Just through break in on my 454 for my lst2. Probably 10 tanks. Ran about 200-230 during break in. After I finished and started tuning it a bit, the engine started over heating with tons of smoke coming out still. So I decided to tare it down and seal it because I was too lazy to do it from the start I opened up my engine and it looks like this. Why/how? Does it mean I've been blowing a lot of unburned fuel through? Blue Thunder 20% Sport

its because your fuel is blue...some fuels will do that

Yeah, I use BT. But it's never done it on any of my other engines. Is it anything to worry about?

I have never had it happen but I use a diff fuel but I don't think I would lose sleep over it
