OKAY..... I guess I'm a frikkin' idiot here. That pic helped my poor old brain a lot.
I didn't look close enough and didn't realize that the ports are a separate piece from the heads. As my oldest kid would say when he was little, "Stupid bonk my head off". I should have at least looked at the WSM if nothing else. So I need the UPPER gaskets.
None of the places I looked even said there were two separate ones that I noticed, other than the plenum and TB areas. Thanks, you guys.
@Cee Jay just want to say, as a person that will never know even 1% of what you know about these vehicles, I appreciate that you are willing to admit when you have a stupid-bonk-my-head-off-moment. I can only assume that others on this forum appreciate your candor, also. It lets us all know that **** happens to even the most knowledgeable and there's always value in keeping a conversation going because you never know when someone else is going to help you achieve that ah-ha moment. Thank you. Sincerely!
Okay so far, I have most of the gaskets and seals. The problem NOW is I have a box of parts and a cup of bolts, some loose hoses and a bunch of hanging things in the engine compartment.
Can anyone out there post (or send me) some pictures around the intake plenum and throttle body? Even with the T-hose may help, but what's underneath is where the stuff in laying in a pile. I sure wish it hadn't been given to me in pieces. There is even a vacuum hose piece cut off after a T that I have no idea where it goes, or comes from, or why it's even there.
........................
Humour me, how does in the inside of the air resonator look? I'm with @mhminnich , I'm confused how this could have happened. However, though not optimized, it doesn't seem catastrophic if it rotates freely and without play or "smoothness".
How are the airboxes? The MAF?
Have you put a scope in and looked at the valves?
I've seen some put nylon hose over the boxes as a means of increasing flow (yeah, whatever) I wonder if this engine ate one?
I know you'll lick the problem. Just a matter of time.
All the plenums and air boxes and ports look wonderful. They have the usual EGR grime, but there's nothing can be done about that. No chunks, build-up or foreign material. I ultrasonically cleaned what I could and carb sprayed the rest, and everything is great. I scoped the intake valves, those all look great. I did run the fuel injectors and the spark plugs through ultrasonic, so those should now be even better. The plugs look like they were replaced not more than 20,000 miles ago, nearly pristine (other than the nice light brown coloring).
Nobody has answered a question I asked in post 3 or 4 or somewhere.... How would a person check the flow of a catalytic converter other than removing it?
That was the ONLY code that the crap-shop actually stated. Tear an engine apart cuz a clogged cat? That's incompetence. I don't have my lift yet cuz I'm too broke to get it yet, unless someone wants to let me borrow a forklift so I can have one shipped to me... Anyone?
Okay, this is embarrassing for me, but my kid doesn't seem to care either way.
When he bought this thing, lots of the intake parts were powder-coated a muddy red. It's a pretty good job, but a crap color. I've been hiding this best I can so far. Also no engine cover. I still offered to recoat them black or silver. No dice.
if it wasn't 106° on the driveway EVERY SINGLE DAY 🥵 I'd pull the intake tube off and shoot you some photos, but, dang it's hot! Putting it back together nearly did me in. Lol
No way to check a catalytic converter in situ on a non running vehicle that I know of and I assume that's what you're asking? Of course without a lift, removing it is a major PIA.
The hell is this, and where does it go??? I sure wish he would have gotten a 5.0 instead. At least I'd have mine to reference.
Cee Jay, that looks suspiciously like this gizmo, picture below, which lives in the trunk, on the left side, behind that small black cover panel. It's the same panel you remove to get to the battery charging/jump start connection. This picture is a different angle from the one you posted. And I have no freakin' idea WTF it is or does. I been through all the electrical sections in the shop manual, and I looked through all the online parts breakouts. Stumped.

Maybe this helps? Seems to be some kind of radio antenna filter?
The thing I'm asking about is hard-wired into the electrical harness at the firewall, so pretty sure it didn't migrate from the boot.
Also, I saw on a picture jminnich went me where it attaches, so while I still don't know WHAT it is, at least I know where to put it.
