Well, I changed the plugs and drive belt today. I was supposed to change the fuel filter also but it started raining. I didn't have any problems with the plugs as most people have posted on this site. I didn't want to mess with the fuel rails so I had to work around them, it was a pain in the axx, very tight. I did however come into something I wasn't happy with. There was soooo much dirt, debris, and what looked like sand inside all the COP's boot. You can see them even on the plugs below. How it got inside there beats me.

On the first plug I worked on, I put my plug socket in and I tried and tried but it couldn't grip onto the plug. After trying a few times, I used my flashlight and looked inside. This is what I found inside. Holy Cow.



I have no idea how this could have gotten in there other than from the factory. This is the first time I've ever change the plugs since buying the truck. NOBODY has ever worked on it where they would've had to remove the COP or the plugs.

They don't look too bad for 100,000 miles...

 

What is that in the first picture?

 

What does the gap measure on those plugs you took out?

 

Looks like one of those metal clips from the inner fender.. how did that get next to the spark plug?! those plugs look pretty good for 100,000

 

Have you guys ever heard of any engine that uses 2 spark plugs per cylinder?

Check this out. I bought my new Motorcraft plugs from the local AutoZone. When I was buying them, the girl at the counter asked how many I wanted. I figured I have a V8 so I need 8. She says "well, your car uses 2 plugs per cylinder so you'll need 16." I politely declined. Am I wrong?

 

I think she meant two valves per cylinder.

Plugs look par for 100K.

Good job.

 

There was a 2.3 that Ford used in the Mustang back in the 80s or maybe early 90s that had 2 plugs per cyl.

Yours does not.

 

2.3 late model ford ranger

Give him a 5.4 3v and see how happy he is.

 

i had an 88 nissan pickup i drove in highschool and to and from work that had two per cylinder. the thing put out some descent power. My f150 has 88,000 on stock plugs

 

The new 4.7 V8 Dodge/Chrysler/Jeep I think has 2 plugs per cylinder.

 

Rangers had that...it was "the german block" had 8 blocks for 4 cyl's my buddy has one of those and he says it gets really really good gas mileage.

 

Had a Nissan way back when that had 8 plugs.The other 4 were for emissions.4 on intake,4 on exhaust.
