Hi folks, Tom here, brand new to the Jeep world. Just beginning to dismantle a 51 3a. Allegedly has 23,000 miles but has sat since 1977, in a chicken coop. Planning to get down to frame, toss the body, and build it back up. Todayís question, (the first of many), upon pulling the spark plugs,I can see and flick around with a screwdriver rust flakes.... lots of rust flakes... I imagine now Iím gonna pull the head off for further inspection. Should I be scared and start planning for a new engine or is there hope?
