Back again with more KA24E problems

I just changed some seals and timing components on my 1990 240sx.
started right up except for the fact that it wasn't running on all four, so i swapped plug wires 1 and 4 and it runs on all 4 now, (which is strange because i never took the wires off the cap)
and so it's running bad, like laggy, not powerful like it did before,
and now there's like a metal on metal sound like a knock or a tick, like the head is being starved of oil,

anyone else had this problem before?

tensioner, guides and gaskets. i read replacing the chain was optional if the chain is in good condition, no cracks or anything,
i never removed the chain from the engine, or sprockets

So did you remove any spark plugs? Or remove the wires or pull the distributor cap off? It's hard to diagnose over the Internet, but ideas would be

Making sure the firing order is correct. FROM MEMORY I believe the top left of distributor is 1, then 3 then 4 then 2 when going CCW

Possible vacuum leak? Never know, may have split an old broken hose by accident.

Timing? Did you pull the distributor out to do any work?

Basically it ran good before? If it doesn't now, sorry but it's most likely something you did. Just retrace your steps an think logically and troubleshoot the problem. Did something not get hookedup ccorrectly, or in a rush was something forgotten altogether? When doing a gasket did you scrape all the old off for a good seal? Idk, just shooting ideas out

i re timed the oil pump, redid the firing order (which was way the fuck off i don't even understand how it was running) the tick got quieter and it's running better but when i set the ignition timing by moving the distributor it runs terribly.
just gonna move it so it runs good by ear.
i'm going to take the oil pan off and clean off the sump and stuff to make sure it's not plugged with RTV silicone,
i think i have it all figured out/
