Engine severe lifter tick/knock

[Moltinssj2]

Hello guys, I have a 1995 3sgt Dohc base yellow. This problem started when I changed both Valve cover gaskets. I did make sure to have all the bolts back where they belong. I looked up all 3s/Stealth forum and YT vids.l and came to the conclusion that it was a rod knock. So i did some research got the std rod bearing. Then i remove the downpipe,cross member and both trans support brackets to remove the pan. I found no flakes,no shavings.Removed older rod bearings they did have so wear for a 118,622miles engine. But all were in place and journal were shiny with no marks. So i plasguage old and new ones and everything is torque down to and withing spec and clearance. Got a another pick up tube since old one was dented and change it and undented the pan with some wood and rubber mallet. Took me more than a month due to shipping and stuff. Put back everything on and started and bam!... the tick is back at it again!!! I was so frustrated that I took a video,bathed and go to sleep on the middle of the day,Lol.
Any suggestion,tips and personal experience will be apreciated. Sorry for the long story,I have no body that know about these cars in my area.

sure sounds like rod knock. pull the valve covers and make sure a rocker didn't get knocked off or you didn't leave a tool in there.

It sounds like rod knock though because any valve train noise is half the engine speed.

Well,I already did change de bearings. The cams and rockers were in place,nothing was loose.

You dropped a plenum lock washer down the intake....

makes perfect sense. Didn't occur to me. Every time I pull the plenum I cover the holes and I check all six runners to be sure nothing is in them before putting it back together.

Damn,im gonna check that with a magnet,since i replaced the plenum m8 1.25 nuts since one of the washer got lost.

This problem started when I changed the old valve cover gaskets.I hope it isn't rod knock or bad lifters.
