Guys, the worst imaginable disaster for me happened last night while doing this procedure. I overtightened the oil pump T45 torx bolt until it snapped
. I don't know what became of me (I guess because I was working late into the night), but I kept turning the torque wrench because it wasn't clicking, I suspect the bolt was stretching. I've been wrenching for years as a hobby and I should have known better. I feel terrible. May be I jinxed myself by asking about that bolt in the previous thread
.
I've found a great video on techniques of extracting a broken bolt without damaging the thread. But now I'm wondering, other than not being able to retighten the chain in the future, the pump will still work fine because the remaining piece is holding things up? What are the risks of leaving things as is? I can tackle the extraction later.
