I took the valve cover off of my 99 xk8 as I wanted to check the valve cover gasket as I had a small leak. In the process of removing the valve cover 7 of my valve cover bolts fell out and onto the motor. I managed to find 5 of the 7..... I cannot locate the last 2. My question..... Is it possible for the valve cover bolts along with their rubber washer and sleeve to make it down to the oil pan via the cam chain tunnel? I can take the oil pan off but I don't want to do that if there is no possible way for the bolts to make it down there. I did check the cam chain tunnel with a camera and didn't see the bolts.

Thank you in advance.
