oil pressure sensor broke in half, made a nice smoke show down the freeway. What should i put on the threads of the new one, silicone, teflon tape, loktite, ???
ARP thread sealant would probably be best, but I used Permatex Blue on mine and no leaks so far. Probably going to be a PITA if I ever need to pull it out though.
I like the ARP idea Matt has. I used a dab of Permatex high temp teflon paste a few threads up on my oil fittings when I installed the Vortech and no leaks with it.
