Changing spark plugs

[vortecd]

I changed mine about a month ago and this is what I found. I started with the passenger side. Unbolt the intercooler reservoir and roll it towards the engine so you can get in there. One of the biggest issues is disconnecting the plugs. @16GoManGoHC2 posted a tool to help but I didn't have it. I was able to get the first 2 unplugged but even after pulling the 3rd coil pack out I still couldn't get it off but didn't need to. I also couldn't pull number 3 and 4 coils out. @jonx96 had already did his and said push them to the side being the boots are flexible. That side fighting everything took a few hours. After doing it I could cut that down in half. I wouldn't even try to take the plug off of 3 and 4.
The driver side took about an hour. I did take the airbox out and took the bolts out of the coolant reservoir so I could move it. The plugs on this side are facing you so much easier to unplug them

The 5.7 and 392 don't have the hump in the valve covers and the coil packs are spun around with the plugs on top so they are much easier to change

@white1 posted this socket to help which I did buy. Worked pretty good

Thanks for tips as well as others. I'm not looking forward to doing this, back hurts thinking about it. I'm at 11k so might not worry until 20k ??

Like a lot of things once you do it not as big of a deal the next time. It's that 1st time not knowing what you have to do. I know I can do it way faster the next time

Stock power, no engine mods…how long can I go without having to be concerned with this ball aching bad time?

Follow service manual recommendations, at least 50k I would think?

I haven’t given up, still looking on how to get some of the material.

As the spark plug master I'm going to show you what sockets/adapters I use, just woke up and saw this thread...


the ratchets literally paid for themselves in full for this job, got them yesterday.

Also cut that fucking plastic box out and wrap the wires in a nice tape and shield, it exists for zero reasons.

To which of the useless boxes do you specifically refer to?

I had no issue with that other then preventing me from pulling the coil out which I didn't need to do

I used a standard 3/8 ratchet, the swivel spark plug socket white1 suggested and different length extension possibly wobble ones on occasion

So Jon and I learned if the plugs threads are shiny you don't need to use anti-seize since they are already coated. The autolites I used years ago were black and for those you do

Be careful with the coil pack boots. They can crack when bent too far and you get misfires.

I was wondering what happened to the heat shield?

Like the rest of Covid, material shortage from supplier

This one, attached to side of strut tower passenger side.

Wrap wires in this instead, from McmasterCarr
