Could a bad oil sump cause oil to leak ? watch

    A few months ago my mechanic friend asked me to jack up my car, I accidentally jacked it from under the oil sump and realized my mistake when oil began pouring out.
    Brian hit out the dent with a hammer or something and put it back on the car, you can't really notice the dent now and can see no oil dripping out of it.

    I notice when I check my oil levels each week that the level seems to be dropping somewhat, I looked under bonnet and around the engine area at the top part that I could see and could not see any leaks but couldn't see completely with stuff in the way.
    I need to have it put on a ramp or jacked up so we can look underneath and inspect the lower half of the engine for leaks but there is no oil dripping on the ground ( but in wet weather you can see trials of multi colored fluid trailing behind the car, probably oil or fuel )


    Do you think that although oil cannot be seen dripping from the sump that the sump may actually still have a leak ?



    thanks all

    The real answer is to put a sheet of big newspaper under the car when its parked up, preferably somewhere dry. Check the paper the next morning for oil drops. Did he put a new gasket on the sump when he bolted it back on?

    hi, thank you very much

    No , he did not put a new gasket on the oil sum despite the sump being very very crumpled after the jack was placed underneath it, I only discovered the other day that oil sumps have gaskets in them after looking on google, some people say not all car's have gaskets in the oil sump ?


    Would a bad gasket in the oil sump cause low oil on dipstick even though I can see no oil dripping from the car ?


    ( but in the rain , there always seems to be a trail of a rainbow color fluid behind the car that I'm guessing could be oil or fuel, can only see it in the rain and am 99 % sure it's from my car as I seem to see it almost everywhere I go in the rain )

    Best thing to do is leave a sheet of paper under the engine overnight and check in the morning. The oil is either leaking out or being burned or even a bit of both.
