Personally, I feel "cab off" is taking on a life all it's own... one that it may not deserve...

 

For anyone that may have missed this, I offer, for your reading pleasure, this travesty

I have seen that before, but I gotta ask. WHY THE FUCK WOULD YOU WAIT 100,000 MILES TO PUT PLUGS IN ANYTHING?!

Aren't spark plugs guaranteed for 100,000 miles under some emission warranty? Aside from that we have seen the plugs come apart at 60,000. Fortunately I have not had to deal with one of these personally. It seems like it's always one of the back cylinders too but nobody has ever taken a cab off in our shop to get a plug out.

Here's the thing.... the "expected service life" of the spark plugs is 100,000 miles. This far too long for the 3V spark plugs to remain undisturbed without expecting problems at the end of their service life... But, this recommendation is under "normal" conditions.

 

Remembering that very few people fall into the "normal" operations category, we trip on down to the "severe service" recommendations which has a spark plug expected life of 60,000 miles. Which would probably be right about hwere a sane person would recommend inspecting the spark plugs in any motor...

 

So... is the problem with the spark plug? The head? Or is it with the people that are unwittingly exceeding design limits?

Not to stray too far off topic, but I just recently had a high mileage Focus (185,000 kms. to be exact) coming in on the hook with a busted timing belt. It was a 2.0L Zetec. There was NO evidence of neglect to this vehicle. There was NO oil contamination, nor did the timing belt idler or tensioner pullies fail, only the belt itself had frayed. IIRC doesn't Ford recommend a 200,000 km interval for timing belt replacement (which to me personally, is WAY too long)? Yet, on a 1998 Escort ZX2 or Contour/Mystique equipped with the SAME engine, and the SAME timing belt, the recommended replacement interval is only 100,000 kms. (which is a little more in line), if I'm not mistaken? For this reason, I generally have very little faith in Ford's recommended service guidelines.

Seems that it varies SO much between models, its unreal - like you said Mike - One year Escort? 96,000. Another year? 192,000.

 

Random number generator, for the win.

I agree. Many times recommended service intervals are market driven, not decided by the engineers: the competition says 100,000 miles, so the OE says 105,000 miles just to have the edge. IH did this with their DT's on valve adjustment and got burned with excessive clearance beating out the rockers and valve tips. They issued a TSB reducing it from 100K to 12 mo/50K. I've seen several other instances of obvious market driven intervals, too, such as lifetime ATF, coolant, or fuel filter lifespans. Keep in mind the OE's first interest is to get the vehicle out of warranty, and that's it. From then on it's not their problem.

 

A lifetime fuel filter? Who the F@#! are you kidding?

 

Use common sense......!

They are kidding the consumer.... it ain't the car that's bad... after all it ran for umpteen thousand miles with no problem. Ergo, it must be the tech that's no good... /forums/images/%%GRAEMLIN_URL%%/2cents.gif

 

Automotive customers can be a strange breed of cat... their car represents their "freedom" and they WILL shoot the messenger if the news is bad.

I have a hard time taking fords reccomended service intervals seriously. I have an 06 f-250 that has just turned 30,000 mi. I took a look into the operation and maintenance manual for reccomended fluid change and was very surprised at what I saw. It said to not even remove the plug for the rear end unless a visisble leak was seen, that the fluid is "synthetic" and good for the life of the vehicle. Now I dont know about anybody else but I was taught from the old school. Where you check ALL the fluid levels at oil change interval. And the phrase "oils and filters are a lot cheaper than a failed component" was hammered home. Needless to say the fluids were quite expensive but next weekend I will be changing the fluids. Like I always say "Big trucks, Big bucks. Its the nature of the beast"
