Intake manifold brass plug boost leak

Anyone have this issue? Not sure if I can remove the plug and pop in a new one. Thanks

Take the manifold off and have someone weld an aluminum plug in its place. Some cars have blown the plug out under high boost.

Wonder if a little JB Weld would suffice for the short term? You can tell by the dip stick spring that you must be running some high boost. Above 30?

Also, how was that Mani painted (was it powder coated?) I ask only due to the high temps for the PC process

I was thinking the same thing just wanted to confirm with the community first. Thank you very much for the help!

Found this leak due to building up boost and my AFR dropping to low 10’s. I had this car tuned about 2 weeks ago after the motor build at English racing and was running well till about 3 days ago. I’m waiting to pick up my catch can this coming weekend in hopes that I won’t have to run the spring anymore. I painted the manifold with VHT wrinkle black as it had some black paint prior to my ownership. Thanks!
