Probably so, but just to be safe use thread sealer so you don't have to worry about it.

Jeff,

Read the instructions on a tube of rtv. I really do not think it is designed to seal threaded connections. Use a good teflon based thread sealer.

Just my opinion,

The rtv can ease its way out over time with heat stress pressure. I would use liquid teflon or teflon tape.

I would NOT use RTV on pipe plugs. Use a good thread sealer.

I've been using RTV on pipe plugs and freeze plugs since it first came out, what's supposed to be wrong with it? I don't think there's any oil or water pressure in an automotive engine that can push cured RTV out of tapered pipe threads. I don't think 10 (ten) times the pressures seen in our engines would hurt that stuff.

ok guys, i got some good thread sealer. now, how do i know how tight to get them? do i need to make them flush with the block? im using a rachet with an allen head socket, so i have enough leverage.

thanks guys

Do not over tighten you will crack something

 

[jks67SS396]

so there is not a "depth" that i need to go to... just get it tight and its good?

thanks

Yeah, pipe plugs use tapered threads. I just use teflon tape. Make sure to wrap it in the right direction, if you don't, it will just unwind itself when you thread it together. Then, after it's together, I peel all visible tape back off, makes for a very nice and clean setup!

Go to a local plumbing supply store and get a small can of Rectoseal #5.
