(87 GN) So I just noticed a knocking noise when I lightly rev the engine. When I pull off cylinder 6's plug wire the noise goes away. I am guessing it's a rod bearing since removing the plug wire gets rid of the strain on the rod. What do you guys think?

Probably going to pull the engine and go through everything as the car sat for some time. Just getting opinions before I started opening it up.

i dont usually pull plug wires but instead pull the injector connector to drop a cylinder
just pullng the #6 plug wire could also affect the #3 cylinder but running it more to test wont make it better and could end up doing more damage to the crank whick could render it unusable , best is drop pan and inspect but the end result will usually be pulling the engine anyway so prep for that

Cut your oil filter apart

Ended up being #6 rod bearing as I thought. Crank is coming out to get turned. Was hopping the crank would have been fine but it is slightly rough.

You might be able to polish it to .001 under.
