6.5 started leaking oil.

ive noticed when i the truck is parked from 5 when i get home from work and coming outside in the morning theres a little spot of oil right under the skid plate. like a size of a quarter. it seems to be a small leak but i wanna fix it anyways. i was thinking maybe the oil cooler lines? hes a picture thats from the hole of the bumper. theres oil everywhere in the picture plus more on the line thats behind the skid plate

On the driver side, there are other possibility in addition to the oil cooler lines, like the high/low pressure power steering lines.

Hey Brandon
Mine looked just like that at one time. I took the lines out of the cooler, cleaned everything and replaced the seals. No more leaks.

 

[brandonb1481]

ill prolly do that tomorrow. do i get the seals at an auto store?

This is going to sound strange, but I took mine out and matched them up with air conditioning o rings (the green ones). Its been more than a year now and still no leaks. Got them from Advance Auto.

Check for rub though on the aluminum hard lines and squishy rubber hoses. A failure can drain the lifeblood fast.

ill have to find the time to do it. seems like alot to find the problem. but you gotta do what you gotta do. cant let my best running truck die from something dumb. prolly be at it tomorrow

X2 on rubbing of hard lines. Caused the death of my GM block.

 

[brandonb1481]

i have a feeling theres two leaks. theres a dry spot in the middle of the oil spots

Brake clean helps clean things up fast and also helps pin point the leak origin.
