We are all here because we are not all there.
I would not have pulled it without a bearing inspection70+ cold, 60+ hot. I think the clearances might be too tight.
Was it making any weird noise?

Wrong, if the bearings show metal contamination you are looking at a total teardown and cleaning, brushing the oil galleys, oil pump inspection.I did pull a main cap. It was grooved and had evidence of contamination. Plus the chrome looking flakes had me spooked. There was a bunch of gritty crap and metal shavings in the pan. Pure piece of mind I need to look at it and make sure. Worst case I strip it doiand it looks alright. New set of bearings and gaskets and off we go. Just a few weekends no biggie.
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.Wrong, if the bearings show metal contamination you are looking at a total teardown and cleaning, brushing the oil galleys, oil pump inspection.

[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.
I seriously hope this isn't the case. That might mean the crank is toast.[/QUOTE]This was my first thought too.

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

Some of the slivers had a chromish look. Like plating. I'm really worried that I run it and cause damage to crank/rods.
I did pull a main cap while I was under there and there was clear evidence of contamination. There was grooving And a few spots I could feel with fingernails.
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?
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.
Might be poor cleaning & residue left in the engine. Not sure I would be stripping it at this stage. Maybe install a new filter, put some miles on it, remove filter & check again. If residue is less or none, run it.
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..?
My bet would be that the bearing clearance's are too tight.So, moment of truth. Can any experts tell me their thoughts?
Pulling pan...suspense!

And now a couple main caps and a rod cap, and a look at a couple journals. Thoughts?

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 bet would be that the bearing clearance's are too tight.
Where did the metal come from?
I thought the same, I just didn't wanna say anything, as there are WAY more really experienced folks here than IMy 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.
Was thinking the same thing, couldn’t zoom in clearly.Just an observation regarding those pictures: It appears as though the rod journal oil feed holes are chamfered, but the mains are not. Is that the case for all? Optical illusion?
