Default Cross threaded spark plug...

Well the last two days have been quite a journey with my ranger. For starters I have never changed plugs on a ranger, and after learning how buried they were in there I was a little leery. And it would appear with good reason! Since the plugs are at such an odd angle it required the use of some super long extensions (I have big hands and they don't fit any close to the engine!) the plug came out at a funky angle. When the new plug went in I felt it start to thread and then it caught, and jammed. So I guess I gotta learn how to chase threads (not on here lol) or pay someone to do it. I'm sure some of you have run into this problem before as well, so feel free to share your experiences and solutions!

some shops can install a spark plug thread insert (they somewhat bore out the hole then put in a spark plug thread that basically taps itself into the hole and becomes the new thread for the spark plug) but you should only need that for extreme cases

Yeah, I know it's not too bad...I really suck at re-threading things and usually booger 'em up more than they started out. So we'll see what happens!

What size engine do you have? I know the on the 4.0 it's hard to get to the two rear passenger side plugs but you can remove the wheel and well cover to get to them a lot easier. Another suggestion for next time is to always hand tighten them until you can't tighten them anymore OR if you can't reach back there get a rubber tube and attach it to the end of the spark plug. Then just turn the tube to "hand tighten" it in there. You won't be able to get it threaded in as far, but it should hopefully get you started enough so you won't cross thread.

Well I think the old one came out cross threaded...it turned hard all the way out. Come to find out none of the plugs had anti-seize on them. Usually I do just hand tighten, but can't get my fingers in there to do it. So i just stick the socket on and turn it by hand. And it's the 4.0 sohc motor...I'm just going to have my shop re-thread it, since I am terrible at it, and aluminum things really don't like me...

If you're up for it, the parts stores sell the thread chase you need for the plug holes. If you do it, put wheel bearing grease on it to help catch the shavings.

So I took the truck in to the shop today to see if they could find my problem. I had a Ticking noise in the number six cylinder (one closest to the firewall on drivers side) and a rough idle. They pulled the plug to see if any of the head's threading came out with it, and of course, no issues...reinstalled the plug and the thing runs like a champ now. And the other order of business was a vacuum leak that occurs under load in normal driving conditions. I thought it was coming from somewhere in the engine bay but it may be a vacuum line going into the cab...oh boy oh boy this is gonna be a fun one... Any thoughts guys? Best part of my day was when the the guy told me nothing was wrong and only charged me a half hour of labor, which I would gladly pay for peace of mind alone!
