gretch no chance for a larger bolt as this is on a valve cover bolt.

get the dremel with a small carbide tip and work on the fat part of the stuck bolt try to grind down to the insert/head threads and see if the pieces of bolt will work loose stay away from the side thats into the insert, the dremel should do the job , you might want to have a helper with a strong vacuum cleaner positioned at the hole to suck up any particulate while you grind with the dremel

You said you have space problem, maybe you know this, but Timesert includes an oversize tap, should take out the threads. You end up with original bolt size. Much better than helicoil.

SharkSkin

Agreed, get a handful of tiny dremel bits and just work at it. Might want to play surgeon, and cover the entire head except the area you are working on.

Sorry, I thought it was a water bridge bolt.......... where did I get that idea from?????

Big Dave

Update: The bolt that was drilled slightly off-center is out. What's left is the original hole minus the threads (1/4" diameter). So...is it time for Helicoil or Timecert? I'm not familiar with either one, so which should I use? Any idea how hard they are to use? Price?

I'm still hoping the other bolt will come out, but it's looking like I'll have to drill it out 100% too.

Consider using a heat gun vice a torch to heat up the loctite.

Big Dave

IT'S FIXED.

I ended up drilling out the seized broken bolts and using Heli-Coil. I can finally get moving again on the repair...DR had a fresh order for new parts today from me.

SharkSkin

Nice going, Dave! Remember, anti-seize is your friend...

It's about time....

Baby Jesus (or insert cute mental picture pertaining to your own religion) will smile when you have removed every single bolt on the car and reinstalled it or it's replacement with the appropriate "I'll never have any problems getting that bugger out again" goop)

The definition of a reliable car - if something breaks or fails, all the bolts/nuts/screws/elec connectors undo without drama to allow easy replacement of the failed part.

Careful...the Shrine no longer protects you...

The tally in 6 years is 1 broken motor mount bolt and about 8 broken cam cover bolt spacers. Of course, my engine has historically covered everything in the engine bay with oil anyway.
