Previous Owner Broke Valve Cover Bolt

My buddy bought a 2005 F-250 6.0 last month. A local dealer was dumping it off cheap cause his "mechanic" suspected it had bad Headgaskets. Headgaskets ended up being fine. But this truck is a basket case!

Back to the problem at hand.

I did an oil cooler for my buddy cause his deltas were a little over 15 degrees. I noticed the drivers side valve cover was coated in RTV. So I took the valve cover off to inspect the situation.

One bolt was lost and a new coarse thread bolt was forced in so that hole is all messed up.

Then I noticed that the bottom center bolt was not there and just RTV'd over top. When I pulled the "RTV plug" that had for formed in the hole out I saw that the previous owner had broken then bolt off and poorly attempted to drill it out.

I'm at a crossroads here if what I should to to repair this issue. Try to drill it out and over size it? Just RTV back over the hole like the previous owner and hope for the best?

Keep in mind this engine was caked in oil and sludge. I spent nearly 8 hours scraping and scrubbing to remove all the oil and sludge that was all over the engine. So I'm hoping for no oil leaks when I put it back together.

On a side note I was planning to post the tear down pictures to show you guys how bad it was. So many bolts loose, finger tight, over tight, so loose they were just laying next to where they went as if they had vibrated out of their hole, etc.

broekn bolt

So what did you end up doing with the snapped off bolt?

I just broke the 12mm bolt where the FICM mount attaches in the back of the left side valve cover.

Personally, I would get a right angle drill (or drill attachment) and drill it out with a small enough bit that it wouldn't damage the threads, then use an Eze-Out. I've had decent luck with that before. If that doesn't work, just drill and tap.

Something you may try, depending on the angle it snapped into, is taking the valve cover back off and trying to get a bite on that bolt. There shouldn't be tension on that bolt anymore, so it may come out easier than you think.... may being the key word.

You might get lucky with a left hand drill bit. But first use a center punch to make sure you're centered on the broken bolt.
