PITA

[tmf6902]

Well after reading everything everybody had to say about the 100k mile spark plugs I decided to change mine out. What a PITA, the d**n plugs boots were harder than hell to get off the plugs.....I saw someone used a flat head screw driver to sort of pry them off and that worked to loosen them up.....getting the plugs them self off was eay except for the 2 closest to the firewall on the driver side, the steering column sorta gets in the way, and my hands aren't exactly the smallest in the world, but I got them out finally.....the one closest to the firewall on the driver side I found was easiest to get from underneat the truck. But I got some dielectric lube for the boots so everything should go much better next time, plus I know all the tricks now.....the one thing I do have a question about is, what's up with the spring in the metal heat shield on the boots.....I can't figure that one out, it certainly didn't make the wire removal any easier.....

 

oh yeah, the plugs where shot too.....really coroded(sp?) and fouled, I was kinda suprised since I only have 30k on it, I couldn't imagine what they would have looked like with 100k on it. I'll have to see if my mpg is affected, but the engine did seem a little more spy after I swapped them out. Just for reference I put autolite normal copper plugsin there, we'll see how they last?

yeah I make fun but a 94 corisica is the worst, I am pretty sure you have to take out the entire engine to swap out plugs and wires.....dunno, my womans car, and she always pays someone to do it, you can't see three of the wires and plugs so I am not even sure they're there.

I thought the plug swap on my 8.1 was a cakewalk.I just grabbed the metal sleeve on the plugwire twisted it back and forth and they popped off easily.A short extension and a swivel made quick work of the plugs.Total time spent was a 1/2 hr max.Did'nt have bloody knuckles either.

LS1's are a piece of cake, I've got mine down to about 30 minutes. You haven't had fun until you've had to remove the upper intake plenums and then "rotate" the engine in some FWD GM V6 cars.

 

It's all in having the right tools. May I suggest to those who have problems to invest in swivel based spark plug sockets, palm and stubby ratchets. Go to Snap-On.com and check em out. Mine are all beat to hell cause I use them soo much.

 

BTW, it took me about 15 minutes without nary a problem on my truck.

Yeah I dont know how the hell they do it with the corisica, which is a FWD v6, you can't even see the wires for 3 of the cylnders, their between the firewall and the block somewhere...my hands are to big to get in there....they probably just take the engine out or something..

I had to remove the front 'dog bone' on my 1987 Olds Ciera GT 3.8 V6. Those rear three plugs were still a real Bit(h to do

 

My 5.3 GMC wasn't bad at all, the only one that put up any type of a fight was the rear passenger side plug. Pretty simple otherwise

What Joe said. GM calls it "rotating" the motor. You remove the upper motor mount which is commonly referred to as "the dogbone", hook a come-a-long to the upper motor hoist ring, hook the other end to a suitable and stable location (wall, big tree stump, another vehicle, etc) and ratchet the engine forward.

 

From there it's a piece of cake.

 

My Mother thought it was hilarious when I was replacing an O2 sensor on her Monte so she got a picture of it somewhere where I used our dead willow tree stump to "rotate" the engine. I'll have to find it.
