The engine is still in the car at present

The manifold is aluminum and the studs are steel, so I'm pretty certain there's been a reaction between the two metals. I have been spraying with penetrating oil and carefully tapping the studs sideways with mallet and wood block x2 daily for the last week or so.
Expert:  Matt replied 1 year ago.


if the manifold is jammed onto its studs then yes its possible its down to corrosion

what may help is if you try removing the studs from the cylinder head to wind them out with a pair of locked up nuts

also the latest freeze sprays are good at releasing parts
