Help? Oil Leak....Causes? (1 Viewer)

I have a 2008, with 150,000 miles. Noticed a small leak coming from the passenger side. Appears to be the value cover gasket? True? Thoughts? Thanks much, Mike

Possible, but it could also be the dreaded “cam tower leak”. I’m just not sure if airflow from the fan will push oil up that high if that’s the source.
it is definitely easier to try doing valve cover gaskets first.

I would clean it off, break the bolts loose and re-tighten them and then watch it periodically.

thanks for your thoughts and suggestions!

i would clean the area really well and you'll get a better idea of where the leak is. at 150K miles, the valve cover gaskets are what i would bet on.

If you end up replacing the valve cover gaskets, plan to replace the spark plug tube seals along with the other required oil line gaskets on the valve train. Those are notorious for leaking on the 5.7.
