Hey everyone, I changed out the spark plugs yesterday at 157k. OEM densos in dealer packaging. Last known work on the engine was indicated by a marking on the fuse box with "tune-up 65k" which may or may not have included the plugs. Otherwise I have no idea about previous maintenance. There was a weird ticking noise that went away after I put the new plugs in. It could have been coming from the PCV hose which I put a zip tie on because the old clamp wasn't tight enough.
Heres what the Autolites looks like after ??? miles.

Is there anything wrong with the engine by looking at the plugs? When I pulled the plugs there was a lot of black grime that I wasn't able to clean because most of it would have gone into the cylinder. Left it undisturbed. Also all of the plugs went in easy with the rubber hose about 1/4 to 2 turns. I then tightened them with a torque wrench. One of the plugs took more power to torque down at the end. They all have little gaskets and I put very very little antiseize. Did I cross thread or was it a tough gasket, or the grime? Its got me worried
