If so, then if you have a manual transmission it's better done sooner than later as you don't want the clutch ruined from motor oil contamination if it turns out to be the rear main.

I wonder if there's a threaded blanking plug at the back of the block?
Perhaps there's one at the end of an oil gallery where it's leaking at the thread because it has come loose?
It's also a possibility.

Then either way the engine has to come out for a better look/fix anyway.
Can you do the work yourself?
Psych yourself up.
Good luck.

Keep the rubber side down.


It's an auto trans, so it's all sealed up. This is a known issue on this type of truck.

Great.
Then it's a little more straight forward.

I can barely fit a finger between let alone reach far in enough to competently apply a bead of sealant.


Time to grab the can of Great Stuff
