16 detailed photos and 1 video of the actual item — this exact part is what ships.

Noted flaw(s) — photographed above: ASE MASTER MECHANIC TESTING & POST TESTING VISUAL INSPECTION NOTES, ENGINE RUNS GOOD AND IDLE IS NICE AND SMOOTH, WIDE OPEN THROTTLE SNAP SOUNDS GOOD SO PENDING A GOOD COMPRESSION TEST THIS ONE WILL BE A KEEPER! POST TESTING VISUAL INPSECTION NOTES: ENGINE LOOKS GOOD! I DO NOTE SOME OIL WEEP FROM VALVE COVER, OIL PAN & REAR MAIN SEAL SO I HIGHLY RECOMMEND REPLACING THOSE GASKETS AS WELL AS CHECKING OVER NORMAL WEAR ITEMS SUCH AS TIMING CHAINS, GUIDES, TENSIONERS AND ANY OTHER EASY TO SERVICE ITEMS WHILE ENGINE IS OUT AND IT'S EASY TO GET TO BEFORE PUTTING ENGINE BACK INTO SERVICE.
