Ran sea foam in crankcase for about a hundred miles then changed oil and ran 1/3 a bottle through the pcv with engine at idle drove for a day about another hundred miles and ran another 1/3 of a bottle through the pcv again. Idle and acceleration is much smoother. Still getting strong smell oil in exhaust when i gun the throttle. Also does anyone else vx rev really high on startup. Like 1500-2000 rpm for a minute or so then goes back down to normal 700-900. I still have to replace manifold gaskets. Not really leaking yet but around that time. Scared to see what I find when I do.
