Let's stop this nonsense. I think both of you guys need a break.
Rick, I think if you thought about it, you could find where you appeared to be a little over the top with your tone/comments.
BH, the simple solution to replies that you don't like, is to ignore them and focus on the replies that interest you. Instead, you're throwing an endless amount of fuel around.
With that said, Engine problems can be a frustrating time. I am glad you found the real issue with your heat exchanger. Hopefully that will completely solve this for you.
Cheers.
