I have a 85 cherokee 4 banger and the same thing happened I pulled
the #2 and it was broken & bent at the electrode,
I thought great pieces in the cylinder chamber tried fishing out and
nothing came out I even removed the oil pan and checked for metal
still nothing put all back togather w/ new plug and did a compression check on all cylinders and had #1 150p.s.i #2 130 p.s.i #3 150 p.s.i
#4 150 p.s.i then started motor and sounds like I have a sticky lifter
but still runs half way decent.
I dont know what to do next, Thinking about doing engine swap
to a chevy v6 f.i. any help would be great
