How to fix a hair line crack in my intake manifold. You can hardly see it but once it warms up it leeks.
I was changing the heater hose and when I was putting the fitting in the intake it popped and I think I might have cracked it.
You can't fix it. Replace the manifold. If you want to try something, try JB weld, this is a 2 part epoxy.
