PSA: That cheap injector puller from Harbor Freight cost me a full day of labor
Snapped the threads off on a 6.0 Powerstroke at 10 AM last Tuesday and spent until 5 PM drilling out the broken piece what did that save me really? Anybody else learn this lesson the hard way?

Stay away from those cheap pullers especially on 6.0s. I had the same thing happen on a 7.3 a few years back and it took me two days to fix because the hardened steel just snapped off deep in the hole. What nobody talks about is how the cheap steel actually work-hardens when you put torque on it and then it becomes this brittle glass-like chunk that shatters instead of gripping. I found out the hard way that the real cost isn't the tool or the time it's the risk of damaging the injector bore itself. If you nick that bore you're looking at a whole new head or a very expensive repair. Now I only use the OTC puller with the collet style grip and I still take it slow with penetrating oil first.

Funny you mention that @lindahunt, I've had better luck heating the area just a little first.

Wait, you're telling me the cheap steel actually gets harder and more brittle under torque? Cause I used to be one of those guys who thought "a puller is a puller, how bad could the cheap one be?" But after reading this I'm rethinking that whole mindset. I had a similar scare on a 6.0 last year where the cheap puller started to twist before it even grabbed the injector and I was this close to snapping it off. Looking back, I got lucky and that scares me a bit. It's the kind of lesson you don't want to learn the hard way like you did.
