Dropped Engine
Ya know, the part that sucks about this is that you have to trust them to do it. (whatever it is)
I personally would never accept an engine that was dropped due to the stress put on the bolts and gaskets alone, not to mention the balancer and crank getting slammed.
I think I would ask for a complete tear down, inspection/magged and reassemble with new gaskets.
Once the heads are torqued and it lands on the head you know it has to put a heck of a shock on the bolts and gaskets.
Now that being said, if I was a racer and my engine got dropped possibly ruining my season and also possibly doing some really expensive damage if it came apart on the track, I might even be more serious about it.
Thats a hard call.
It sucks, but they dropped it.
