Posted originally in the 80s section but a lot more 3FEs over here just did the head gasket after it giving out on the highway due to a faulty thermostat led to a failure of my radiator sounds like a turbo I wish I had. Video link in the original post.

Sounds like the air injection manifold or one of the air injectors is cracked. Start there.
 
Take the belts off and start it up. See if it's coming from the air pump.

FYI I used to run a shorter belt on 3FE, to not run the air pump. But it would not pass emissions like that.

I think you win sprayed some starting fluid near here and got some effect and could see it blowing back will have to dig in some more next weekend
