Coolant in spark plug valley :(

[mytmk3]

Looking for ideas here realy hope it's not a worst case thing here

There's no coolant splatter under the hood so there's no where else from it to come from other than the head between 3-4 cylinders

Here's the photo


Motor was rebuilt done 8+ hours dyno time and maybe 500kms on the road

the large hex plug in the bottom of the spark plug valley seals the coolant passages. the only thing I can think of is that it's leaking, and those should not have been touched when the motor was rebuilt

They're also a BITCH to get out... http://www.cygnusx1.net/Supra/TechTips/head_coolant_leak.aspx

That looks like fun is the world going to implode if I ignore it for a little bit to make the drags this weekend? It doesn't exatly leak in a hurry

I made my own tool to remove these, found a bolt the fit and welded a nut to it.

I wouldn't.
Leaks can always get worse.
It's an hour job, maybe 2 to make up a custom tool to break them loose.
Drain your system, pull the plugs, clean and reseal them.
Job done.
An over heated 7M tkes a bunch more to fix.

Yup, did the same here.
You could also find some hex stock, or a long nut that you could then put a socket on.
