98 4.0 sohc spark plug stripped

[Foxhound_22]

I got all but one plug out, the one stuck is the back passenger, I think I stripped the head of it seems like I need a really thin walled socket to get the socket on the head properly, can't really get a good look cause of the crappy position an advice?

IIRC, the metal spark plug "sleeves" pull right out. Preferred tool for plug removal is a 14mm SIX point deep socket.

Pulling the plastic fender liner is the only thing I can think of right now, to get access.

Good point. In addition, an empty wheel well without the passenger tire makes #3 very easy to reach straight.

Well finally got the last plug, removed all of the fender plastic stuff then use one of those sockets that fit any bolt with the weird teeth and let the pb blaster do its thing an it came off

What shapes are the plugs in? I am afraid to go through all the trouble, and perhaps break something, then find out I really didn’t have to change them.

They were definitely old an needed to be replaced, someone put auto lites in so stuck Motorcraft back In

I have been burned too many times for messing with something that wasn’t broken (not that I don’t get tempted). My truck has running issues but doubt they are plug related.

Ya that's the toughest plug to get I had trouble . what I used was I put the spark plug socket on the plug and used a stubby wrench to fit in there. A quarter of a turn at a time took me for ever!!
