k, hg was done at dodge 4k ago, stil smoking blueish and smells like ass..the idle is semi ruff at a little below 1k things i did to fix: new egr, plugs wires cat sea foam doe did comp test, 180 across, i just did one and its still 180's across the decked the head when they did the hg, so im thinking my valve seats may be bad, since i did comp test i can rule out my rings right? i have ane hg and head that im putting on, will this solve the problem based on the things ive tested and replaced?
