GM Genuine Parts Camshaft Retainer Plate
Snapped this in behind the front cover of my LS swap, and it fit flawlessly using the new recessed bolts (note: older engines require different bolts) . Includes a factory orange O-ring seal that seals the front oil passages cleanly—no leaks, no fuss.

Excellent but… Get the correct bolts
I searched and couldn’t find a replacement without countersunk bolt holes. This one is a quality replacement part but needs the correct tapered bolts.

Perfect part delivered fast
Replaced mine while doing a cam swap. I highly recommend doing so as my factory seal was shot and could cause an undetectable internal oil leak.
