Engine oil leak? Need info plz

Yea i spent a lot of time searching for the leak, replaced valve covers, oil pan, valve cover half moon. Its the rear main seal. Its shitty to get to, i had a shop near by replace mine for a good price.

 

So what's the deal with these rear mains blowing? Is this becoming a known issue or still a one-off?

 

2019 truck, take it to the dealership for warranty repair or documentation, I wouldn't play guess where my leak is on the internet

 

Looks like the rear main seal. Happened to me a few months ago. See link below.

Here ?

 

Looks like dried up mud or some other stain to me.

 

Is this the rear main seal? I suspected that was the leak area

 

Dirt

 

I checked all over underneath for damages bc I don't want toyota to try to pawn this off on me. I am going to Bellevue toyoya, heard they are pretty good w the offroad scene, my truck is lifted and on 33s so I don't wanna be fighting them doing warranty work.

 

Most likely rear main seal. I’ve seen a few leak.

 

Rear main is behind that. It's the seal that seals the end of the crankshaft. Where it mates to the transmission input shaft.

 

Mine is leaking too, but it’s so small that I whipped it down to check if it’s wet again.

 

If its covered under warranty i would get it fixed even if it was a drop

 

Anyone know how long the rear main seal is covered under warranty? I have my appointment in 3 hours so I'll see if that's the problem with mine.

 

I forget but longer than the 36k warranty. Power train is like 6-60k I think.

 

don't wait, even if you get it documented and they don't fix it at this time they cannot deny warranty work on it after the 36k or 60k warranty expires

 

Warranty is 5 years 60k miles for Powertrain

 

No. It's a weep hole at the bottom of the bell housing.

It goes around the crankshaft to seal the block where the end of the crankshaft comes through. About the midline of the bell housing, so up several inches from where you see the leak.

The transmission has to be removed to replace the seal.

A leaking seal has nothing to do with suspension modifications or using the truck off road. The prime 3 reasons are wear, a faulty part, or a poor initial installation.

Your truck should be too new for a wear issue if it's been maintained.

 

Thanks guys you explained it well. I go in on Thurs. I'll let ya know what happen .

 

Just got a ride home from Lyft. They said mine was coming from the gasket around the oil pan. I guess they use some kind of silicone. There going to take it off clean it up and put some new silicone around it. They want it to completely dry before I drive it again so I need to go back and pick it up in the morning.
