So....I have a Briggs 18HP opposed twin that I'm trying to remove the mufflers so I can install an exhaust manifold that is specific for a tractor the engines to go into (my Steiner). Three of the bolts (cap screws) came out pretty easy. The fourth one is fighting me, it's in a spot where I can't get on it with my vice grips very well. I've tried the normal stuff... (1) PB Blaster. (2) Tapping on the bolt with a punch & hammer in hopes I can break free the corrosion. (3) Heating the bolt. (4) Heating the block....aluminum, so very lightly. (5) Various angles with vice grip hoping to spin the bolt out. (6) Swearing & repeating steps 1 through 5. Anyone have any tricks they'd like to add for removing a stuck or seized bolt from an alloy engine block? My next thought is to remove the top of the cap screw, remove the muffler, hope there is enough of the cap screw left behind to get vice grips on & remove without the muffler interfering. Offending bolt in pics.
