Posted end of 2025 but video clip wasn’t long enough. Old post here https://www.reddit.com/r/WRX\_STI/s/Kkvv0Pjl5E

I check the timing which was fine.
When I I ran a test start I could hear some sort of clunk sound then the car idle fine and slowly started making this sounds again.

Any ideas.

Thanks all
