Initially I thought it’s sticking (I’m no expert to judge on how smooth it should be), I fished it out with a magnet and it took 3-4 times to remove it, (I posted pictures of the valve) when I put it back it was moving in and out easily.
Unless I’m not doing it correctly ( using a magnet),
First time no oil came out just few drops, second time about 2ltr came gushing out.
