It has been in storage with out any after run oil for 13 years, a glow plug is not going to work in this case. I started soaking it in clean fuel then soaked it in sea foam. it is real stiff and gummed up, going to try the crock pot filled with undiluted anti freeze this weekend on low. I will let you know how it comes out,
I seen at Walmart a 2QT pot for 7.99 New. A gallon of old green is 13.00 so we will see how this comes out.
