Break-in Goo?
Cleaning out a motor I bought from a member on here and found a good bit of gray/silver sediment in the lower and upper oil pans and for shits I stuck a magnet to it and it is indeed magnetic. Now the motor is built with new ACL bearings, JE pistons, eagle rods and JWT S3 cams and inside is minty with no signs of this sediment, only in the upper and lower pans. The PO said the motor had no more than 8k miles on it and it looks like that is true by the condition of the head/block. The motor sat for a couple months with oil in it while the PO was going though setup changes and was not run. Typical for new motors to have 'break-in sediment/goo'?
