: Catera oil residue please need help

01-10-11, 09:30 PM
My Cadillac catera 98 has oil underneath and mostly on top below the vehicle in the housing of the motor oil pan. oil is visible all the time, can be also seen when looking straight down near the dual intake/ serpentine belt. the top of the pan has a great amount of residue. I know for a fact it is not the valve covers, or the oil filter being loose. also cannot be oil cooler lines checked them in the past as well. oil drips on pavement as well, not a whole bunch and not too little. This is a pain because i have no idea where it is coming from, just know that the issue is below the engine. Bolts are tight around the oil pan transmission pan as well. Any help or suggestions are greatly appreciated

Try looking around the oil pressure sending unit and the exhaust manifolds

Try some cleaning with a degreaser then see if you can pinpoint it again!
