    Is this bad? (Oil In Overflow)

    I pulled up to work and heard bubbling from the overflow. opened the hood and theres oil coming out. After the car cooled off I removed the cap and theres a bunch of thick sludge in there. No coolant. Theres no coolant or foam or cream on the dipstick or oil filler cap so I wonder if its related to that breather thing thats behind the motor. Every time I remove the intake, theres oil in it. Ideas? Thanks guys. Just hoping it will get me home after I put coolant in it.



    ----------

    I just read this in a post here:
    >>The cam cover gaskets can leak and drip oil on the exhaust heatshields and create smoke. This is too expensive to leave to Cadillac. Order the gaskets and have a trusted local garage do the work or DIY. Cleaning the crankcase breather relieves the pressure that blows the oil past the gaskets.<< http://www.cadillacforums.com/forums...ac-catera.html

    I recently (3 weeks ago) changed my valve cover gaskets due to severe oil leaks. I wonder if my crank case ventilation system is cloged. It looked pretty funky but I didnt try cleaning it at the time. It looked like this one: Anybody ever have this happen? Is this a symptom possibly of a crank case breather clog? http://www.omegaowners.com/forum/ind...?topic=90653.0

    Re: Is this bad? (Oil In Overflow)

    all that stuff has nothing to do with the cooling system

    either the oil cooler has busted or your headgasket is busted

    i would not drive the car

    you could render the engine un-repairable

    coolant and oil looks like sludge ... kind of chocolate milky ... plus you may have had some sort of stop leak put in there at some point causing the chunks

    You're 100% correct there. I did have stop leak in there. If I'm lucky and it ends up being the oil cooler. Is there any way to bypass that bastard ?

    Re: Is this bad? (Oil In Overflow)

    not that i know of ... we've done many repairs on the 3.0L for this (and similar problems)

    mostly for saturns ... the cateras don't seem to have this problem as much

    or maybe there's more of the saturns out there on the roads than cateras

    i wish i could be more help but i'm just a parts guy that knows enough about the service side of the business to be dangerous

    Re: Is this bad? (Oil In Overflow)

    well I appreciate the help. Ive hd the cooler out before when I was chasing down a coolant leak and it looked like the newer style that replaced the oem ones. I believe the newer ones have thicker fins. Anyway, I'll tear into it and see what I can figure out. Anyone know if it will have any definite signs that its gone bad when I take it out? Maybe I can run some water through it and see if it leaks. Dont wanna buy a new one only to find out it was the Head gasket after all. Also, Will a coolant flush be enough to get all this oil and sludge out of my cooling system after I replace the cooler?

    Yes but you have to flush the heater core also other people on here are going to rip you an ass if you do it yourself if you cant recover the fluids good luck

    Re: Is this bad? (Oil In Overflow)

    radiator too... the whole coolant system is a horrifying mess now

    i'm thinking headgaskets more likely than oil cooler since that will overheat and/or over-pressurize the system causing the brown puke in your first post

    Re: Is this bad? (Oil In Overflow)

    I'll pull the oil cooler out first since its I'll have to take the intake off either way. If Im lucky and its the oil cooler, after I swap it, can it be driven to a shop for a flush or will it need to be towed? Should be ok to just fill it with water and drive it somewhere close by right? I wouldnt think about blastin that shit down my driveway into the earth. Dont worry about that.

    The hell with the environment, so what if a bit of oil and coolant get on the ground.
