I have received poorly stamped oil cooler adapter gaskets in Felpro ES70016 and CS9354-3 Conversion Gasket Sets purchased from two different vendors, in two diferent states, 6 months apart. Seems must be pretty widespread. Watch out for these. I would not use them because 1) they are ragged and could possibly flake off into your oil and 2) they are oversize for the place that they fit and do not sit flush. Felpro usually makes very good gaskets but these are very poor and are used with our Blazers.

Anyone else noticed these?
