Intake/Exhaust Manifold Bolt Specs/Replacement
In the process of replacing my cracked exhaust manifold, I've run into a problem that, from what I can tell, is unique only to me.
After disconnecting all the peripherals, I was ready to remove the bolts securing the intake and exhaust manifolds. I had my extensions, universal joints, and PB Blaster, got my gloves on and reached under to see just how inconveniently these bolts were placed, when I discovered that I was exempt from the challenge of having to take them out: all four of the lower intake bolts were missing—presumably from shoddy past service.
While spared from the hassle of having to wrestle those bolts free, my progress is otherwise completely stopped as I’m now facing the more immediate issue of finding replacements for the four missing bolts and their specialized washers.
Any help from anyone with experience in sourcing these parts would be much appreciated. Also, any suggestions on what or where to inspect specifically considering this 200k+ mile vehicle has been driving on an only half-secured intake manifold for an unknown amount of time would also be appreciated.
