RS6 up for sale on eBay

[4.2Crew]

Conflicting descriptors. Spark plus can't blow out a piston. Pistons don'e have threads. If I was a betting man, what you are describing sounds like a spark plug blew out of the head and stripped the threads. This is entirely possible and is also repairable (Helicoil kit).

That aside, how come you haven't disclosed anything on the auction listing? The listing is void of any description?

In the auction description as of 10am CDT yesterday (3-12-17):

"For sale is a used 2003 Audi RS6. The car is in excellent cosmetic condition, and has been maintained and serviced regularly according to the factory schedule. The engine is damaged (a spark plug blew out a piston) and the engine needs repair as the car cannot run as it is.
This would be an excellent donor vehicle for anyone looking to do work on an existing RS6, or looking to make upgrades to any C5 A6. Additionally, if you have the money to repair the engine, it is a a fantastic car."

Since we're critical of anything less than absolute exacting semantics/descriptions, perhaps an explanation of a spark plus is warranted???

...A spark plug blew from the #3 cylinder of my high mileage 1986 Yamaha FJ1200.... Not sure if spark plug debris or threaded debris from the cylinder head caused cylinder wall/piston damage----either way, compression of damaged cylinder only recovered to ~80% after helicoil and required cylinder/piston R&R.
