cracked intake
on my 428, the intake is cracked on the top waterneck mounting stud boss.
this was noticed when i was trying to stop all the leaks. i need to make a temporary repair that will last till i pull the motor for the restoration next year.
i am thinking of pulling the waterneck, setting the stud in place, and using JB weld to hold it in place and seal the crack. what do yall think???
btw, this is on an edelbrock F427 aluminum intake.

Yeah JB weld or Epoxy that head porters use, is about the only quick fix I can think of.
And then when ya get the time..drill it out and retap it over size and put King serts in it..and it will hold til the cows come home!! LOL

Yup Epoxy is probably the best bet.
I use a thing called Marine-Tex, a very hard epoxy that people have used to seal cracked blocks/heads/manifolds in boats for the last 20 years.
Sounds like it's the same thing as JB Weld.
Just make sure you mix it right, and make sure the surfaces are clean as a whistle.

I oiled the block down, spread marine-tex on the inside of the sheet metal form, bolted it up to the block, let the marine-tex cure 24 hours, removed the form, cleaned the block, spread RTV on the marine-tex mold, and bolted it back onto the block. No more leak ... for 10 years... held 14 lbs pressure too...
