So I tried the infamous seafoam the other day on my 98 4.0 to try and get rid of my slightly sluggish low end. Got a little smoke, not much, but I noticed it was coming from my exhaust/intake manifold area. So Im fairly sure there is a leak there. So before I tear it all off and replace gaskets, is it plausible that this is contributing to my loss of power and slightly lower gas mileage? ? Or should I not particularly care if I have a slight leak? Just trying to save myself some work if it's not necessary. Thanks.
