Changing spark plugs, bare with me guys....

[mark0101]

hey guys I just started the car up after I did the four spark plugs on the right and it started up fine. As I was doing the other side I remembered that i forgot to put the boot protector, so I am gonna have to open it up again...lol

My plugs looked similar, a little oil on some and completely dry on some. Valve covers don't look fun.

just get a spark plug socket with a magnet ...... do them with the engine COLD, just let it sit overnight, do it first thing in the morning, torque them down to about 18lbs/ft.........NOT inch pounds.......i gap mine to .048........for the boots just look at them see if theyre cracked, theyre rubber.......and put dieelectric grease inside of them (on the spring...) then throw them back on....

oh and if you got oil on the spark plugs, the valve cover gaskets need replacing.......

ive never heard of putting dielectric grease on the inside... anybody else have any input on this?

my 1997 have 150+ I dont know when mine where done im the second owner and im scared i would have the same problem, if so what all would i have to replace to solve this problem?

100k and oil soaked, I would replace them all. Just the boots, not the coils. I'm more concerned about the oil. Oil should not get in there unless the tower seals are shot. Oil will keep getting in if they are. The first three plugs look oil soaked. That can cause some problems with it grounding out resulting i a rough idle and poor economy.

Depending on how much oil was in the tower tube, you may want to consider doing that project as soon as possible. But removing the valve covers is no fun at all.
