Ok, so the other day i was out driving, launching the car at 10psi on the wh1c, and one time, the timing belt slipped, and the oil pump got out of phase (everything else was still perfectly in time)
I drove it home (2 miles) and parked it, then retimed + tensioned it w/ another belt and new tensioner. The car drives fine, i just put ~70 miles on it, but in the last 10 miles or so on my way back home, this noise started to get louder, to what you hear now in this video.
The engine was pulled out of a 99 GSX Auto, stock cams, arp studs + hks timing belt, balance shafts are still in it, and it didnt have this noise up until the one launch. I also did a compression test on it, and it got ~160 on all 4 cylinders
Ive looked at the harmonic balancer, that is in tact with no issues, all belts have tension on them, and the timing belt tension is within spec. there does seem to be a little bit of an exhaust leak between the manifold + turbo, however the sound seems to be more internal than a typical leak, but then again - i am asking you for advice!
