I definitely wouldn't ignore the signs. If you want to save the engine from any more warping than it might already have, do a rebuild!

 

Man J (or should I say zero) your story is crazy every time I hear it and is really one of those rare instance when there is no smoking gun. It makes even crazier that it was the mains that went. Guess we will never know just what happened, lol

 

Yup that is the best way to describe it - crazy. Most of the time I drive like an old lady to be honest, I haven't seen 9000 rpms all that much in this car. Jordanksartell took the engine apart for me - one of the best S2000 mechanics out there BTW - and to this day we still don't have definitive proof of what caused it.

 

Hey all,

See attached photo. I got my report back rather quickly! All looks good I believe. I think I caught it just in time.

That is good news ! It looks like you have been saved of any bearing damage, the numbers look good. The only thing that may be slightly elevated is aluminum but it still looks reasonable. Oil viscosity is a bit low (thin), it sheared a bit. What oil were you running ?

Unlike some cats, your engine won't have nine lives, don't let our oil get anywhere near that low again as you might not get so lucky next time. But I'm sure you already know that.

 

Warping? Please explain what exactly warps during an oil starvation....

The first thing to go during an oil starvation are bearings. Unless you keep running the sucker and melt the cams into the head due to bearing pieces or other debris blocking the VTEC solenoid screen, those will be the only damage and warping will not be associated with it.

One could say if the OP saw elevated levels of bearing wear in his analysis but hadn't yet gotten the gold flakes, he could more than likely slip in some new bearings and act like it never happened. The only wear would've been on the babbitt which is much softer than the steel of the crankshaft. It's the steel backing of the bearings when worn down beyond spec that cause severe damage to the crank.

 

Now you did just add 3 qt. of makeup oil and then sample, so they results could possibly be a bit skewed. I would pull a sample from your next oil change for good measure.

 

I always wondered if Blackstone would use the make-up oil amount to adjust their readings, since they ask for the information with the sample.

 

looks like u dodged a bullet for now that's the good news. keep a close eye on the oil, if your burning a ton of oil look into why and where. it will be cheaper to fix before you grenade the motor.

 

No, there really would be no way to do that. They typically will take it into account when commenting. I wouldn't see a huge issue of it was 3 qt over 3k miles, but it was 3qt all in one lump and then it seems the oil was changed rather shortly after.

Jordan, is it safe to say with bearing wear high lead AND copper would be tell tale? You can have a bit of lead with a particle streak and iron comes from various forms of wear, but wouldn't copper be a strong indicator of going beyond the lead Babbitt in the bearing?
