Seems this has happened to others too. Both motor mount bolts are broken flush with the block on the passenger side.

1999 5.0, auto trans, rear wheel drive.

It looks like I have a straight line to get a drill and easyout to them. I'll lift it from the top as I do have an engine hoist and this will give me more room underneath to work in.

Anyone have thoughts as to why the factory bolts snapped off or suggestions that might make this task easier?

I have one snapped off. I didn’t fix it. I don’t drive the truck hard at all, no problems as of yet.

That said, I would probably try to build up a nub with MIG/stick and then weld a nut onto that, and extract it that way. It’s tight in there, but looks doable. The block is cast iron, and I’ve had great results pulling steel fasteners out of cast iron this way. I had a starter bolt snap off below the surface. Was able to build it up with TIG (lift start works well, had enough access for a TIG torch) and get the nut welded on that. The welding gets the bolt cherry red, which helps with extraction.

Easy as pie if you pull the engine, but that’s a PITA

Thanks for the suggestion! I do have a wire feed. If this engine comes out it is getting rebuilt as it has 230k miles on it.

Interesting that your one or my two snapped off.

I suspect that my truck was involved in a front end collision and rebuilt. I think that, coupled with corrosion, may have contributed.

My '99 2WD 5.0 has this issue on the passenger side. Since (at the time) I planned to pull the engine in several months I just chained it down on that side. It is on an engine stand now, awaiting installation into my '73 F100.
The engine has yellow markings on all the major parts so I assume this is a junkyard engine. I assumed someone was in a hurry and used an impact to install the bolts.
