2G What’s this sound

[98gstJames]

Alright so I just got my car back from engine builder and dyno last week and everytime I start my car and it’s in low rpms I can hear this clacking noise, I’m not 100% sure if I’m just tripping out and this is normal or what but I just wanna know what you all think. I’ll add the video.

I feel like I've heard that sound before. I'd check and make sure nothings rubbing against the timing cover. I'd also check your timing belt tensioner.

Timing cover was definitely one of my thoughts, just wasn’t sure if the sound was something to be worried about

Sounds like an exhaust leak. Definitely hearing some lifter tick too but that’s unrelated.

Most definitely have lifter tick just wasn’t sure if the other noise was something I should be worried about or not

Here’s a little bit more straightforward video of the sound right on cold startup

Possibly bad timing belt hydraulic tensioner. Shouldnt have any play in it “by hand”
