Oil swirls after rebuild
#47
It’s just Metallicy swirls which takes me away from coolant I took some in clear jars one from pan from filter oil to see ive built a 7mgte myself and an old 302 the ls platform is newer to me honestly messaged the engine builder with pictures and said where do I go from here. I’m not one to pass blame but all I did was valve covers and bolt it to the trans

Pulling the heads isn't that big of a task. To me a "full rebuild" involves a bare block and a machine shop. Maybe get one of those tests for coolant and test your coolant for exhaust gasses?

So a new rebuild which got washed with coolant wouldn’t need a full build down to the block? Asked engine builder if he checked for cracks no cracks he said I know the guy was very thorough not sure I’ll get the coolant test kit not sure how long black stone takes for an answer

No way that much metal powder got left in a block during a rebuild.
Even if it had, there's only one way it could have got out from inside the block; and that is, through the bearings. Unquestionably the death of the new motor if so.

Not trying to be a dick but if there is a bunch of gritty material in the oil why no evidence in the oil filter?

Think about it this way, you haven't even leaked enough coolant to milkshake your oil. Just find the repair and don't worry about it, the internal parts are almost certainly fine.

maybe the oem oil galley dumbell is flowing to much it’s not gritty to the point where I can grind my fingers together and feel a bunch of grit it’s very fine super fine which could be why it’s not showing in the filter? I’m going to to a leak down test tomorrow and see if I have a coolant leak I just feel like I would see the level go down and it would be more milky than a shimmer.

That's metal. Coolant in the oil makes it look like coffee with cream at first, then gradually turns more to milk shake. It's not coolant. Something inside there is disintegrating. Sooner or later it'll show up. Best to catch it before it does, if possible.
The oil filter only catches particles down to some finite non-zero size. Powder like that can pass through. As said earlier, try catching it with a coffee filter, maybe dissolve a few ounces of it in lacquer thinner first to allow the liquid to go through easier; and see what it really is.

Tried the coffee filter nothing in there, went to machine shop showed the oil said it’s a little off but could be the break in oil. and he listened to motor says little valve train noise which is normal with the setup and to send it to black stone see what they say and go from there I guess for now I’m going to drive it 500 more dump it again
