Did you try like maybe taping a towel or something right up there? Problem is it's awfully close of your belt if it falls not sure if you should try. That way if towel is wet soaked and it doesn't leak it could give more clues or something IDk haha. It does seem like it starts right there between the head it's strange. |

And if you put your finger there you don't feel the oil coming from the lip like towards the left or right? Maybe it's leaking from elsewhere and it follow the top of the lip so you don't see it and then it drips there. |

Thoroughly clean off the oil and any residue in that area with Dawn dish soap and water and a paint brush to get in the nooks and crevices, rinse well, and blow it dry (hair dryer, leaf blower, etc.). Now lightly dust the area with talcum powder or flour and go for a short drive. The source of the oil leak will then be readily apparent.

Bolt/s would've either snap off or strip the threads into the engine block before cracking the block to cause leak. I know you don't want to hear it but is probably the OFH. Did you replace the bolts and properly torqued them last time?

I believe there is a procedure in ISTA and/or INPA to test the car and make it hold*/do boost. Maybe you could try that to give you more idea or see if it will leak. |

I ordered new bolts there coming in soon, i will torque them properly, and I torque them before to on my last attempt, but it’s still hard for me to believe the bolts need to be replaced, there steel kinda crazy and plus if it was the OFH wouldn’t leak above that lip then down? I’ll show a picture
