Hey,
I was replacing the lower and upper intake manifold gaskets on my 98 4.0 SOHC. 50000 miles with the check engine light but I finally decided to tackle it.
Sadly, when double checking the final torque on the lower intake bolts (I'm doing 150 inch pounds) I ended up threading one of them. It started spinning and offers very little resistance now. Took it out - the bolt looks OK so I think I must have stripped the bore itself.
I've red circled the one that it is in the attached picture.
If all the other bolts are snug to spec, how bad is this? Will it start leaking straight away or should it be ok with the pressure from the surrounding bolts?
I cleaned the heads and everything else very well so the gaskets should have a solid mating surface.
Is there some kind of product I can put on the bolt that could help??
ARG!
