It all started well enough, I brought the truck into the shop..... After that well, things didn't really go as planed. First off my fuel pressure gauge that I installed a month ago was resting on 80psi and that was with the truck shut off. After further investigation I found that the grease gun hose that I had used had swelled up on the inside and was plugged and my high dollar, oh I mean cheap *** liquid filled gauge was shot. Depending on what angle I held the gauge at it would change from 55 lbs to 80 lbs.

OK back to the task at hand, the injectors. The drivers side went well I did the quick method, pull the old injector out and replace it with the new one. After I had installed the new one I would check the old unit out for torn or missing O-rings and if the copper washer was still there. With the driver side done I moved to the passenger side, that rear bolt on valve cover is a beggar. Anyway pulled the front injector replaced it with the new one and then....... Oh No the old injector had no copper washer. After a bit of frustration trying to get the old washer out it became clear that it was a futile attempt as I was detecting anti-freeze in the cup.

I now have I new tool and a set of injector cups on the way.

Thanks Jim for all of your assistance and your fine service.

Well that sucks but look on the bright side you get a new tool

 

on the brighter, bright side you found a problem that would eventually have you pulling the SOBs out again!

 

That's what I was thinking.

 

Alls well that ends well!

 

So I think I have been neglecting my coolant system. I understand that can lead to problems like I am having. I did post another post about anti-freeze https://www.ford-trucks.com/forums/1...l#post10407882

Sense I couldn't install my injectors I decided to fix some small stuff and noticed that my coolant tank reservoir was dirty on the inside. I took it out of there and tried to clean it up some man there was a bunch of junk in there. Let a lone this slime all over the top part, that was probable a little bit of fuel contamination, maybe.

Anyway maybe going forward I will do a better job at maintaining the truck.

 

That is why I'm no fan of the "quick method"...

Pull the injectors and inspect the cups... Then drop the new injectors in.

Sucks you have to replace the cups but glad you found the problem...

 

If you pull the cups does coolant leak into the cylinder or is it already out of the heads?

 

It would leak or more like pour probable in the cylinder if you didn't drain the coolant first. I don't exactly know what it looks like with then removed but I suspect with them removed it will open up into a water jacket.

 

Oh yea good call on draining the coolant first.

 

OK I received the tool and injector cups today. Thanks Jim for your prompt service and all your help.

I didn't have much time but I did pull the front two cups from the passenger side, the very front one was the bad one. Is it possible that the injector did not have a copper washer? Looking at the bottom of the cup on the inside the marks that are there, clean portion is not the same as the one with the washer.

The cup that was leaking was cracked, two cracks running from the bottom up the cup a little and then another running around the bottom between the two cracks.

 

Does 168 in lbs of torque sound about right for the glow plug's? How about the oil deflector tube my manual says 106 in lbs, but it also says the injectors should be 108 in lbs not 120 in lbs like I have read here.

Thanks

 

GPs 168 in lbs. Both retaining bolts 106 in lbs. Thats what I have.

 

I did 120 in lbs on the injectors

 

I'm sure something in the ranges mentioned are fine. We are talking inch pounds of torque.
