Default Strange Engine noise, have video with sound

does anybody know what this odd popping noise is in the background? it kinda sounds like an exhaust or intake leak and is very apparent under heavy load (like accelerating) and goes away whent he car is warmed up. my guess is it's a gasket busted somewhere (the car is 115k miles).

i took it to the stealer and they "couldnt find" a problem even though i demonstrated it for them.

it's been driving me crazy for months.

hard to tell, but it sounds like it could be an exhaust leak. Does it "tick" when you drive it cold?

Default 2nd. seafoam just found my leak. ex mani to turbo gasket. no wonder my boost was flucuating..

I swore that I still had problems with my turbo to TP gasket but nope, seafoam proved me wrong. Picking up gaskets manana.

Exact same problem I just had fixed. Much quieter and smoother now.

Default this time I used two clear hoses, t'ed to a nylon boost line. sucked it up quick w/o chocking it

the T was like this one on the top left. the clear hoses were really loose on it so air could escape, and the nylon hose, I used a piece of silicone tube from a hosetechniques sample kit. It sucked up the SF quick and didn't even get close to chocking the engine. Worked really good, and the car feels good after cleaning out the foulness from a few 7e foulings

Default when i drive it cold it's a whole lot of ticks

they make the noise heard in the video. when the car is under load the ticks are way more apparent.
