Found and read the whole thread this morning. Good quality build. Glad to see the truck is holding up!

I went the KISS route with this one. I wanted the look of a construction foreman truck. Clean, but rugged, a little old school, subtle, modded, but effective. Everything done with a purpose. I'm hoping to see 250k-300k out of it before I upgrade. I'll be going the diesel route I think.

Whale ****.

Smoothing out the dinks in the piston to prevent detonation points as it passed a feeler gauge check. Happened at idle while I also happened to be taking a shxt in the house.

Need to find a full set of valve springs and push rods, a single intake valve and guide, locks and retainers as well as a valve cover and gasket set, head, intake and exhaust gaskets.

Anyone know of a solid place to source OEM spec stuff? All I'm finding is springs for upgraded cams, or "OEM" stuff from sites I have never heard of/trust.

Parts ordered to fix the truck. If I missed anything please let me know. I've been totally frazzled the last couple weeks dealing with all my vehicles basically breaking down.l

Got everything back together today and fired it up, I have no pulse on #7 and a pretty significant oil leak at the right rear valve cover. I'll investigate that stuff tomorrow. But everything else seems to check out. I also have a blown right front strut so that extra from my Bilstein fiasco will actually end up serving a purpose. Blessing in disguise I suppose. So far I'm pleased with the results.

Diagnostics results:

I have a shot injector. Swapped it between cylinders and it followed. Showing no pulse on #7, when I moved it to #5 it was dead there too. Noid light shows good signal to the injector, all others operating properly.

Oil leak ended up being a tear in the valve cover gasket. Got that replaced and it is all dry now.

Replaced the injector today, all 8 ar now showing even pulse.

Still running terribly, high idle rpm, lean codes, and a high airflow vacuum leak code.

I'm starting to get frustrated now. Gonna pull the whole intake again, make sure the new seals are still in place and not damaged, and then seat the injectors on the bench to ensure they aren't loose in any way.

If that doesn't fix it, I have no clue what to do next and I'm about out of patience with it being down since memorial day.

All of my vacuum lines are hooked up. All of the boots are good, everything is plugged in and nothing is pinched. If I had hair, I'd be pulling it out.

Alright so I pulled the intake and found #5 injector was double o ringed into the fuel rail. I rectified that and noticed I had a small hole in the intake on each side of the injector hole.

Upon further inspection and after a few beers....... The number 5 intake runner is *****. I really don't know how I missed the 5 gaping breaches in the runner through melted plastic from the combustion events blowing back through the hung open intake valve. We are gonna go the sloppy route for now but I'm gonna be working on finding a new intake for this thing.
