Hi all,
I needed a new apps so I got a new duralst apps and installed it as per the directions. Got it set to .563v. So far everything seems great! I do have one question though. Would you guys use loctite on those screws? I know they have it from the factory, and the new ones that came with the sensor had the dry blue stuff on them. Well me and my ocd personality couldn't remember if I tightened the one screw all the way or not and I was worried about it vibrating loose. So I pulled the thing back apart today and of course it was tight but I re adjusted the sensor and then tightened the screws again this time making a mental note of it. Then I added some of the green light duty loctite that you can put on after assembly since loosening the screws messed up the blue stuff that they came with. Do you all think that's good enough? Or should I pull it apart again all the way and put regular blue loctite on the screws before installing them?

Thanks in advance!

 

The green stuff should suffice. Make note of how it looks now and take a look during your oil changes and any other time you have the hood open. If you ever see it move, then you'll know to use the blue stuff.

FWIW I don't think my apps has any, unless they used it at the factory. 15 years old and still going on the original (knockin on wood).

 

You can use a paint pen and put a small mark on the screw and another directly beside it on the mounting surface to see if it is backing out or not....
