hey guys just wondering if anyone can help, have a weird grinding noise coming from the intake manifold runner bank 1 or potentially the harmonic balancer, so long story short I got a code after switching out to an external waste gate set up (intake manifold sensor bank one stuck open) I went to change the sensor and the bolt snapped off so now I’m doing tgv deletes, to bypass all this (yes I’m aware I’ll need a tune etc) just wondering what causes this and if anyone has had a similar issue, car idles fine than a 3-4 seconds in it makes a horrible grind/ clunk near the intake manifold, any help would be a appreciated as I’m pretty stuck atm
