4.6 blowing out spark plugs

[rog50]

Have a friend that has an 1999 GT w/4.6 that has blown out one spark on the right rear and now has blown a spark plug on the right side any one had this happen?

Pretty common problem on the 4.6/5.4 modulars. They make some nice inserts for when they blow out. Only thing you can really do is keep a check on them from loosening

You can probably get one from your local parts store

O'Reilly has everything you need. Make sure you don't overtighten your plugs when you put them in.

And use a dab of anti-seize.

Psssh, I never use anti seize

You should have. The Cobra is already seized to the garage floor. :jester:

Ford recommends a particular type of insert. Check their TSBs!

There is usually a ticking noise (sounds like header leak, or bad lifter) just before she blows!!
