512Stroker
We are all here because we are not all there.
I would not have pulled it without a bearing inspection
Was it making any weird noise?
Super bummed. New motor. Bad bearings?

Wrong, if the bearings show metal contamination you are looking at a total teardown and cleaning, brushing the oil galleys, oil pump inspection.
That's kinda what I meant. Unless all the other bearings look great (doubtful) it's a full teardown, decontamination. Not going to be fun but I gotta do it.

I always thot everything on a hemi was fun, back in the day , except the tie rod tube pan removal --------

[QUOTE="dogbreath, post: 1973627170, member: 12420"]If its a stroker crank with a chamfer , its easy to get the top and bottom rod bearings and or rods mixed up so that the rod and or bearings are riding on the chamfer , will cause issues similar to what you are seeing.[/QUOTE]
This was my first thought too.

I seriously hope this isn't the case. That might mean the crank is toast.

If it doesn't have much run time on it I doubt it's hurt.

I'll probably pull the pan tonight and inspect a few rod and main caps. We'll see soon enough.

Just noticed you run stock type fuel pump. No issues with fuel vaporlock? I think I get that in my dart 360. Also do you run vacuum advance on distributor or not?I pulled my 408 Six Pack after 4 mins of running due to a bad rear main seal. I understand what your going through

Chrome look... like cam lobes?
You already know the mains got trash in them. Rods may not be any better. As already said, it should all come apart for cleaning and inspection.
That's my plan. I was wiped out yesterday after work so I couldn't really get to it. Hopefully I'll get some time today.Chrome look... like cam lobes?

Haha. If I built it it wouldn't have contamination issues. That's what I gofor paying someone to do stuff for me. This time will be different.You didn't do a marathon build on that on a livestream did ya..?
So, moment of truth. Can any experts tell me their thoughts?
Pulling pan...suspense!
Windage tray and oil pump off...
And now a couple main caps and a rod cap, and a look at a couple journals. Thoughts?

Some shots of the thrust bearing...

Wow! That's not good..

My bet would be that the bearing clearance's are too tight.
Where did the metal come from?
Still too early to say. I only pulled a couple main caps and a rod cap. Full teardown to come. Looking closer at the main cap I can see what looks like pitting or embedded particles. I agree tight tolerance plus probably contamination. Glad I'm doing this.
My 1st thought was too tight on clearance. But the pics seem to also show the dreaded tracing/tracks of debris too and some general "grittiness" too. So from what I see, looks like maybe a bit of both. Let's hear from other folks smarter than me.

I thought the same, I just didn't wanna say anything, as there are WAY more really experienced folks here than I
Was thinking the same thing, couldn’t zoom in clearly.
Did You do the aft & fore raps on the crank to seat the thrust faces before torquing the cap? You're using studs's, be sure the pass-through holes aren't too tight to the stud shoulders, could be pushing the cap when You torque it down. Try J.Rob's technique, drill a small hole thru the upper shell thrust face that goes into the main feed to oil the thrust faces directly, and did the crank oil passages get a thorough brush & flush? Could well have been machining/finishing leftovers. Good luck!
Wow. Clearly contamination. Is this a stroker? I am not an engine builder, but I did assemble my 418. I saw no rod to block contact, but the cyl bottoms need to be clearanced, along with normal clearance checks. The crank will probably need a polish, new oil pump if it is hurt and all bearings etc. Friend build it or a shop? The contamination was bad, it made through all of the bearings, not just the first oiled.
I feel bad for you, Good cleaning and parts replacement to you. GOOD LUCK.

Mic the journals check the numbers order correct bearings eh? Then plasti gauge on assembly.
