Hey all.
This is a manifold I removed from a 4.0 efi Ford
v-6.
The unit was blowing steam from the head gasket (I
thought) and I tore it down to change the head
gaskets and I found this problem with the lower
intake manifold.
The pitted area is on a mating surface for the
water jacket and looks like either a casting flaw
or corrosion.
My query is should I just use some RTV on the area
and call it good or should I try to get another
manifold?.
I could probably weld it successfully but it is a
precision fit between the heads and I have no way
of machining it correctly.
BTW this is a '97 explorer used mostly as a parts
chaser.
Thanks in advance,
Brad
