Well today I was offered a free engine and I went to go pick it up. It appears to be a Buick V6, I see some red paint on it and it's distributers up front. The guy who sold it to me told me it was in a Cutlass from 88, that he took out because the engine was making a ticking sound. The man also said that the owner of this motor before him had just rebuilt it. Looking at the engine, inside the valve cover the damages on The Rocker shaft. It's cracked right in half, when I asked him about this he said that maybe the timing was off or something it. Anyways I got it for free what do you guys think cause the rocker shaft to break.
