96 GMC Sonoma, did some research, found this…

Same engine it seems, but where the fuck do you put the oil?
Just pour it over the engine. Make sure you give it a good thorough coat. It’ll work its way in.
I just mix it in with the blinker fluid. 12:1 ratio
I couldn’t find the OIL cap but I found one labeled 710 but I can’t find any 710 fluid.
It should be around here:

It might be underneath some hoses or similar due to PDO. If push comes to shove, you could always use a skinny funnel and pour it down the dipstick tube…
Turns out, it was hiding under the duct tape on the air intake the whole time, on the driver’s side. Guess the video I found had me thrown off a bit. Like, they’re basically the same engine, but the video covered a 98, we got a 96…
Is that an oil cap in the right of the picture? Just in front of the duct taped intake. It’s a black cap with amber writing on it, so that’s what I suspect. If it goes directly to the engine, that’s it.
That’s power steering fluid…
Oops, don’t want that. Could you take two more pictures, I’ve from the left and one from the right? Unless that red box someone drew got it.
The red box post is where it’s supposed to be.
It’s getting dark right now and my camera sucks, so no more photos, at least not today.
You drizzle it like salad dressing.
Drizzle it!
Yes mmhmm, I see, that certainly seems to be a car of some sort.
Just pour it over like olive oil on charcuterie and you’ll be good. Trust me
It’s bound to find its way where it’s needed, eventually.
Hey there. I had the Chevy version of this truck once upon a time. The location depends on what engine you have:
If you have a 4-cylinder, cap should be near the center on top of the engine. If it’s the 4.3L V6 the cap will be off to one side, but still on top. I think we’re looking at the v6 here.
Look for a black or yellow cap, it should say OIL.
Can’t find. Should be obvious right? But we can’t even find it ☹️
Is there any way you can take a picture of the engine from directly above it?
It should be more towards the passenger side, maybe more forward then center. It may not say oil, but rather 5w-30 or something like that.
Yes, that’s exactly where it should be, but we’ve been investigating this thing for about a half hour now. We simply can’t find it, and the one half obvious thing top side is for power steering fluid, not engine oil…
It’s getting dark right now here, no more investigating tonight.
The video link I found seems to be the same exact engine though… 🤷
Looking at this, you better put the oil in a different car.
His previous vehicle ran fucking great! It just had an unexpected situation, we highly suspect arson, but no proper evidence as of yet…

Anyways, now we got this beater Sonoma, but at least it runs, and pretty smoothly at that for being 30 years old.
We found where to put the oil, it only needed ~3/4 of a quart. I’m pretty sure this one needs oil more than the last one…
Simple: try putting it in each hole and if the car doesn’t work just take it back out
Usually on the top left near that jumble of hoses where the valve cover is, there is a filler neck sticking out. I can’t see it in this picture though.
And that’s the mystery of the day, where do pour oil?
Going by all the hacky looking fixes, it may have snapped off or been removed for some reason. I’d rustle around those hoses in that area to see if you can at least see the valve cover and feel around for an opening.
Worst comes to worst you can fill it from the dipstick
In the engine.
I expect the car would have a manual with detailed instructions. Or google the car model.
We found it. For whatever reason, ours doesn’t have the extended filler neck tube, but at least it does have an oil cap, its just buried down in there.
As far as the manual, this thing doesn’t even have a glove box, half the dashboard itself was just straight up cut out and covered over with duct tape. I’m pretty sure the previous owner did that to make the passenger side into something of a bed for semi comfortable sleeping. 🤷
