Jesus Christ bro are you talking about the 3 bolts that hold the passenger side cv shaft to the block? Like half way down the shaft? IF SO it sounds like they pierced your block and you're losing oil pressure and have created a drain plug where you really need those bolts holding that shaft in place.If they did that.They need to fix it. Dont overheat the car it can be fixed in my opinion in different ways but holy crap it's their fault and they need to replace the entire block or get it fixed.Good luck I might be wrong I am not there in person.
