    Default Mysterious oil drops, HELP

    Hello, my 2006 Altis has for the past 4 months been showing mysterious oil drops under the engine. i used a tissue paper on a cardboard box to see the colour of the oil and it was light brownish. after a month i showed it to two different mechanics they said power steering pump is leaking, i took it to toyota rawal motors they said engine timing seal is leaking and they will open up the whole engine fix the seal with Silicone! and replace the timing belt etc take one day leave car.

    now the funny thing was during this time i had been observing all the oil levels very closely and neither the engine oil or power steering oil had dropped even a mm. i then took it to lahore and back on motorway and again none of the levels moved even a mm and the oil drops actually stopped after the long drive for a few weeks. later i had the engine oil changed afterwards from mineral to semi synthetic and the level stayed still stayed constant. its been 4 months now and all fluid levels are exactly where they should be steering feels just as good engine is its usual so what could be the issue??
    car has only done 56000km and is driven once every 3 months on motorway and once a week around a block. mostly stands

    i was amazed at the double standards of toyota rawal, they claimed the engine oil had been slightly overfilled when in fact the last oil change was performed by them and when i told this to the advisor he immediately retracted his statement and said no oil level is fine,

    another bit information is oil drops are always erratic sometime they wont show up for days and the placement varies mostly it drips in two different areas with a little gap in between

    i have tried to describe the issue best i can

    here are some more pics, oil seems to be dripping somewhere from top on to the oil sump. the underside of the car is clean and no oil streaks while driving, currently i am not bothering with it as all the levels are fine and the car feels just as it was but obviously there is a issue somewhere so would like to know what exactly is causing it.

    we got the car 3 years ago and before that somebody had stupidly sprayed diesel on the undercarriage, could it be diesel layer sort of melting and dripping even after this years especially after a extreme winter and summer temp and the car not being driven

    Does the oil patch on floor appear on the left side i.e. where timing belt, alternator and air conditioner compressor are attached?

    yes the car is auto but transmission is on passenger side and again transmission fluid level is also perfect. No i never spray oil on the undercarriage but when we bought the car three years ago the person before had sprayed oil. from last three years no oil has been sprayed

    yes it appears on that side. i would also like to add another bit of info i remembered the oil started appearing on the ground few days after i pressure washed the under carriage. maybe the pressure washing loosed the oil that had been previously sprayed three years ago?

    Get your undercarriage pressure washed and then check.

    i did do that recently and the area that i can pin point is right at the back of the engine around the power steering pump so i am no wiser.
    if its not reducing any levels and drives just fine should i just keep a periodic check on all the fluids and keep driving on motorway. any harm?

    There is definitely some leakage from somewhere. Quite possible, it is the minor timing seal leakage. This seal may start leaking if oil is over filled or car is driven on extremely long route without stopping or engine seals are wearing out over time. Currently, the leakage appears to be ignorable. Therefore, keep it driving but regularly check the oil levels. And never over fill the engine oil or transmission oil. Slightly lesser oil is better than excessive oil. One thing you can do is get under the car and properly clean the underside. Then after few days of driving, observe again if there are any oil debris underneath.

    okay i will do that. otherwise car has been religiously maintained and never overfilled. i am currently running liqui moly 10w40 one in blue packing. its a high milage oil and says it takes cares of engine seals and makes them elastic. seems to be holding them up well. however there was no oil reduction before oil change i.e running toyota petron plus and now.
    one last question if its starts reducing oil god forbid it is possible that we keep topping up the oil and just not taking it on long route,any harm in that as opposed to opening up the engine.

    i was surprised about the leakage as the car like i said is driven only 56000 and has full service history from day one so should have developed this issue

    by the way i was more inclined towards power steering pump seal leakage. as per my knowledge engine oil dripping should be dark brown in colour and this was quite light brown. and toyota rawal in all my experience with other cars as well has always given wrong diagnosis, two different personal mechanics say its power steering pump leakage

    i did put it on a lift and observed underneath and the power steering pump was covered in oil and oil was dripping from the bottom of the pump on the oil sump and then to the ground. the timing seal is right next to the power steering pump so still confused between them but i really think its power steering oil. maybe the seals dried up because of non usage. the car is only driven once three months otherwise it just stands. when i took it on the motorway and back the leakage actually stopped for good for three weeks otherwise theres a puddle very 4 days

    Timing seal replacement does not require opening the engine. But depending upon the car, mechanics may need to pull the engine out of the engine bay. Trained mechanics should not have problem with that.
    Well, you should keep driving it if you are not quite sure about the exact source of leakage. You can confirm the leakage by changing the engine oil to some other color oil.

    by timing seal in this engine - it is usually meant "timing case gasket" which requires removal of the sump and also the valve cover along with all belt driven parts - then removing the cast and reapplying toyota FIPG, threebond 1208, loctite 5900 etc etc engine sealant.

    The oil seal hammered into it is for the crank pulley only.
