Vent Cap Stuck

Murfee

Due to moving, my EGG has been in storage for appx. 4 months.  Now that it has a new home, I've started refurbishing all the metal components.  She's 13 years old and the last 7 years have been in salt air so the nest and hinge assembly were pretty nasty.  Sandblasting and powder coating work wonders.  My problem is that the daisy wheel vent cap is stuck to the ceramic dome.  I believe it is due to the creosote build up inside the cap.   Any advice on separating the two without causing any damage?


In advance, thanks

Heat. 

Will it open?

+1 Fire it up and warm that thing up.  Prop the lid open a little for airflow if necessary while allowing the dome to still get hot.

The metal cap will expand at a faster rate than the ceramic.  Grab some hi temp gloves or pot holders to wiggle that thing off.

Oh and you might as well cook something in the process!  😁

Exactly what was said above. I’m guessing by about 400 to 500 that thing will start to loosen up. But also, welcome to the forum.

Oh yes welcome!  Didn't see the post count!

Welcome. Crank it up and lift off the cap with gloves or hot pads.

Nothing to add to the above suggestions.

However, welcome aboard and continue to enjoy the journey.  Way to step out of the shadows.  With 13 years of experience I'm sure there are many things you can offer around here.
