Hey all. I recently picked up this bnr s4 unit online from a guy. Upon arrival, I noticed that there were scratches in the intake side around the intake turbine. At first, I freaked out thinking I got snowed. There was also a little side to side shaft play, nothing too serious but with nothing to compare it to (except for a k04 with 150k miles on it) I have no idea what is ok.
I called BNR and he said some is normal, 25-30/1000s of an inch. The scratches could be “tooling marks” or just wee bits of dirt that got in there through the intake and made scratch marks.
Here are some photos:
Is this acceptable or is this beyond what it should be? The seller offered to take it back, but if I do that then I’ll have to send the HTP intake I got with it back too
. I also uploaded a video of the shaft play back and forth in the attachments. It’s important to note that there is no contact of the blades with the housing when I push back and forth. It is close, but there’s no touching. There is no play forward and backward. What do you think?
