Where is all this copper coming from? Is it normal for this engine? Still breaking-in?

Seems most LSx motors shed copper for a long while. Some might give you grief for a 40 weight, but I would run it in that car just the same.

This is very common for LT1 and LS1-3 engines. High copper readings are common for up to 20K miles.

Even longer than that on some of them. They must use some copper based sealants in their assembly.

Glad to see the OP get that 40w out of there. You sure don't need it. Changing oil way too often also.

The recipe for any of the newer LS motors is the same: use a high quality Xw-30, change by the olm, and run forever!

last year, my LS6 at 14K was still at 83 ppm Copper--not to worry
