Frame bolt missing

Hi everybody,
today, I've made a little servicing because I had a little water leak, so I've seen, surprised, that one of two right frame lower bolts is missing.
Do you think it can be happened because of vibrations?

NO, it was only loose! If bolts are turned with Loctite, they never fall out! Those main bolts is one "maintain work", so they should check sometimes... Btw, those bolts are "special ones" with not normal threads and special lenght also. Btw, where You had liquid leak??? Very many 907 engine have had that in front sylinderhead/o-rings. Like i had also

Ok,
tomorrow I'll buy another one and then I'll tighten it with the Loctite 212.
I had some liquid leak near the reservoir 'cause the clamp was loose.
I think I'll have to replace the T hose.
Besides, I have to straighten the right radiator support.
The previous owner did fall down, so the rigth side has been repaired, but it don't like to me.
The radiator support also holds up the headlight frame, so the headlight is not centred in the fairing.
Any advice to straighten it?
Ciao

Mine leaked from the front cylinder but it wsn't the o-ring, it was a loose plug on the cooling passages. We call them "freeze plugs" in V8 blocks but in fact I think it's there for machining access...

Finally, I've found the right bolt.
Can you tell me about the torque (it's right 4 - 4,5 nm.?) and the kind of loctite?
I don't want to loss it twice.....

What's the bolt diameter?

The head of the bolt is 15
I've seen on the manual that the torque would be 4 - 4,5 kgm.
Could you tell me about the need of the loctite or the kind of loctite?

Loctite 243 (catolog number 16793)

Or,

Dunlop SAS 116 Thread lock function well
