Hey all.
Just acquired a 98 Dak V6, 3.9L. Getting lousy gas mileage, so replaced O2 sensor. That got me up to 13.6 mpg. NEXT: went to replace plugs, wires, distrib cap & rotor. mpg pending.
Found the "Heat Shields" to be a royal PITA. Especially the one next to the vacuum booster (left rearmost).
Any suggestions how to remove the shields? Are they necessary?
Thanks.
James

 

remove them, they are useless. i removed mine, plug boots havent melted, so its good.soak em in pb blaster. get some vise grips, crimp the shield together, and get angry at it.

 

lol I can get angry, its kinda what I do

So they are just set in there? Are they that annoying?

 

yeah theyre pressed in, they make it a pita to remove the spark plugs, without those shield i was able to shave off about 15 mins doing a spark plug job

 

well Ill keep that in mind when I do my plugs

Will the PB blaster effect anything. Do you spray the sleeves with the old plugs in? I like to ask the stupid questions, can you tell

 

you can as long as youre gonna replace the wires, otherwise remove them, but label what cylinder they go to

 

ya keep the plugs in until you those shields off. Otherwise you will get debris in the cylinder.
