Well after 150 miles this is what my drain plug looks like, once wiped on a paper towel there are no hard pieces of metal, just a grey pasty grease, looks like grey sludge. I'm hoping it's normal, I have since sent off a sample of oil to be analyzed and have ordered a filter magnet to hold any particals to the walls of the filter. I plan to wait on the oil analysis to come back before driving it again.

a filter magnet? never heard of that.... any particles that go through the filter will most likely be filtered out if you are using a quality filter. unless you mean drain plug magnet.

my suggestion is to wait for the analysis, and if they say its "ok" i would slap some new oil in it, and then drive it around for about 20 miles and then drain it again...

this time when u drain it tho, grab a CLEAN empty drain pan, something you can visually see into, and then grab a white piece of paper and hold it under the stream of oil...if you see any type of Alaskan gold rush...i would plan on yanking the motor and pulling the oil pans off to see whats going on with your bearings...if it passes the paper test, just visually look into the oil, you should see some type of metal flake to the oil for a brand new motor, not extremely gold tho.

brand new motors break in, just the nature of them, you will see larger pieces of metal from ring seating and smaller pieces, the engine builder could have built the motor somewhat tight, it just depends, do you have a blueprint or a build sheet of this motor?

hope this helps,

Yes I read some good results on their web page, they had the oil analysis done with and without the filter magnet, there was a reduction of 80% or so in the quantity of metal in the oil.

I'm probably just paranoid but I've been to hell and back with this motor, this isn't the 1st time I've seen this sludge on the plug, not long after on the last motor the rods started knocking so I hope that won't be the case this time.

Does anyone posting here have any experiance with having owned a new motor with a magnetic oil drain plug. I'm wondering what others drain plugs looked like after the 1st or 2nd oil change.

Looks the same as mine did after the first and second oil change. I was running a magnetic drain plug and also a magnetic filter (Power Enterprise Mag Power) on the first oil change. Unless the oil analysis shows something abnormal, I wouldn't worry about it. BTW, oil analysis for oil used during break in will likely be high for any or all of the following: iron, chromium, aluminum, silver and copper. It's just normal break in of the cylinder walls, rings and bearings.

Cool, thanks for the info! Yea the test results came back high but they said it could be normal for a new motor.


During my most recent oil change I wasn't thinking about doing an oil analysis until after I had pulled the drain plug and the oil was already drained out. Unfortunately the oil was drained into a dirty container so I couldn't use that oil for test purposes, In order to accumulate enough oil for the test I had to jack the car up on the driver's side to tilt the oil pan as I only was able to get about 1oz of oil out with it sitting level. Due to the fact that the oil sent in for testing was oil that was sitting on the bottom of the pan my thoughts are that oil may skew the test results as it was collected from the bottom of the pan with any trash. That sample probably isn't indicative of the other 5.5 quarts already drained out. Also my turbo started clanking away after 100 miles of driving, the jounal bearings are shot with lots of side to side play, probably from the last motor. I'm sure that didn't help the test results either.

i dont have a "fresh" motor. just a used JDM GTE. but i put a magnetic drag plug in it. and everytime i pull it, the plug looks close to what yours does just not nearly as much. i just think it's doing it's job.

The content of that plug look dangerous to me IMO. The only time I've seen my magnetic draig plug looking like this is after a rod knock. I also put some super magnets in my oil pan in the same engine just in case and when it was torn open again it became apparent that magnets are not the panacea as the rod and main bearings (generally the items that are absolutely critical) aren't made out of steel and do not adhere to a magnet. Just out of curiousity who built the motor?
