Baffle plate, do I need it?

Pulled my oil pan today to fix a minor leak. Should have left it alone, after pulling the front differential, some transmission support structure and major parts of the steering linkage. The baffle plate is separate from the oil pan, and you have to install that first, then the oil take-up, then the drain pan. Not sure how to keep the baffle plate stuck to the bottom of the block with FIPG, then bolt the oil take up in place, then push the \oil pan up with the FIPG and make all that fit nicely. So, do I really need the baffle plate? What's the function? Looks like it might damp out the oil flow returning from the engine to make a "calmer" pool of oil in the pan. Has anyone tried running without the baffle, so that I only have to deal with one FIPG seal interface?

Maybe just what engine your working on.

Maybe a picture

The only baffles I know about are spot welded to the oil pan .

I have never seen a separated one. Unless it was added for some reason .

That would not surprise me

On the 22RE, I always thought that the "oil baffle" that was separate, was actually a "crank scraper"?

I have an LCE one that I bought eons ago (young and dumb - circa 1990s) that I never installed - because it was "one sided" (was sandwiched between the block and the oil pan, but only on one side of the block) and I was like - How the F do I install this without oil leaking EVERYWHERE???

Here's a "better design" one

If this is used in an actual 22RE racing engine, it might make sense...

and yeah - what motor and pics please

1992 3VZ-E, the V6. (Can't believe I didn't include that, like some rookie. After spending 8 hours just to remove the oil pan, the commiserating beer must have been having the desired effect...). The baffle plate is definitely a stock item. My shop manual describes the install process, but I think they're assuming the engine is removed from the vehicle first. There are no openings in the plate for the crank shaft to protrude through, not like the scraper. The baffle has several small openings to let oil flow down to the oil pan below. It covers probably 90% of the underside of the block, sort of like a lid for the oil pan. Maybe I'll attempt a pic if I get time. Right now, I'm thinking I'll have to install the baffle, let it cure over night, then install the pan.

Out of curiosity, what does the scraper do?

Ahh, that explains it. The baffle plate, or windage tray, keeps the oil in the pan from sloshing around while cornering and four wheeling. Otherwise, the pump intake could be exposed to air. Also it keeps the oil from being frothed / aerated by the rotating crank shaft and balances. The scraper actually removes excess oil from the crank features for better performance. Damn, sounds like I need to put it back on.
Thanks for the help, guys.
