Fox egr tube to back of heads is leaking a black goop from it

Never use silicone on a pipe thread
Either teflon tape or the liquid stuff

 

[manicmechanic007]

4 turns is sufficient
And if you have already done it using silicone leave it

I haven't yet I wanted to ask what to use so it didn't leak so thank you again u seem to always answer my post

should I get a high temperature kind of sealant

 

[mattys91gt]

should I get a high temperature kind of sealant

says with PTFE

 

[manicmechanic007]

Teflon is real high temp
You are looking for a thread lubricant as much as a sealer
You don't need a ton of it on there
Liquid is easiest to use and is better looking

was there a way before to block the hole with a penny?

 

[manicmechanic007]

Not sure about that
I worked at the dealer and we used new Ford stuff
Pipes and one way valves
Hell I didn't even know they were threaded
The factory ones just seal with a good machined fit. (like the exhaust manifolds)
The aftermarket Dorman pipes use a gasket I believe

when I first took the pipe off I didn't feel any threads I didn't realize how much carbon was in there it's crazy.what happens now does it just get burned up now?

 

[manicmechanic007]

Well no
It just starts plugging the port once you block it off
You could always bring it back by replacing all the parts and cleaning the ports
That is if you have to pass an I/M test someday
Our state 30 years is an antique and you sign your own inspection
I take it yours is similar?

I'm gonna jump in here, teflon liquid or tape would be useless there, its really hot in that area, like almost exhaust temp hot so you should use something that is for that type of sealant, likely you won't need any if you can turn it in far enough. Spread the sealant on the threads then install in head, let it cure overnight.

I can get 3 to 4 turns in,the passenger side went in further just wanna wait and see what I should use to seal them in I was on my way to the parts store so Incase I have it I'll wait for replays but I have blue lock tight or high temp red rtv or the copper rtv

 

[General karthief]

Something that says 'exhaust '
copper should do the trick

 

[mattys91gt]

I have red or copper rtv

so use the copper rtv or thread lock or a little of both lol I'm jk
