I just changed my plugs myself at 200,000 miles and had no problem with them coming apart in the block because I put 2 cans of Seafoam through my vacuum line. Then I replaced them with the Champion 7879 and they work great.
Hope this helps.

When was the last time you had changed your plugs prior to 200K miles?
