Important Tip for 5.4 owners

We have had instances of the 5.4 spark plugs breaking when being removed. Ford provides us with a special tool to remove them, however if the rear plugs break it requires removing the head or the if both break remove the engine. Scheduled maintenance suggests inspection or replacement at 100,000 or 160,000 kms depending on model. I reccommend you have the spark plugs inspected before the warranty expires. Either way it is an owner cost to inspect/replace but should they break warranty covers to remove them, saving a potentially costly bill.

Thanks for the heads up..
Maybe I'll have this checked out since I'm boarding the 60k.. (58,550km)

Have an idea what spark plug change would cost?

That's for the info.
Do you have any information on the problem of Lightning 5.4 plugs blowing out of the heads (the 4 thread heads-think 2000 to early 2003), have heard that Ford will now fix for free, even out of warrenty, is this true?

I'll have to look into that one for you. Any after warranty adjustement, goodwill whatever you want to call it is now dependent on if the owner can prove maintenance at a Ford dealer. Then the guidlines are are under 100,000 k. I'll check though

I blew 2 spark plugs rite out of my heads last year when she was at 190000km. I got ford to send the heads out and got all eight holes machined.


I only drive in the city, to get out of it!!!

It's a 2 1/2 hour job at 90.00 per hour.
about 15.00 per spark plug.
If a Cod is faulty then they are about 145.00 each.
If it's just the spark plugs then about 300.00 to 350.00
