Just changed rod bearings

[Jersey_M3]

So I changed by rod bearing and did the 1200 mile break in period. Then changed the oil, didn’t send it off for analysis... maybe I should of now. Anyways Drive 5,000 miles and changed the oil and sent it to the lab. Anyone experience something similar to the attached photo Please note the lead levels. They are supper high but copper has remained stead with no influx. Also did a Valve adjustment during this period of time of oil use. Alsoooooo did 5 track events. I have the oil filter. I’m gunna tear it open when I get back from the weekend away.

Oil is Castrol 10w-60.
I use ceratek friction modifier

That does seem high. Which bearings?

oem from FCP euro

Any updates on this? I'd have already opened the bottom end by now. You also said track days, do you use leaded fuel?

What's a normal lead reading after a rod bearing change? I thought elevated lead was normal.

5 track events on an oil change? I've gone 4 and didn't feel good about it. I usually stick to 2-3 events. If oil temps went over 280, I change it.

This was my oil reports before and after a rod bearing chance (ACL bearings at 190k-ish). I did an oil change after replacing the bearings but before the interval shown on the report. Liqui-Moly 10w60.

Update on this is I am waiting for another oil analysis to come back. From the last time I posted I changed the oil, did two track days (12- 20 minute sessions) and drove around 1000 miles. We will see what the oil comes back like. Engine sounds top notch so really unsure what happened there yet. I even happen to set my PB times at the track. If the levels do come back elevated over like 10 ppm in lead. Ill probably purchase the new bearing under warranty from FCP and do the service all over again but purchase a high grade torque wrench for the job. Its the only way I could see an error in the procedure.

I cant get my car to go over 250 in temps of oil.

101 lead is crazy high, maybe some dirt during assembly caused a particle streak. What wrench did you use?

[Jersey_M3]

Yeah, it is high. I used a Teckton torque wrench (new)

One possibility is improper torque on the rod bolts which resulted in oval bore and subsequent bearing wear, which would explain high lead numbers. 101 is crazy high!
Mine was 2 ppm on fresh bearings after 5k miles on LM 10w60.

Same here - 2 ppm on fresh bearings after about 4k miles on LM 10w60. Stayed pretty much at 1ppm after 10k miles.

Nice, that's what I'm seeing too.

Time to get back in there 😢. Save the time on "break-in" and put it towards checking clearance with plasti-gauge on the new-new bearings.

Have you done this before. If so work you mind providing me a quick tutorial? I did not do this because it seemed like a waste of time to me. Anddddd here we are now lol
