P38A Cavity beneath Bosch V8 lower intake?

Hi, so I did a stupid thin today on my 1999 P38 with the 4L Bosch V8. I dropped a boot through one of the holes in the lower intake manifold:

They just seem to be drainage holes for water? What is beneath this lower intake manifold piece, just an open cavity? Basically, how bad is dropping a bolt in that hole? Am I okay to leave it there or is the lower manifold coming off?

Thanks!

Underneath the lower intake manifold, is the valley gasket, that's all

Interesting LPG bypass !! Probably need something better than those bolts, or you might suffer air-leak & cause wrong fueling.

i would have to retrieve the bolt, but thats just me.. magnet on the end of a zip tie or bit of wire should poke around and find it. the gasket isnt flat, so the bolt should roll to the centre..ish

Well I discovered that the valley is indeed open, at least at the frond end. Just take the radiator fan off and you can stick a magnet in there. The bolt was easily retrieved this way! And good thing that I did because if it would have come out at the front end it would have fallen into the auxiliary drive belt.

Happy days!
