7.3L Econoline injector cups

[Alex Bruene]

If you had a head off of an Econoline for a cracked injector cup, how many cups would you change? I think the answer is obvious... or maybe I'm just crazy, but I thought I'd just throw it out there...

Neither.

 

We've never done less than 8 cups in an engine!

 

 

Sooooo, after you do this gig and it gets fuel into the coolant, how and what are you going to say to the customer? /forums/images/%%GRAEMLIN_URL%%/readthis.gif I'd like to be there to watch your little dance. /forums/images/%%GRAEMLIN_URL%%/grin.gif

 

Is there evidence of overheating? Many injector sleeve failures are a result of getting hot. I tend to think they are a secondary failure, not a primary failure......

 

Good Luck!

Well, being a rental truck, it's hard to say if it were overheated, but I'm sure abused. It was a warranty job, so there is not much to have to tell the customer. The unit in question had the right head removed, and only one cup replaced... I just don't see the logic in not replacing all the cups on that head... that's the reason behind the poll.

Oh, my God. Who's the brainless critter that made that decision? What do they cost, $5, or something? /forums/images/%%GRAEMLIN_URL%%/scratchhead.gif
