I'm in the process of piecing back together a jigsaw puzzle (304 VR). Purchased in pieces. I'm about to put the intake manifold back on....

 

Prior to cleaning it up - I observed silicone around the base of this pipe - can only assume there may have been a leak. No info or history from previous owner.

 

Is this a common issue?

 

Thinking of using some kind of sealant on this prior to installing. Thought about araldite, but read it might not cope well with high temps. What about JB Weld? Keen to hear your thoughts....

I reckon go the jb weld, just the original type
It can handle a fair bit of heat
Should easily survive life on the outside of your manifold
Lots of guys use it as filler inside manifolds

If you are worried about it now would be the time to remove it, tap the hole and put a nipple in. Sort of like a HT-HG 253/308:

You can put all the sealer in the world around that outlet, but it's only a bandaid fix, as yel327 has said, remove it, tap the hole & screw a fitting in it.

Use a brass fitting. Should reduce the future corrosion risk over the steel one that’s in there.
