It seems like my spark plugs are welded in I can’t brake them loose I tried soaking them for days and a breaker bar but it feels like if I keep up they are going to strip out ... any help please?

 

Are you using liquid wrench ? maybe an impact wrench set at low torque

 

How many miles and what year is you Crossfire ??
I've heard that the plugs can become almost impossible to remove at or over 100,000 miles

 

The original..... like OEM plugs with nothing but the Benz logo on them are still installed in the 181k mile 3.2 I pulled out of my V8 car.

I pulled a few of them out a few weeks ago and it took quite the effort. Even with the effort, I really didn't expect them to be the factory plugs because the engine ran so good.

I would really twist on them, but your car is not my car.

Good luck.

In our houseboats we would run MMO in the fuel a week ahead of time and then again spray each plug the night before doing the plug change. it worked.

 

2005 and 138k I have had the car sence 2010 and never changed the plugs

 

run the car to warm up the motor, then shut it off and try again

 

Also hitting it with a impact worked on a car I had, if you can use one that is. the car i used it on was a 2.2 inline four so the plugs were easy to get to.

 

Well I have tried heating up the engine and lightly hitting them and tighten and losses... they are stuck in there can’t even get one out ....Dammm!!!

 

It may help to remove the valve covers to give you better access?

 

Yea that’s what I was thinking also 👍

 

Yes, it is well worth the effort to remove the valve covers when doing plugs.

 

soak'em with plenty penetrating oil, tighten first n then loosen, patience is the key and soak the s-it out of em

 

Thank you all for the help !!! Well it’s been a battle and doing everything I could do working on and off for over a month and I have gotten 8 out so far sooo I’m breaking down and it’s going to the shop !!!

 

well the dealer I took it to told me I need new heads put in …. I went to a few other shops but no luck no one wants to touch it till I find German auto repair in Placerville California they had the car for 6 weeks but they did do it changed all plugs and now my SRT -6 is running great and it only took a little over 6 months…..LOL

 

So now we should call you fasterfred?👍

 

funny but yea it runs so much better with the factory plugs gone they where in there from 2005 till 2021 and 139 k miles on them …LOL

 

They probably had gaps you could drive a bus through, definitely time for a change.
I should loosen mine and retighten them, I do not want them to seize up in place.
