Installing Sensors

[Doppleganger]

When you fellas install various sensors in the heads or intake, are you using any kind of sealer on the threads? Regardless of a tapered thread, cars I used to work on required just a dab - I used a toothpick with some Permatex on maybe 2 threads, leaving most untouched since they have to ground. Never had a problem - just wunnerin how you guys did it.

depends what its doing. it may ground through a wire narness, it also may through the block like you said. also, it may need to be resistant to higher temps than another spot.. or oil.. or not contaminate something.. etc

I may have used some Teflon tape.

Teflon tape is fine. I use liquid Teflon must faster and it works. Being a line tech time is money.

I’ve been using ARP Teflon paste leftover from my head bolts.

I saw a video of a guy using Loctite 242 on air fittings instead of tape and it worked perfectly. I see they have a 'liquid teflon"....sounds promising.

dont use teflon tape when threading into weaker/less supported threads, because you can break the threads or crunch out that part of the block/head etc.
Its better to use it in liquid form, like permatex high temp thread sealant

Never use Teflon tape on hydraulics or anything else that a piece of it can clog an orifice. Have used anerobic Teflon in a few harder to seal applications. Usually not necessary on anything SB.
