This what my magnetic plug looks like after pulling it from the pan:

Notice the hair on top of the plug. Haven't seen the filter yet or examined the oil itself. Should I be concerned? Engine has the 500 break in miles only, but two dyno runs (for tuning).

Eahhhhhhhh,,,, Even though it LOOKS BAD,,,, I would say that; unless there's big CHUNKS, I wouldn't be too concerned.

On the next oil change, if you see the same collection,, I would start paying attention!

Cut the filter and look for chunks and babbit. If you don't see any, continue to monitor.

Where did you get the engine from???

If it were me, I would send them the picture of the Mag Drain plug and let them comment.

That way, you put the ball in their court.

This is great advise. I recently sent in an oil sample on a new engine with less than 3 hours on the track on it. Lab said everything was fine. I cut the filter and now the motor is out being rebuilt. Look deep in the folds of the filter, not just on the outside material.

Armycop

Good idea I'll cut the filter when I get I get home. No chunks in the drain pan just some old oil residue.

Hi Bill! Motor came from LaFontaine Chevy here in MI. it's the GM 525hp motor with the ASA cam.

Personally, I would be concerned. Definitely get a dialog going with whomever you got the motor from as suggested above.

I suppose that much gunk could be left in the motor from the manufacture, but that seems very excessive to me.

I would not have done the two dyno runs during the break in, certainly not the early part of the break in, but it should not have been an issue either.

i would be concerned if it did that on the next change. if the bearings were just a hair tight and or assembly lube wasn't slobered everywhere and you didn't prime the engine i could see some wear happen in the first few minutes

if you see that again it's something i would be concerned about.

personally i would drive 1k miles and check again just because i'm curious.




is a how to manual on break ins. this is the ideal method. you don't stress it but create massive vacuum which helps seats the rings, loading the engine dropping into that lower gear is such a great way to seat rings

the dyno redline break in method is how some F1 teams break in engines, some still do it, i just personally prefer the video method since it achieves the same result with less stress

That's not enough that I would be concerned. Most new engine break ins I have done have simila results. As stated before keep an eye on the next change. The new block may have had slight machining dust that the hot tank doesn't always get. This is part of the reason for after break in oil changes.

Nope. New motors will have that. Everything is working in. If you see that every 500 miles, then you have an issue.

Wipe that on a paper towel and show it to us again. It's not uncommon for a new engine to have some of that, as the parts wear together. As long as it is real fine and not copper colored.

It's completely normal, especially on the first couple oil changes.. Cruise on and don't worry about it. If you start seeing copper glitter or chunks, then start the worry. The fine shavings and "gray paste" on the plug is normal.
