leak at oil filter 300SD
 

I replaced the lines from the oil filter to the oil cooler about a year ago. Now I have a new drip. It looks like it is coming from between the oil filter housing and the engine. The bolts feel tight. The drip started in cold weather, like single digit f. Is this a common problem? It looks like it might be a booger trying to remove and replace the oil filter housing.

Not the housing but just the gasket. Did you tighten all 5 bolts? That center one can sometimes be hidden by crud.

yes, remove and re-install the oil filter assembly
in order to replace gasket

no I have not found a center bolt, I will get the pressure washer on it as soon as today. there is eechk everywhere. I just had everything all clean not long ago

having a similar problem on my sd oil everywhere.. Time to dirty my hands

My buddy Frank used a wrench and tightened up all the bolts
he did not remove the assembly
it has not leaked for over 6 months
