    help im losing oil

    I have a 99 ls1 z28 it leaks a decent amount of oil I cannot figure out what it is I was hoping for maybe some common problems, before I bring it in .I've been under the car but cannot trace it . There's oil everywhere I allways leave a small puddle of oil and the low oil light comes oil every week or two and help would be greatly appreciated

    If you can't find it, it may be the opsu leaking in the back.

    Giving us an approximate leaking point would be helpful. Front, back, Is the oil leaking from the top etc. Rear main seals, Oil pan gasket, oil pressure sending unit as mentioned, maybe a valve cover. Those are some common places. You can find a leak if you don't get the area clean. You must get it decently clean, then start looking.

    yeah, more info needed. Typically oil will blow back so is it from the rear of the engine back or does the front of the engine have oil on it? Is it getting on the manifolds? These guys have offered some good advice of places to look and also that you need to clean all the old oil off (or at least most of it) and drive it once and see where the new oil is.

    I said I would offer but I know better
    It's a bitch but you'll find it I had a tranny leak and the whole passenger side underneath the car was covered in oil. It took me sitting in the car with it running while someone else found the leak for me.
    It is kind of hard to reach in there but see if you can't feel the opsu area with your hands get someone younger to do it.
    Check your coolant while your at it just in case.

    If it comes to op I got your back

    help im losing oil

    Clean the area real good with brake cleaner, Pull the inspection plates and use a flashlight to inspect. Could be, sending unit, oil pan, rear main. Its oil i would say from the color.
