I recently bought an 01 blazer and noticed a coolant leak which led me to replace lower intake manifold gasket. While replacing all the other gaskets broke a rocker arm cover bolt when replacing it. I believe the part number is 10201396. I’ve gotten the old bolt drilled out of the hole but I damaged…

To bad I don’t know anyone with a 2001 Blazer LT with 4.3 vortec two-wheel drive that I could grab a bolt from to take to the auto parts store or hardware store, Maybe you know someone that has a 2001 Blazer LT with 4.3 vortec two-wheel drive you could borrow that bolt from.

This part is a bolt, valve rocker armature cover (1/4-20 x 3 1/2), A heli-coil kit is what to use to repair the threads [image] Tester

That’s the kind of thing where I’d order one at the dealer. Then the thread will be right, and they can tell you the spec for a helicoil kit. And buy a decent torque wrench, and use it.

Order the bolt at a dealership . . . ? Easier to just visit your local pick a part junkyard and get a few of the bolts Almost any 4.3 will have the same bolts, regardless of van, truck, suv

I’ll just say that getting stuck in the mud doesn’t end well. The idea is to avoid getting stuck but most of us have been there. One thing I have been doing for years now and just becomes routine, is when inserting a bolt, rotate it backwards until you feel a click, then go ahead. This insures th…

Awesome that’s just the info I needed. Also, I know that bolt sits between 2 valve springs and is hard to get to. Do you know if the hole that it sits on bottoms out and if it does and I go all the way through do I need to reseal the hole before returning the bolt?
