I know what teflon and lock-tite are for. What I want to know is where are they used most often. I know teflon should be used for oil/water lines, but what I was wondering was about the heat from turbo. Is this enough to melt or deteriate the teflon. And what bolts should you use lock-tite on. Just something that I have been thinking about here before my turbo project. Thanks for any info.
