Got my oil analysis back and they reported high lead, could be a sign of bearing wear.

this was a cold sample and I plan on drawing a warm sample this time.

engine sounds good, no obvious slapping or knocking.

this is my 01 ap1 with 130k miles

Been doing some initial research. Lots of info out there.

 

Great judgement getting an oil analysis! Your next one may start to show trends.

Mid-drain sample? I intuitively think heavy particles, even microscopic, will tend to settle out and a cold sample hasn't been mixed well especially if drawn off the bottom. I had an alarming amount of Silicon in the cold sample I took several years ago. An outlier as it's never occurred again and I've been more careful regarding the sample draw.

AP2 engine universal average for Lead is also 2ppm. Mine has been 0ppm (zero) consistently since 2015 but I have half your total mileage. Royal Purple 5W-30 full synthetic which is still too thick until warmed up but does lube better on startup. I'd use 0W-30 if Royal Purple made it.

yes, mid-drain sample. I’m running Castrol 10-30 based off several recommendations here.

last month when I ran a track night at Road Atlanta I thought I was going to burn through some oil but consumption was the same. I didn’t lose any oil after 4 x 20min sessions.

I’ve got Dayton this month. I’ll change oil next weekend and draw another sample.

my drain plug has damage on the treads. I was going to replace with a magnetic plug or just an oe standard plug. I like the idea of keeping metals out of the system.

 

Thanks for sharing.. I have been doing this for my 911 C2S for a few years. After reading about thrust bearing on here, I plan to do the same for the S2000.

 

An analysis is good for the early detection of problems. And a clean result for peace of mind.

 

Drain plug threads issue, maybe consider a Fumoto valve. Get it on once, no need to impose on threads ever again.

 

I’ll check that out. This isn’t normally an issue for me. I went to a vo-tech school to be an automotive technician. Freshman year I stripped enough bolts to develop a healthy fear. I did cross thread a valve cover bolt in my wife’s old mirage. Fixed it with a helicoil set but I was still pretty mad at myself for doin it.

The previous owner crushed the hell out of the washer, looked like it had been reused a couple times. Still don’t know how the threads on the plug got damaged.

 

I still like the idea of the valve but this video is unintentionally funny



pros - no need to remove/install the plug anymore

cons - slow drain and you don’t get as much oil out

 

The lead is elevated for sure but it doesn't show a dangerous level where failure might be be imminent. Keep monitoring it and see if the numbers can trend downwards, if they trend upwards much higher you might have an issue.

Try a different oil with higher rates of moly and a better additive package, to provide an extra level of protection. The oil you are using is very average at best, that motor deserves better. I would invest in a higher grade oil with a better additive package, the additives will protect you if you get some oil starvation, which is often the main cause of bearing wear.

If the lead numbers get into the double digits then it will be more of an indicator that things are going south. I had an oil failure just after a bad oil analysis when my lead numbers hit 15 . Good luck.
