    So just now went to go wash my truck and looked underneath to notice a wet spot around the oil pan. Crawled underneath and the entire pan is wet from the seal down. A small drip off the drain plug. Looks as though its spraying out of the gasket under pressure because their is no leak on the driveway or while its sitting turned off, but it sprayed all the way over onto the tranny area.

    Details:
    2009 4.0 with 49,950 miles. Been using Mobile 1 5-w30 since day one of owning the truck brand new. Last oil change was about 2100 miles ago. Did not use a new drain plug seal, just reused the existing one, BUT it doesn't seem to be leaking from there anyways. Looks like way higher up around the gasket.

    Any ideas would be appreciated!

    Its still under 7/70 powertrain (I think that's the terms) but no longer under 3/36 so hopefully this is covered. I also have a 7/100 Extra Care extended warranty but so far they haven't covered shit so that's probably a waste of time.

    I'm sure this isn't a real expensive repair at all, but my concern is what would cause a gasket to go bad so quickly? Less than 50k and its leaking that bad :eek:

    What's more weird is it didnt throw a oil pressure/indicator light. Good luck, makes me question my 2011 with 38k.

    No dash lights or codes at all. Its been running just fine. Like I said no drips on the driveway so who knows how long its been leaking. Gonna check my oil level once it cools off in a bit. Seems pretty odd to me being such a low mile truck that has been taken care of religiously.

    I don't own a Taco anymore.
    You sure it didn't just come from the oil filter catch ring nipple? I know it usually spills onto the lower radiator hose but maybe it made its way down the block?

    It doesn't look like it came from the pan gasket to me.

    1. bought it... 2. Mud flap delete 3. BHLM 4. AUX input on factory stereo 5....... Check the build
    From having removed one before and puttin gon a new gasket... That's cheap easy and takes about an hour to drain the oil, clean everything up, put on new gasket and replace. ( the cleaning and drying takes the longest). Gasket should just be a high temp, liquid style that squeeze a bead onto the pan with before tourquing it back into place.

    If its not under warranty I'd suggest doing it yourself to make sure it's done write, especially sense it's very easy to do.

    As to why its leaking in the first place: probably just factory fluke, it didn't get enough gasket on it or something. Look closely at the mating faces of the pan and bottom of the engine block to make sure there's no like dents or anything in either that could cause a bad seal.

    Rear main seal..

    Check where the motor meets the trans...does it look like the source? Or is it looking like the upper oil pan gasket.. either of the oil pan gasket seals are easy to replace but you have warrenty so that's no problem there. My oil pan has residue all around the gasket and many others too, but your leak is pretty significant

    Also for shits n giggles but not likely with this motor..check the heads at the firewall for oil leaks dripping down..

    That will only happen if low pressure is detected which means in this case low on oil level but OP stated no puddles so its not leaking that bad..unless all of the oil has leaked out :cookiemonster:

    If its the rear main seal that would major suck! Power train warranty should cover it though right?? I hope so. But then they have to drop the tranny... will that cause long term issues for me?

    Long term issues as in not taking care of it? Or getting it replaced?

    First find out exactly what the source is and go from there..

    yep, 60 month or 60,000 powertrain should cover both seals, take it to toyota on their dime.

    Brad's rear main seal is leaking the same way too, but more trans fluid. But he's at 100k.

    Hope that's not the case!

    No issues when done right..its not a complete tear down of the motor or anything like that, only removing the tranny to make room for main seal..replacing the actual seal itself is a two minute job :cookiemonster:

    Well, I guess I'll take it in then. Either seals are gonna require an oil change though, and I doubt they will put synthetic back in, cheap bastards. Will probably charge me more for synthetic :rolleyes:

    We'll see I guess.

    Question still remains, what could have caused this type of damage at such low miles and very little off road use? Something I could have avoided at all :confused:
