Attempting to do the breather mod on this engine. Since the PIB mentions the blower cover and the intake manifold, after looking things over
got the blower shroud moved over far enough to scope things out.
I can see one bolt of the cover and it is finger loose. I decided, rather than take out the firewall/bulkhead, to just remove the intake manifold, thinking that would save a lot of work and time. I do have gaskets on hand.
But, after removing the 2 bolts per side on the intake manifold, it does not want to move. From what I can see those are the only things holding it on and the engine breakdown diagram does not suggest otherwise.
Thinking it must be only gasket seal holding it, but I am very hesitant to try force without checking with experts.
Decided to do this today as next few days may bring severe weather my way.
