    What thread is loosed, is it on the plug or on the tank?

    Just replace the plug if it is the one then replace the gasket.

    there are available replacement oversized drain plugs aftermarket. the other option is to take it to a machine shop and rethread to the next npt (national pipe thread) size and use an oversized drain plug matching the new drain plug hole. next time, do not overtorque the drain plug, snug it with a six inch box wrench

    We call it oil pan.
    Madalas nagyayari yan kasi over tighten ng lube boys.
    Tama si Jick you can machine, you can also buy a new or a good surplus.
    Stand by mo na before your next oil change.

    Hello! I had my oil change sa Shell Station lang (first time outside of CASA) and they said that its ok to reuse the drain plug and gasket during the oil change. This is when I ask them diba you should replace the gasket before you screw it back? I'm worried since reading posts here that you should change the gasket every oil change. Will it really result to loose thread down the road or succeeding oil changes?

    For peace of mind, just replace the gasket on your next change oil. For the mean time, check for leaks. it will cause loose thread if it was overtightened and backyard mechanics are notorious for doing that, they don't know the tool called torque wrench and even if they know, the torque settings is not usually written on the manuel.

    It should be single-use only. You might get away with reusing it a couple of times but they're so cheap that there's really no excuse not to replace them every time. A 10-pack from Lazada is just around P200.

    Hinde naman po nag leleak ngayon. Saan po ba mas ok na place for oil change where you can just bring all the parts and just pay for the labor and where the mechanics know what they are doing.

    Backyard mechanics are usually "de pindot" or not automatic when it comes to details as changing gaskets. They follow what they have been taught by experience. Even some CASA mechanics skip on that that is why it is imperative that you "recover" whatever parts they replaced as a proof that they replaced it. On your next PMS, bring your own gasket, gasket-type is brand/engine dependent, they come in flat copper, crush-gasket, copper with felt paper, or nitrile rubber. What car po ba?

    Hi All , I had a flat tire and called online assistance ( 12 am ) to get the spare tire swapped but while jacking-up the dumb mechanic broke the oil drain plug as it seems he kept the jack exactly below the oil drain plug and entire oil has leaked . Now I have a flat tire + a broken drain plug , how best can I get this fixed ? Shall I visit casa or go to any other workshop like Rapide ? Its a 2014 Chevrolet trailblazer very well maintained throughout with CASA , any inputs will help , thanks

    Go to an auto supply. Buy a drain bolt. Remove old drain plug, put new drain plug. Add oil. Problem solved.

    I think it's highly probable that he bent the oil pan kung doon niya na jack yun kotse, tingin ko sira na yun butas ng oil pan

    I’d say, replace the oil pan including the plug. You should at least try to seek compensation from the towing company.

    Any mechanic worth his salt knows that the oil pan cannot bear the weight of the whole front end. It can deform the oil pan or destroy the engine mounts.

    You can put a jack under it (with a block of wood) to lift the engine, but definitely not the whole front end of the vehicle.

    at that un-holy time, perhaps they ordered the lowest-ranking mammal who wasn't even qualified yet to even open your door, to wake up and go assist you.
    after all, it was just supposed to be a flat tire change. heck, i could do that if i had to.

    if you can get a replacement oil pan,
    unless your car is built differently, i think the mekaniko can replace the entire oil pan then and there in your place.
    if under warranty or insurance, ask if it covers such event, and act accordingly.
    i suspect, chevy parts won't be cheap around here.

    in the olden days, oil pans were made of sheet metal. makukuha sa pukpok to bring the deformity out enough, and some welding to seal the rip.
    times have changed.

    we were instructed years ago, that the only weight the oilpan is confidently designed to hold, is the oil. anything else would be a gamble.
    may be true, may be not. but i wouldn't gamble. i wouldn't put a jack under it, even if it looks strong enough.

    good luck, po.

    Don't operate a vehicle if you can't change the tires by yourself, get a chauffeur instead.
