Hello,

94 D I with 98k miles.

I got the car at 87K and changed the plugs. On the right side number 3 plug seemed crossed threaded when I took it out. I put in a bosch plat 2+ and seemed cross threaded when going back in. I put it in while cross threading because it was already threaded that way and I needed a plug in. Today I changed all the others with bosch plat 4+ but that one would not unthread with the same torque I used to put it on. Should I just leave it in and deal with the issue later? What am I looking at in terms of repair?

If it is cross threaded and the threads are all screwed up you will need to tap new threads and use a "heli coil".
You can buy one at NAPA, they will know what you are talking about.

 

Deal with it before it blows out or starts leaking.
Whoever told you to reinstall a plug even though it was cross threaded??
