Couple random questions for the group.

I'm looking for the proper thread lube to reinstall the sensor on the head that is made of plastic (It's on the left side and has the twin tubes off it). So, it will be aluminum to plastic threads. I know some/most antisieze and thread lubes containing petroleum, which will attack plastic - anyone know of one designed for plastic or another substance I might use? This sensor was not screwed all the way in from the factory so when I reinstall I am going to want a lube to properly reseat it. I have O ring lube around, as well as dielectric grease - both of which are for rubber but I don't know if the heat of the head will turn these into something nasty.

Also, has anyone had luck simply removing and cleaning an oxygen sensor? Other sensors of this type I'm familiar with simply get a layer of crud on them that inhibits their highly sensitive sensing. While the truck's sitting I thought I might clean them if anyone else has done it and successfully rejuvinated theirs after throwing a code (I have no current issues).

Has anyone ever pulled their front door key tumblers for cleaning? Mine are getting grundgy and liquid graphite isn't helping anymore.

I'd use some teflon paste on that plastic sensor. This is quite common in the plumbing industry.

Hey doug are you sure it is plastic, Just about every one of the Vaccuum sensor that operate on coolant temp are brass then plastic. Hs yours just gotten black with age? then I would use the teflon paste either way. later robbie

Probably a build up of graphite .

cleaning the oxy sensor

I've read somewhere that you can burn off the crud using a "de-tuned" oxy-acetylene torch. get it red hot and that burns off the crud. never tried it myself, so ymmv!

Certainly seems worth a try.

i broke my drives door handle a while back. they are easy to remove. just pull the inner door panel and you can see every thing that holds the door handle in. you can pull the handle with the lock in it or just the lock. i think it is a 10mm head bolt that holds it in.
