Just did intake manifold gaskets to try to resolve rough idle. Initially forgot to tighten down EGR... Now the engine seems smoother than ever, but on my final go around I pulled out the stethoscope. When I put the scope on the valve cover by cylinder 2 I hear a loud knocking sound like something banging into the valve cover. No noise when I listen to the oil pan and block from underneath (not rod knock?).
The lifter valley was full of ash/carbon/sludge that I vacuumed out during the intake manifold job. Do I perhaps have a sludged up lifter/pushrod that like marvel mystery oil or techron will fix? Should I try to adjust valve lash? Its not my daily driver but I don't have the energy to pull an engine atm.
