That's a really great idea that I hadn't thought of. I will take a closer look tonight to see how feasible it would be.

If I move one way or the other, it might be outside of the casting area that houses the bolt holes, and potentially end up entering the coolant cavity; but, I'm going to light a candle to the DIY gods, and hopefully this will be a viable option.

There's no room to move the holes. *sad-trombone*

I was able to get a masonry drill bit that's been making some slow progress. Took about 5 hours to get through 1/2 inch of the carbide tap, but any progress at this point makes my innards smile.

This experience has made me conclude that things made of carbide are actually made of dark magic, and the souls of cursed bunions.

Yep, that bolt is not in the block - it is in the intake. You can get a used intake manual for around $50 from a wrecking yard, or used aftermarket alloy intakes for SBCs are around $75. Changing the intake it not too onerous. Pull the differential, carb, egr stuff (if you have such) and swap. You will need a gasket kit.

If you are able to drill it out, that is good too - but 5 hrs? Whoof. IF you damage the threads, chase them with a tap. If you destroy the threads, helicoil.

Thank you SteelHead. I was thinking of trying to tackle a TBI rebuild, so now knowing that it's the intake manifold (and the price), I might go that route instead since I'd already likely be removing the TBI anyway.

This truck has been the first time I've done anything more than an oil change all on my lonesome, so there's been some interesting learning experiences (this probably being the, ummm... most 'giving' of those experiences).

This little thermostat housing snafu has occupied more time than the fuel filter, master cylinder, brake booster, indicator lights, and heater bypass combined.


(TMI aside to follow)

Each winter, to get me through the ole seasonal depression, I take on a hobby. Last year was building computers, the year before than was woodworking, before than was aquariums, and on and on. This year, I took on this truck. It has certainly kept my brain occupied, but it’s kind of an abusive relationship.

Broken bolts are always a pita and take more time than they should.

I was fixing an inner axle seal on my Isuzu Axiom a few years back and to do so I needed to pull the spindle nut. Seems like a simple enough job right? I broke two 2 foot breaker bars jumping on them trying to get that nut loose. Ended up having to drill into the nut 3 spots in a line and crack it open with a cold chisel. What should have been 2 minutes of work to remove a nut, took 6 hours.

When I first broke the tap off in there, I texted my dad for advice. He replied “Drill with one hand; read a good novel with the other.”
