Just as I was fitting flywheel to my EA82T I noticed a little welch plug of about 10mm in the rear of the inlet manifold on the bolt on bit at the back easily visible from the flywheel view.
It was turning a rusty brown as in rust through sort of thing.
I have jammed it ull of epoxy until further notice.
Just thought it worth an alert to check it with a mirror on you EA82T's and mpfi to save grief at a later date. What is worse is there is two plugs in same spot one is a little bigger. I think there are a few more of these welch plugs on these manifolds. Well worth checking me thinks
