When I split the 12.5 hp Briggs to change the crankcase gasket, I noticed two of the bolts weren't tight. A Google search tells me this is a common with the engine (aluminum block & steel bolts). Assuming that is correct, which thread locker would you folks go with: blue, red, high temp red, etc? What would you use for the engine mounting bolts, some of which where also loose.

Briggs 12.5 hp, vertical shaft, model 286707 0441 01.

The next guy that takes those bolts out will not like you if you use anything but blue in aluminum. Lol

That's mighty unusual. Usually steel bolts in aluminum threads manage to lock themselves very well when dry. I always put antiseize on them so maybe there's a chance of getting them loose the next time.
JMHO,

Well it is a 12.5 Briggs, the last three I had, including a 11 hp all had the pan bolts loose or completely backed out. I think this is common on the smaller hp vertical briggs

Yes, the Briggs 280000 series replacement bolts now come with blue thread locker applied to them & instructions to up the torque to 200 inch pounds. Seems they feel it is pretty "common" as well.
