Has anyone ever done their own upper oil pan change? I recently completed this job, which took me a couple weeks, because of cold weather, and doing it outdoors only when it's above 48°. Now that I'm driving, with no oil light on, the question, "did I do everything right?, still persist in my mind. There were two "O" rings to be placed on the top of the oil filter housing, which is actually the bottom of the engine. These two "O" rings would be placed on the two ports, but will be facing downwards, and I'm very concerned if they actually stayed in place while fitting the upper pan to the engine. My question to anyone with knowledge of the oil cooling system in the gen 2 is, " if either one of these "O" rings were moved out of place while fitting on the upper oil pan, will this not be sufficient cause for the oil light to come on?. Thanks in advance for y'all input and assistance.
Gen 2 enthusiasts.

You may want to put in at least a general location too as emissions laws are different dependent on the locality/state/province/country.

Thanks much for your guidelines, highly appreciated. I did the procedures and hopefully it will be visible to all.

It is. Gen w Siennas had two different engines: 2004-2006 used the 3MZ while the 2007-2008 used the 2GR. I imagine the oil pan R&R procedure are very different between the two.

I'm not too familiar with the different types of engines, but mine is a 2008, AWD Limited.

The people on this board are familiar with the two different types of engines.

I expect few people on this board, maybe no one, has done the upper oil pan R&R you're asking about, so you may not receive any replies. You do have access to the 2nd Gen Sienna 2GR-FE manual?

No need to reply. It's just a link to your van's factory service manual.
