Just wandering if your rappy is stock or has it had any mods, pipe j-kit etc. The engine problem that you are describing is usually due to running the bike in a lean condition, this sometimes doesnt show up for some time if these mods were made and not tuned properly and a lean condition is present it can break a ring land and is the usual suspect . Oiling problems usually affect the bearings in the engine more than the ring area of the piston.

Why would the engine need rebuilt if only the head gasket is leaking? Just asking......

If the quad revs up then you have a leak in the area and should more than likely to a full head gasket and piston ring rebuild.What kind of oil have you been running? If you engine crapped out after only 3 years I would switch oils....

i agree kill the easter bunny he is a muntant....lol. as far as the raptor sounds like u ride it hard....bearings need redone about every 3-4 years in our situation. sorry to hear bout the piston and the problems it caused i know first hand how expensive that is...just bear the cost because i am sure that u had lots of good riding before and will again....just be glad u dont have to go replace/upgrade $18,000 like i have so far.

The only mods I have are a full CT exhaust (with jetting to CT's specs for where I usually ride) and a K&N air filter. The guy at the shop said the engine probs could have been caused by dirt getting into the engine through the air filter, but I do clean it regularly and it has a pre filter on it so I don't think that was the issue. The other possibility he came up with was an over rev (maybe while jumping?). Again, I can't imagine that was the cause since my 230lb butt is usually not jumping.
