Never take anything mechanical for granted no matter how many times " you've been there and done that...hence my tale of woe.
Last weekend, I installed a just rebuilt 2117 stroker motor in my VS wide body with full flow - remote oil filter. As usual, I leave the oil pressure sender out until after initial cranking of the motor to confirm visual oil flow through the the sender port on the case.
Installed the sender unit and fired off the motor, it ran great for 10 seconds and ..........seized!
It was locked up tight to wear I couldn't turn it with a breaker bar with the plus removed. Tearing the motor down, and after checking for possible causes, we found that only a main bearing behind the crank pulley bad as it got no oil ...zip....nothing.
Luckily, the only damage was said bearing with everything else unscaved so it got new mains and rod bearings.
But this still did not tell the story of "why"...............
Much inspection later and head scratching, I found that the remote oil filter housing had the factory ( EMPI) 1/2 pipe thread nipple screwed too far into the filter housing it blocked the oil hose port. Motor goes back in on Saturday.
