The lifters are solid on VQ engines, actually "valve tappet buckets," so I doubt they would have got damaged. I suppose a valve could have got vent. Most of the time when these converters break apart and cause damage, it's only very tiny pieces that get sucked back into the combustion chamber which gradually score the cylinder walls over time until they start burning oil. Has the engine been making a "whining" noise prior to this? Upper timing chain issues are fairly common on 05-10 models due to poorly stamped chain links, which cause the chains to cut into the plastic tensioner faces until they start riding across the top of the tensioner plunger. Eventually, if left unfixed, it could cause the timing chain to jump.
