Today I was disconnecting everything from the 1.3L G13BA in my Sierra (I'm starting a coil pack Baleno conversion).
So far all the fasteners have come off cleanly, including the exhaust fasteners .
I got the driver side flywheel cover bolt off, but the passenger side bolt rounded off unexpectedly .
I cut a slot into the bolt head with a dremel wheel and have been striking the slot at an angle with a flathead driver and a hammer. This method has worked for me before, but so far it hasn't turned at all.
The rear of the thread hole is visible so I sprayed a bit of trans. fluid/acetone mix in there, but it still hasn't loosened.
Any suggestions on how to get it out?

Vicegrips on the head. It's generally a one shot deal so make sure the vicegrips are sharp and they go on very tight. Should move a bolt that's only 6mm.

Weld a nut on it

Six sided spanners can often grip rounded bolts.

Tried the vise grips with no luck.
I'll try to borrow a welder next

Filed down the sides of the bolt head and managed to get a much better grip on it with the vise grips.
Bolt now removed.
