M6 x 35mm Bolts found in Cowling with 9.8 marking on head?

UPDATE: Well folks, these DO originate on the engine, and they aren't supposed to be loose inside the cowling, either.

Part# 893754035 (2 per cylinder head, very bottom). Four used on each engine V6/V8/V.....

Almost impossible to access without lifting powerhead, though.

Not sure if you are speaking of the skirts or engine cover when you say cowl. You may want to check the bottom end of the exhaust pipe. You have to take the side skirts off. A few guys have found these bolts backed out and rattling around.

Pulled my chaps off to check the exhaust pipes and found a bolt that looks like the left one in photo. It was in the pan so it was not from the exhaust pipe and they were all in place.
How critical is this bolt?
Should I be concerned?

Wouldn't cancel the day trip for it, but I WOULD plan to get it properly installed soon (Engineers wanted it there for a purpose).
