I'm wondering how unusual this situation is? My TD motor not only has been leaking excessively from the rear main seal (I believe that's where it is coming from) but has also been leaking some oil around the top of the dipstick tube. Has anyone experienced this?

I'm thinking too much blow-by, when I remove fill cap I get a light vapor blowing upwards and a few very small droplets of oil coming out onto the top of valvecover.

Breather tube is not plugged. Air cleaner does get some oil residue deposited in housing.

The thing that seems odd to me is there has been no significant change in start-up, acceleration, performance, mileage. They are all still good.

Has anybody out there thought about attaching another breather hose to valve cover and either let drip into small container or route back to air cleaner to help motor breath or vent?
