2011 Yukon engine dropped a valve... 186k AFM Flex

[Geotrash]

I bought a 66k mile engine from American & Import for $3200 with a 6-month warranty. Haven't torn down the old piece crap GM 6.2 liter yet. Keep the engine oil changed frequently. This Yukon was used went we bought it, really no maintenance records and obviously the oil was not changed!

Awesome - sounds like a fair deal and a low mileage engine. Hope this one lasts a long time for you. Thanks for the follow-up.
