Broken guide bolt
Hi,
I have a 2006 HHR 2.4L engine that I discovered had a bolt that was sheared off by a broken timing chain.
Got the installation almost done when I discovered the broken bolt. Trying to figure out what to do to either fix or remove what is left in the block in order to install the new bolt.
I have a screw extractor set but I can't drill out the old bolt enough to make it catch. I thought about just completely drilling out the hole and using JB Weld to rebuild the hole but I'm not sure that will hold on a hot engine soaked with oil.
Any one with an idea would be appreciated.

I suggest, find the centre of the broken bolt, use an 1/8” drill bit , Dewalt has a package of two , drill into the bolt 1/2” use an easy out to extract the bolt.
you might find it easier to access with the drill if you lower the engine on a floor jack and a block of wood under the oil pan.
I haven’t seen the bottom bolt break off in a while, the intake balance shaft bolt head is pretty beaten up too.
