    Hey everyone
    The motor locked up in my 2010 tundra 5.7 and I drained about 1 gallon of coolant out of the oil pan. I just had the air management valves replaced by a dealerdeale 3000 miles ago Could this have anything related to the replacement of the air valves? Or what would have been the cause of this the truck was running great no signs of overheating. This happened really quick.

    There has to be some sort of breakdown of a gasket or seal between the coolant and oil. Head gaskets are the usual culprit

    +1. Lockup probably hydrolock caused by coolant in one of the cylinders.

    Take it back to the dealer but watch/read about the AIP valve replacement process first so you have ammunition.
