Thanks. I appreciate your thoughts. He explained it to me when I picked the the engine up. He said that when they were test running the engine, they monitor temperatures and noticed that it was running too hot. They then determined that it was a clogged j head, so they luckily had an exact date correct j head in inventory to swap it out with. He said that they still had no idea where or why mine was blocked, but that after swapping heads, the temps were good. He sent my old head home with me.
He seemed as surprised as everyone ok here that it could have a clogged head. I have no idea if it should have been caught by them during the reconditioning of the head, long before the test run of the engine
My hopes are that the heating up won’t be an issue, or he would have just swapped heads and not said a thing to me…..if he felt that it was their error and that the heating up may cause issues in the end. I dunno. Not much use stressing over it, I guess. But the “doesn’t really come with a warranty” definitely worried me. When I acted surprised at that comment, he said “well if there are ever any issues, you can definitely come back to us and we will take care of you”
