Lower timing belt cover bolt snapped off inside block...too small for EZ Out?

[TJTJ]

I was doing a timing belt change, closing it up, and on the last bolt for the lower cover, the one up and to the left of the central one under the crank.

It snapped for some reason (low torque, with rubber washer, etc...), and, the SHAFT snapped, so the bolt remaining is deep inside the hole...nothing close to sticking out.

I tried to drill and get an EZ Out into it, but, its too far in. (I think its that Looong bolt with the short threaded part at its end...)

First time I've lost one like that...any tricks anyone has for that sort of extraction?

:sure:



Plan B - Caulk the cover to close the gap and hope for the best?

hmmm

Shoulda looked closer.

Its not the long bolt that snapped, I got the wrong replacement bolt.

I can get behind the bolt, in the block, it seems after using a mirror to see where it fit into.

Whew.

Not sure if you’re still needing to extract a broken bolt or not but I have had great success with THIS from SnapOn.

I believe Ridged and Irwin make a similar set but I have the Snapon one and it hasn’t let me down yet.

Good luck…

Yeah, I need that...the bugger is still jammed in there.

I also need a new bolt, and, the dealer sent me the wrong one (Again)

What has made this work for me is the drill guide. It keeps the drill bit from dancing, centering it. Cutting oil or PB blaster while you drill through the broken bolt. Tap the extractor in, slip the hex nut over it, socket and gently work it loose then out. I haven't used it with cover bolt but have had success with many wheel studs and with an oil pan bolt.
Good luck...

Yeah, its down in the hole, no slipping of hex nuts over anything.



It needs to be drilled out...and the cutting oil, etc, is how. If I can get the drill bit to make more than a dimple, as in enough of a hole so that I can thread an extractor into it...I'll be golden....especially if said extractor is not so fat that it strips out the HOLE's threads

So far, the broken off bolt section, deep inside the threaded bolt hole, seems to be poor at not snapping, but GREAT at dulling drill bits.

Just updating that I had eventually drilled into it enough, and did extract the mofo.



It took ~ 5 trips to the dealer to get a new bolt/rubber washer...as they kept giving me the wrong parts....as it turns out, because the FSM drawing is wrong.

The bottom outer left bolt for the lower timing belt cover is SHOWN as the top inner left bolt position.
