There’s been a lot of knockoff motorcraft parts out there these days! Here’s the way to tell.. see the square stamps? The square stamps indicate these are the good ones. If they have a circle there those are the counterfeit ones. I got lucky I ordered these through Amazon… from now on I’ll order motorcraft parts through a reputable dealer just to be safe. Glow plugs are not something you take chances with. I’ve said it before and I’ll say it again NO autolites!
Oh boy Tinky is alive again! I’d like to say I helped but I think I just got in the way lol. My brother and friend made quick work if installing the cups, injectors and putting everything back together.
Here’s some pics I took in no particular order. The tool worked fantastic much better than trying to hammer them in.
Two of my injectors had serious pitting on the seal surfaces—bad enough I don’t know how they didn’t leak . Not sure what would cause that! Luckily for me my friend had a spare core engine that he removed from a truck Friday. Swapped injectors (same AB code) and good to go. One of those bad injectors was a reman unit so someone has been into it before. Knowing what I know now I think I should just suck it up and buy a full set of injectors but for now I’m going to run it.
Took some time to flush out the coolant but I think it’s good to go.
One thing I’m glad we did was crank the engine over with the injectors out of it. There was a lot of oil in the cylinders from taking the injectors out. Good thing we did it prevented a hydro lock.
Wow, that injector is corroded! I wonder if coolant got to it somehow. When I replaced the o-rings on my injectors, I used a vacuum fluid evacuator to suck all the oil out of the heads. Then I cranked it a few turns with the glow plugs out to make sure the cylinders were dry. It did the job, but I had lots of cranking later to get the oil back in the heads. It ran rough for a short bit. The engine finally cleared up once I got it to the highway and ran it hard.
I was informed on FTE that cranking without the injectors in was a really bad idea because it will push oil into the heads—yikes. I may have dodged a bullet on that one. Put the injectors in and crank it without the glow plugs in is the way to do it. Now I know I’m still learning these trucks and their unique injection systems
So the gutless until warm was my ebpv valve sticking randomly when I fist bought it and that hasn’t been an issue with all the delete stuff I did.
It smoked for a bit today during startup but nothing I’d consider to be out of the ordinary given how cold it’s been. I drove it up to Richmond and helped my dad haul off a tree that fell from that snowstorm. So I ended up putting some miles on it going from there to the landfill and back home. Seems to be running just fine I haven’t seen any fuel in the coolant so I hope those cups are holding for years to come!
