Oil pan leak, NOT the filter housing

adamud · 06-13-2011, 03:50 AM

Hey guys, just looking for some input on my situation.

I have an oil/tranny leak. I am 100% positive it is not the oil filter housing. I replaced every component of it, checked multiple times to see if it stop leaking (it did). Now I have a new leak. The upper block is completely dry. The only part of the engine that is oily is the oil pan and transmission.

My two questions are:
1) ~~Is it possible to remove the oil pan from the under side of the car?~~
It looks like Bentley manual says yes it is. Are there any things I should watch out for? Length of procedure?
2) What would cause a leak where the tranny meets the engine? I have never touched that area since I've owned the car. And yes it is ATF fluid on the tranny, not motor oil.

I bet it's the front pump seal. Pretty common for what you're describing. Replace a lot of those at Ford.

Use the nastiest sealer possible when you put it back on, I use 3M trim adhesive on the block side and Permatex on the oil pan side when I do them. Basically the pan is glued on and the bolts line it up

The front pump seal on a automatic transmission is a common fail at age or high mileage. You can our a pint of ATF seal conditioner in to keep it under control for a while. But once they start its usually a downhill slide. A tired torque converter can make it worse as well.

Good Luck!

Funny you say that. I had to replace that on my Ford truck quite a few years back

Mine was a cracked oil pan (at the drain plug) thanks to the ham-handed oil change guy at Valvoline.

When I have to use a oil change place, I stop outside and make the guy come out, then I ask to see their torque wrench for the oil pan bolt and ask what they are torquing it to.

My jeep has all heavy synthetics in the gear boxes and I have to threaten them with death if they touch any drain plug but the motor...

Its just not worth it to me to have them do it...
