Aligning the STC fitting

[smokersteve]

I just finished putting the truck alllll back together from replacing the STC fitting and some other modifications that are not related to the oil system.
It took ~1min to start, and it was not a real nasty start up. It took ~15 seconds once it got pressure, then the engine ran just fine once it did. I have a little y-pipe alignment leak but no biggy.

At the initial start I let the truck idle for ~2 min, turned it off, let it sit for ~15 seconds, re-start and it ran and started just fine, idle for ~2 min, reved it a few, then reved to red line, still good, I then turned it off.
I came back 5 min later to start it again and ti took ~10-15 seconds to start back up....

I did my best to align the updated one pice stc fitting:
Ford Part# 4C3Z-9B246-E
International Part# 1879930c91

But what I did was not good enough. I am guessing it is the fitting alignment and not the pump install....????
On the edge insight the inj pw at idle was normal (~1000psi +/-100), like it was before I worked on the truck.






What can I do to do a better job of aligning the STC fitting on the pump?


Thank you

Interested in seeing what anyone has to offer you.. I am doing my cooler this upcoming weekend and just found out I have an 05 motor as well. How much of a bizzo was it to replace the STC fitting? How much was yours? Did you get it at ford or international??

is the truck not wanting to start after it gets warms or something? you probably have lots of air in the system and they say it could take up to 200 miles of driving to get all the air out of a system, what exactly is going on with the truck?

my bet would be air in the system too, drive it for a while and see if it persists

bet its air too. It wont start normal until a good 10 mile drive at times. just like when you replace injectors.

$38 from an international dealership 30-40min from my house. I did some other modifications, but just the STC and now that I have done it once and much more familar on what to do, ~ a friday afternoon and a good long part of a saturday and sunday. Was it hard, no. a long process, yes. I think it is just time and making sure that the STC fiting is right.

No it has nothing to do with warmth. I can start the truck for ~1min, off for a few seconds, then start just fine.

Then if i start the truck for ~1min, then off for ~5min, it will not start up as quickly. It will rev slow for a second or less, then jump to 1,000rpm, then back to a normal idle.

......That is reassuring! I hope so. I will drive it for this week and wait for a change.

Thank you!

I have it on High Idle right now. The initial start up this time was the same as the others, key on start ~2 secons, light/soft ignition 1-less than a second, then rev to 1,000rpm, then to normal idle. I will let it be on high idle for ~ 10 -15 min.

[smokersteve]

it starts allot better today. Its not totaly back to normal but much better.

There is a TSB from ford about this issue. I assure you it is air in the system, if you screwed something up during the installation, you would know it right away, and as long as the 2 bolts through the stc to branch tube went in and seated all the way, then you are good to go. Anyway, the TSB basically states that after a high pressure oil system repair, it may be necessary to drive the truck pretty aggressively to get it all out, or let the truck just idle for about an hour or 2, that seems to do the trick as well. The TSB tells you to drive the truck at high rpm/boost as much as possible. I liked accelerating up hills to do it. You could floor it, but the uphill grade would keep you from driving too fast. 15 minutes or so of very aggressive, high load driving will fix you right up. Good luck and congrats on fixing the STC on your own.

yep, some wot runs are not only fun but helping your truck too.
