I have a 1995 Dodge Avenger. Had minor oil leaks from all engine seals but now it is streaming when at idle. Not leaking when stopped. I had changed the oil and put some Marvel Mystery Oil in - I assume that did something. Did I cause a build up of sludge on oil pump screen, oil filter, or cleared the seals and now they are pouring oil. Good oil pressure and seems to be leaking from passenger front of car - towards the middle of the engine. Before I can get it on a lift, any ideas on what I caused? Thank you.

 

You don't say what motor ... There are different places depending on what motor ..
If you had built up sludge the oil pressure would be low ...Middle of the motor can be a cracked head or head gasket

 

Thanks - it is the 6 cyclinder. Wouldn't a crack head have water going into the oil of oil going into the coolant? The leak seems to be behind the serpentine belt -

 

depends were the crack is it ... also can be valve cover gaskets ect ect ... trying to diagnose with limited info is near imposible ... pics of area might help
