Don't take it so hard, you just been out of the loop, just a little harmless harassing is all , lol...

 

HI!... We were just screwing with you. Take a pill. It's like coming on here and telling everyone that the earth is round instead of flat. The sparkplug blowout issue has been very well known for about 7 years now. Just thought that you being a member here since 2001 you might of heard of it................

 

I had 2 shoot out on me in the course of a month. Its sucks and is a pain. The ford tech told me its cause either I used the wrong plugs or I didnt tighten them down well enough. I just rolled my eyes and walked away.

 

True. That's about it. Or you cross threaded.

 

If you use Motorcraft plugs and torque them to 28 ft/lb DRY, no antiseize, the odds of you blowing one are just about nil.

 

Good to see that Canadians are just a sue silly as Americans.

you will be found liable/ at fault for not properly torquing your spark plugs...

 

Yep, It's your fault, - get over it.

 

No..........the factory torque spec is only like 15 ft/lb.

 

Yea, it depends on where you read or look. This chart here is from the library -



It's real goofy as far as the charts, but in the real world, -who uses a torque wrench on plugs ? I never have , not until these issues came up and that was just out of curiosity. On the tapered plugs it's always been 1/2 to 3/4 turn after seat. That will put you at 20' lbs +.

In 99, the robots supposably OVER torqued the plugs, these vehicles where called back. If the consumer failed to bring it in, shame shame. Most of those models where caught at the dealerships, before sale. Info is real sketchy on that recall, I can't find any on it now , not even on ALLData. To search ALLData, you would have to have a 99 vehicle account being the site only reflects vehicle specific info from the manufacturer . I have read about that 99 model recall in the past.

BTW- The service DVD says 12-16' lbs lol.

 

The heads are Aluminum, and if the plugs were torqued too tight, the threads are easily ruined, and then the plug pops. Also, if the plugs weren't tightened enough, then there aren't enough threads to hold it in place - the plug could eventually back off and blow out.

Put some anti-seize lube and then carefully tighten them all to the specified 19 ft-lbs of torque. autolight double platinum plugs which are very easy on alluminum heads!! It has been 2 years for me with no problems changed at 105,000 now has 134,000

 

nice, four year old thread and still arguing

 

This is the wrong thing to do. Do not follow advice from this user. For one , Honeywell doesn't have an Autolight Spark-plug with the correct heat range for the 4 thread Modular motors. Honeywell has the Motorcraft Spark-plug produced to Ford specifications. You need the right plug for these engines to run correctly.

Professional testing has proved best to -

1. Use the OEM Motorcraft plugs DRY,- No anti-seize.
2. Torque to 28' lbs.

 

You won't get them too tight, the heads have been tested to 100 ft/lb without stripping.
