Oil Leak.

redneckracer · Mar 10, 2015

Ok ya'll this is my first kick at the can looking for help..
I have a nasty oil leak from the front end. narrowed it down to what i thought was the front main seal. Is it possible that i did that job wrong twice or can the crank be just a touch warped? Any thoughts or idea's before i take it to the shop and shell out big coin.

Cheers.

If its anything like the Cummins engines where the crank gets grooves in it then maybe its leaking around that. They have a fix for that on those trucks i believe where it seals the groove so it doesnt leak. Was your crank grooved?
I'm only guessing but trying to help.

crank is as smooth as a babies bottom.. and ideas are always a starting point.

It should have had a wear ring under the old seal, so crank should not be wore. The new seal should have a wear ring built on to it. Did you use a seal installer tool or just tap it in?
Did you pull the oil pump? And replace the o ring gasket behind the oil pump housing, if not that may be where your leak is coming from.

tapped in the seal.. but replaced the oil pump, so o-ring gasket was pre-installed from Ford.. soo leaning towards probably pouched the seal on install.

Possible you scratched where the seal seats on the outside? I did that on a pinion seal once and took me a couple seals to figure out why it wouldn't stop leaking. Installed another new seal with some RTV where the scratch was and it's been good ever since.

Need to install the seal with the sleeve it comes with, using the correct tool.

Ill investigate the outside for a scratch/ see if the seal was damaged on install and get a seal install tool to do redo the whole thing. Thanks again for all the insight and help gents.

Must use the install tool.

Oil leak corrected... Wear sleeve was driven in too far the first time i did the repair. Sooo ya'll if your doing repairs yourself... watch what your doing... and it can save a trip to the dealership.
