umm im gunna have to say no to innovate doing that but you may wanna look into them possibly being snapped. if charge piping was to bottom out on the street or something its could very easily snap bolts. somethings gotta give. hopefully they were just loose and backed themselves out till they fell out.
That is a pte built turbo and could be the problem right there. This is a 30r compressor cover…
Your’s is more like this style…
It will be either 8mm x 1.25 thread pitch or sae. This is a PTE qc problem not Innovative. You should never have to touch those bolts they should have been locktited when the turbo was built before balancing.
Loctite will be fine on the compressor side of the turbo and most times you are better off with a proper flange head bolt than normal hex with split washer. You will get more holding power and the spring tension of the split washer desipates with time as well as the washer being split has the ability to move out from under the bolt and break the torque. In a high heat vibration app you want flange head bolts and nuts and next step is a tapered washer last step is saftey wire.
