I started the project this evening when I got home from work. Went through and broke the plugs loose and gave them an eight to quarter turn each while the engine was hot. Then I put some CLP in each hole and went back through and just attempted to turn each plug back and forth 2-3 times to work the oil in. I'm concerned though. Plug #6 was loose enough I was able to spin out mostly by hand. The rest are very very tight. Are galled threads on these engines a big issue? For those that have done the plug change, is this typical? Do they loosen up a lot when the engine cools?

 

Problem is not the treads....I hope you have the Lisle Extraction Tool?

 

Not really. Sounds like it broke. Did the entire plug come out, or just the threaded shoulder? Threads shouldn't be a problem for you. Hopefully, they were installed with anti seize compound.

 

With aluminum heads, I have always heard that the engine needs to be cold before taking out the plugs. Otherwise the threads could be damaged. Also, since it is an 08, there is a very low chance you have the two piece plugs that break. If the coil boots were brown they are one piece plugs and should come out without an issue.

 

it's an 08 they changed the plugs in like 07 I think

I did the plugs on my 08 awhile back it's really not bad.

With it being an aluminum head do it COLD, spay a bit of lube on each one let it soak. When you unscrew them use a short handled ratchet and work the plug back and forth until it backs off easy, you never want to put allot of force on aluminum.

the back two cylinders take a bit of finesse I found myself using a swivel and basically sitting on the rad support.

When it comes time to put the new ones in vacuum out each hole and make sure you use some antiseize on the threads and a little dielectric grease on the top of the plug never hurt either
