Re: Duramax Buy Back
My neighbor works at a very large GMC dealer---said its about 400 or so vehicles affected so far --its the L5P engine i think he said--- problems with engines hydro locking or leaking head/block issues--- Aluminum heads don't mate properly with block causing coolant leakage- and or the blocks are bad castings-- That engine it's a collaboration between GM and Isuzu--It's not the head gasket its the block and the head themselves--- cheaper to do a buy back than it is to replace the engine for $15-20,000 and hope you got it right--- kinda like what Ford went thru with "their own" diesels in the 04-08 after they stopped using the International 7.3's--- FED 387
