Starclear 1200 dome rises after turning on pump.

I have an old Hayward Starclear filter housing. I noticed recently the dome lid was cockeyed when I went to clean the filter. It wasn’t leaking but it definitely wasn’t flush on one side. I chided myself and cleaned the filter, put the lid on and tightened til it stopped. Dome flush. Kicked the pump back on and it did the same thing. Read some stuff. Replaced the knob. Screwed it down flush. Same dang thing. Took some vice grips to the tie rod and it’s in there very tight. I am remiss to try to tighten it further, but I can’t think of any other piece of the geometry here that lets the lid not be flush. All I can think is that over time I loosened that rod a bit here and there with a crusty old star knob grabbing it a little too hard. Any advice appreciated. It’s not leaking, and the gap on the high side is > 1/4”. But I can’t think this is desired behavior. Also, are the tie rod lower threads standard or reverse? Seems they should be standard but I’m so confused here anything is possible.

Thanks!
Chris

Things wear out.
Time to replace the filter.
