1981,
Did you post the sensor replacement procedure? If not, then don't worry about it. I know that it is pretty simple, but I am still wondering if I need to drill-out the internal passage for the oil sensor or does it need just to make contact with the block casting metal. :confused ...then Let me explain...:
I have a Z28 2-bolt main casting block number (which I have checked, but I can't recall the number at this time). I plan to ask my engine builder if it was modified as a 4-bolt mains, but it probably won't matter since my research has shown me that 500 Hp (plus operation below 6,000 rpm) and under is fine for a 2-bolt main. Anyway, the port for the oil sensor is open (the threaded part), but there seems to be a casting plug of some kind inside the hole past the threads. Does the sensor just touches the casting part of the block or is it supposed to be in direct contact with the oil itself. (I should probably be on the other side of this sign ;stupid, but I never removed it from the factory L81 block, and since the new engine build, I can't tell if my engine builder removed something from the original block :confused....:L I guess I cannot explain this issue very well....:help
