First, I know UTG has been wrong on a few topics, but it's usually minor or is corrected sometimes. I don't agree with everything he says, so most of it is entertainment to me.
Second, He never said the timing chain broke.
Third, he said that he could be wrong and it's just his assumption of what may have happened, which was the timing chain being too tight that could effect things.
Fourth, whether it's intended or accidental you are putting words in someones mouth when you rely on your misunderstood memory. Even I need to fact check myself sometime so I don't make false or misinformed claims. And remember, there are other content creators here, you could accidentally make false claims about them too.
