Another 4k I will have 100k on this set of banjo filter bolts. Then I will inspect & if all is fine. I will leave them out. If I have crap in them. I but new ones in & change them out every 100k.

Update, back is Sept.2011, at 174k, I recheck my banjo filter bolts. After 100k on just Amsoil 0w-30 SSO & Ea oil filters. Both banjo filter bolts was clean. So I remove both filters from the banjo bolts & reinstalled with new washers. There was no shaft play on my original VF-40 turbo.
