Default Stubborn Spark Plug Removal In Progress (HELP!)

Okay, I'm replacing spark plugs on my '99 OBS. I've got both passenger side plugs changed, and the plug closest to the driver (I'm thinking I have plugs for cylinders 1, 3, 4 changed, not sure). Anyways, the last plug is being stubborn.

I am having great difficulting getting the spark plug wire off of the plug. Quick note: I bought the car with 93k miles and has 109k right now... I have no idea when the previous owner (50-ish year old man) did maintenance (no books or records, got the car cheap). The first three plugs look so bad, also...

Any suggestions on getting the plug wire out?

Thanks
-Ben

If it doesn't come off the plug by gently turning it back and forth to break it loose, chances are it may not come off in one piece. The rubber boot could be cooked onto the plug and/or the connector frozen onto the plug terminal from corrosion.
Unless you're willing to take the chance of disabling your car it would be best to get a new set of wires to have on hand first, sounds like you need them anyway.

Thanks

Sometimes pretending the car is not yours will help (that's how most mechanics think anyway). It might be a good idea to use a thin coat of die-electric grease inside the rubber boots to prevent them from sticking to the spark plugs in the future.

Could I tell a Quick Story..

Btw your 99 OBS sounds like a DOHC engine..

When I went to change plugs on my 98 Forester I did not think it would take me 5 Hours to get the friken wire off the Number 3 Cly.. 1 and 2 were easy..

I was pulling all kinds of ways.. I even got onto of the engine and started Pulling upwards on the rubber handle part...

How I finally got the plug loose was getting some Pliers and ripping that sucker off their.. Yea it cost me a new wire set.. but I got it off..

It's a true PITA to change.



Don't they make the DOHC plug wires with a Hard Handle grip for you finger?? That soft rubber junk does nothing for it.

Oh yeah.. I also ended up with 3 Bloody fingers and a Burnt left index finger.

Ow! Mine wasn't that bad in moderation... Just 50 minutes of careful fiddling and 5 minutes of anger-filled full-strength pulls... I guess there is always an optimistic way to look at things... The skin lost from my knuckles will just toughen up my hands more

It's OK to use anti-seize compound on the plug thread, as long as you don't over do it and don't get any on the last couple of threads before the ground electrode. I like to use 10w-30 synthetic oil instead of anti-seize compound. Synthetic oil is less messy, doesn't foul up the plug, and works just as well.

I applied anti-seize very sparingly as it was super messy...

Anyways, yesterday I realized a secondary plug wire problem - The same stubborn plug wire grommet-thingy (the rubber thing connecting the wire to the end of the plug) is not staying on all the time and causing a misfire. Is there no other way to fix this than new wires? I'm really hurting for $45

Thanks

LOL... I'm great at describing this eh? I'm much more of a visual thinker...

It goes
1. Spark Plug
2. Rubber Spark Plug Wire piece that attaches a metal piece to the top of the spark plug. It is also the rubber thing that is visible when looking down at where the spark plug wire enters the cylinder heads... This is the piece that is not staying in all the time... It is a good 3/4-1" out of place.

If this doesn't help, I'll dig up my Chilson and get the name for it...
