give you the option of buying a new engine for somewhere around $4K plus
installation. They have no interest in working on a 20 year old car.

Got any gearhead friends you could pay in pizza & beer?
