That permatex you used is great on flat surfaces, flanges, exhaust *****, probably the best. For threads, it's useless. I've tried it in my youth with air lines..most likley thinking the same as you were.

You'll skin this cat, one way or the other.

Yeah, if you used the Permatex Ultra Copper, that's more of an exhaust gasket sealer. I've never seen it used to retain liquid.

i guess i didnt think teflon tape would hold up to the heat. i have some of the yellow stuff for gas lines, i used it on all of the fittings for the air ride on my s10

This is a handy tool.

Good luck with it, hope it works. Only reason it wouldn't is because your not dealing with a tapered thread chamber. It's a straight thread chamber. It's worth a shot though.

Yeah, it may not work. I briefly poked around on some Chrysler forums and most of them are using various types of RTV. I did see some PTFE tape mentioned though. Hell, it might be just fine putting PTFE tape on a regular length bolt and using that. In fact, that just might be even better. I know that the teflon tape most definitely works at holding header bolts in.

thanks guys, looks like ill be off to the parts store to rent the pressure tester again. If the yellow gas tape doesent work, im pretty sure i have a roll of the white industrial in my toolbox at work to try. At least i wont have to wait 24hrs like with the rtv

I'm really curious now, so please let us know what works for you.

I don't know about gas tape for fluid, it's for low pressure gas, but it might work.
If you want to better PTFE tape. You would jump up to Loctite 567. If you use it w/Loctite 7471 Primer it'll cure quicker.

That's what I use, NEVER had a leak.
