A while back I posted about how I replaced the injector o-rings, and suspected the new ones failed after my truck burned through 8 quarts of oil in 200 miles.

Well, all 8 injectors looked like this when I pulled them out. Notice the chewed up looking o-ring:



So take note. Never by cheap o-rings from an auto parts store.

By the way, the composition of those cheap o-rings is completely different than the Alliant replacements that I put in.

 

Yikes, that definitely something to keep in mind.

 

Looks like a squirrel got hungry and decided to snack on the O-ring!

 

I've said this for years and it holds true for whatever you buy:

AMERICA NEEDS TO GET OVER "CHEAP".

One of my biggest gripes concerns the sheer number of posts started with, "Where can I get the cheapest ________?"

There you have it.

For these trucks, dealer only. Be it International or Ford.

 

What Cody said. That o-ring looks like it has been eroded by something, high pressure oil? Just as Curtis has done, I have learned the hard way too. Get original equipment quality or better.
