Default Spark Plug.........fail

Just found the plug in my garage. Here is the story. 2yrs ago, before my engine rebuild my brother-in-law the mechanic "helped" me change the injectors and do a tuneup. Some of the plastic tips came off the old injectors and I couldn't fish them out of the intake manifold. I cranked the engine over for a few seconds with the plugs off and nothing came out of the plug holes.

We then re-assembled everything, putting in the plugs last. My brother-in-law had a hard time getting in the plug on #4 but got it threaded and connected. Upon startup the engine was missing badly. Pulled the injector connectors off one at a time and sure enough when we pulled #4 injector there was no change in the way the engine was running. Here is what we found:

Dont worry he lives in an out of the way place and said wont touch another Vette and he is retired. Yes after that I'm doing all the wrenching myself.

I have a GM mechanic living across the street from me. He likes to give advice. Sometimes he knows a good trick to get something done and other times he scares me. I asked him if he knew the torque specs of something off the top of his head and he just said gudentite. I was torquing down tie-rod end castle nuts. I went and looked it up in the book.

Around these here parts we torque 'em real good. It's called a "Hillbilly Locknut". Tighten it up until you strip the threads and back it off half a turn. Works for me.

Good Gosh, I'll take the German torque spec "Gudentite" over that.

Yeah, there's the old saw: "What do you call the person in medical school that graduated at the bottom of the class?" (Answer): Doctor!

So it goes with most professions, I guess. I've run across a few real "**** fists" mechanics in my travels - many working for dealers, too! (And, I think most of them worked on my wife's 69 C3 at one time or another!! Never saw so much cobbled up stuff in my life - and most evident when it involves electrical repairs or modifications!) (Don't get me started!!)
