Quality control??

Guessing this plug is a leak filler in this 906 head that I've had since the 70's but I'm not gonna' remove it to find out.....

Yup. It’s not leaking so I wouldn’t even look at it knowing my luck.

It would think I was side eyeing it and it would start leaking just to irritate me.

I’m not poking that bear.

That is a clever repair.

The top picture is a pin hole that opened up when I charged the cooling system.

Brand new intake manifold.

The bottom picture is my fix.

I was going to pull the intake and run it up on the hill so @MOPARMAGA could TIG it.

Then I said screw that and fixed it with a plug.

Just crap **** any more. It cost me at least two hours to unscrew that.

Holley can suck it.

Did you go all of the way through with the drill?

Is there a reason you're keeping the intake make and model a secret?

The manifold is a brand new Weiand tunnel ram. It was from the last batch that Holley made and supposedly they won’t make any more.

And, Holley says they used the exact molds that Weiand did years ago. I’m not sure I buy that now. But I did when I got it.

I don’t know how many manifolds of every brand I can think that I installed and never saw this before.

It’s like @Oldmanmopar said above. His kid is pressure testing everything.

That’s where I’m at. Another detail that must be verified.

If this was a customer engine on the dyno I’d be losing my entire *** and probably both legs on this time burglar.

Edit: if Speedmaster made a tunnel ram I’d look at it.

Nevermind. I missed this post.

This is why I ALWAYS recommend going with vintage stuff. It's always better. The aftermarket always finds ways to make things cheaper. That usually means thinner. It flat out sucks dead rotten elephant balls that it was new.

Yup.

It’s not very thick there either.

 

[Bodyperson]

Yup.

It’s not very thick there either.

Luckily it was close to the thermostat housing making cleaning the chips easier.

 

[RustyRatRod]

Yup.

It’s not very thick there either.

Thick enough for some threads, thankfully.

Oh wait, after looking at the pics you did not remove the thermostat. I'm sure there is some technique to successively pull that off. I would have to pull the thermostat.

Weiand.

I’m still trying to get my head around what it would be like finding a gravity powered water leak on an out of the box probably $600 plus intake…

I would keep a close eye on the spot and repair. More often than not in my experience, the cavity can go other places as well after more heat cycles. Hopefully no coolant makes it to an intake port

Back in the '80's, I worked for a Buddy's Dad, and at some point He purchased a diesel Lynx. Couple of years later, that thing was leaking oil around a head bolt up front, so He pulled the head & brought it to Me. The oil gallery running across the frt. was leaking thru' the casting right to the head bolt hole, so I yanked the plug, sized it & pressed a tube w/sleeve retainer on it into the gallery...pretty long ways there. It lasted for a few months, then sprung somewhere else.....they said screw it & just kept adding oil, lol.......

Let alone the hours he has into the plenum modifications...
