I have just had my supercharger rebuilt for my 2003 GTX 4-Tec and learned that the original ceramic washers had failed and were missing from the SC, and I was informed that the parts were likely still inside the engine. I have pulled the engine out of the machine and have removed the front oil scavenger assembly and the rear PTO cover to search for washer fragments and inspect the inner parts for damage. There is no obvious damage to any of the housings. I have disassembled the oil pumps as well. This was the first time I have tackled a job like this, so it was quite the learning experience. I'll post my notes and pictures once I get everything put back together.
Now, my question for those with experience in this area. I haven't come across any chunks of washers and the front and back screens didn't have much in them. Should I have expected to find fragments, or would they have likely been mashed up by the oil pump? The oil filter itself has a fair amount of fine grit in the folds of the filter, but no real chunks. I am not sure what more I should be doing to locate fragments. In some other posts, I saw comments about splitting the motor to more fully clean things out, but is that really what is needed? Does anyone have guidance on how else to flush/rinse any fragments that may be lingering about?
I have also attached a picture of the rear oil pump cover and of the pump rotor assembly. You can see some scarring on the surface of both parts, but I don't really know what should be considered bad enough to replace. Any experienced advice would be appreciated. Right now, I am planning to replace these parts but I'd be interested in hearing from others.

The front pump cover and rotor assembly has some very slight scratches on the surface of the parts, but no real scarring. I don't plan to replace those parts, aside from a new gasket.
All in all, I am looking for some guidance from forum members who have done this type of job before. Any insight is most appreciated. Thank you all.
