Hey Everyone. I've got a TL130 w/ about 1,800 hours on it. It's been running a little rough lately so i took it in to get serviced. The local shop is telling me that there's a small crack near the air filter, which means that dirt has been sucked down into the engine and they're recommending we need an entirely new engine (about $12,000 with labor). This seems to be a bit excessive to me, has anyone else had a similar issue? Are there any alternatives? Any advice would be greatly appreciated. Thanks.
