my oil pressure moves with my tach, once warmed up it sits near 0 at idle, and may go up to about 35 or 40 at WOT

Where in the video (time,secs) do you see or hear knock. I don't have an ear or eye for this.

just FYI, I dont hear any knock at all, so if it is knock it is subtle



the wideband display is a $10 volt meter off ebay wired into one of the LC-1 outputs.


The gauge moves ALOT more when the car is cold...

it could be trash in the sender (random flickering) - I had that BUT is it repeatable at the same rpm/load? IOW doesn't only flicker under load at 6k vs. 6k w/o load? That'd be an indicator.

for comparison? I would do it at that same spot, "apples to apples". Doesn't take much to unscrew the OE sender.

The oe spot is the ideal location to measure pressure. And Scot i felt it better to be cautius in my advice as i did see the guage move abit and given the range it showed us there, i figured it was a significant variation to advise him off. Not that he would go around thinking he was 1000000000% safe and be hammering the **** out of his pistons with silent knock.

Magna, I didn't see the gauge wiggle enough to indicate detonation. The OP is very low, though. My '94 is around 85 at cold idle, down to around 30 at normal warm idle, to 25 at hot idle. WOT oil pressure is never lower than 45-50.
