hi folks i need to change the #7 spark plug in my
07 chevy 5.3 engine could anyone tell me which one
it is.it burns a quart of oil about every 900
miles.and it fouls out the #7 plug first last time
was this past spring.engine light come on local
mechanic put his little tester thing on it said it
was #7 cylinder so i just changed them all now it
says same thing so i think i will just change that
plug only but neither of us know which one it
is.thinkin maybe the valve seal might be leaking
or broken oil ring not sure any help will be app.

Change the cool out too. There are even high powered MSD coils.

Swap 7 and 8 coils and see if the problem moves.Put a new plug in 7.
