Thank you to everyone on the BC who insisted I do the lower gaskets when changing
my upper plenum.
I finished the job today.
Here is what I found:
*Lower gaskets were literally falling apart.
*Oil ponding in the left rear and right front of lower.
*Upper gasket flattened on throttle body and leaking.
*Egr tube stuck and burnt to upper plenum.
The hardest part was cleaning everything and getting the fuel rail out.
It would only budge after I soaked the injector bodies with oil then continued rocking it.
Coolant elbow was a little tricky.
I will be updating this post with pics shortly.
I concluded the job with an oil and filter change and she'* ready to go.
To everyone out there that is thinking of changing their gaskets and plenum as a preventative measure "Do it". You won't be sorry you did.
I'd rather pay a little now than a lot later.
