Well... My truck is leaking oil now.

Talk about a major blow. I was over at my friends and we were fixing his truck and I went back in mine, dropped something and then saw a good size puddle of oil beneath my truck. My poor girl and yeah its leaking bad for oil.

I'm pretty sure it happened that day because I didn't notice any the day before, and I was parked in the driveway so it would have been easily noticeable. I did go offroading like 3 days before, but I hardly did anything, just went through one puddle, and it wasn't too shaky.

Soooo.... What do you think? I honestly cannot find where its leaking from but there is a lot of oil on the front side of the transmission. I really hope its just a blow gasket.

 

That sucks man. Is it engine oil or transmission fluid? Coming from the front transmission area sounds like maybe a rear main seal or front transmission pump seal, you should be able to see it mainly leaking from between the transmission and engine if its either one of those.

 

Not enough info provided. Are you sure you didn't park over some one else's oil mess? What to you see under the truck and where is the leak coming from? Year and engine?

 

Definitely between the transmission and engine. And yes is was engine oil, could see from the oil on the ground i needed a oil change anyways

Definitely my oil. I sat down there for 5 minutes and at least 3 drops came off my truck. Thats a good rate for engine oil.

I think its coming from somewhere above the transmission, I was just saying I saw some on it to give a referrence where its leaking.

 

Clean everything up with brake cleaner or engine degreaser, then either wait and see or spray with talc leak detector.

 

Ya man theres not a whole lot on that engine above the transmission that would leak that much oil unless you had one wicked valve cover leak. Its not uncommon for those rear mains to leak. I believe there might also be a breather tube with a breather that sits right about the transmssion. Maybe when going through the puddles its possible it might have gotten glogged up.

 

Thank you sir. I will plan on doing that today.

Thanks for the info man I think i'll try to find out where its leaking from. When I first saw oil I thought for the worst, as in cracked engine block or something similar.

 

Okay so I just checked again and it looks as though its the seal between the transmission and what ever comes next, as in closest side to the engine.

 

rear main is between the back of the engine and the front of the tranny.

 

Yup sounds like a rear main leak man. Glad that i could help a little, good luck and i hope u get it all fixed up.

 

Update: As weird as it sounds... It's not leaking anymore. It definitely was oil when it was leaking and it leaked for a few days. And no its not empty or anything I checked it everyday and its full right now. Its super strange

 

what was your ambient temperature outside when it started leaking?^


I'd do a rear main seal anyways...just a good thing to be done on high mileage.
When I put a new transmission in my truck..I did it..so I didn't have to pull transmission again

 

I heard it would be like like ~$1000 to do though because you had to take pretty much everything out to get it? (engine,transfer case, tranny, driveshaft ect)
