    I have a pinhole in my oil pan. Anybody have success with chemical metal/sealer or sticking a screw in it ?

    Use a screw with a bit of ptf thread tape wrapped around it.

    Don't just stick a screw in your sump unless you know where your oil pick up is.

    How did you get a pinhole in it? The only way they can be damaged is from an impact so its very unlikely that there wouldn't cracks around any hole.

    I don't know where the oil pickup is located.

    The sump could have been damaged in a skid in the ice I had a few years ago. Can't see any cracks. It is up the side. The pinhole is at the minimum oil level, so at least the oil doesn't go below the minimum level. As the car is 1999, I don't want to buy a new sump and gasket, and the hassle of getting a good seal.
    Would I need some kind of sealer with the screw ? I don't know if ptf tape would work with the heat and exposure to oil. What type of screw would be best, self tapper, machine screw ?
    Or would chemical metal be better on its own ?

    If it was me, I'd degrease the area very well. Use a die grinder to roughen the surface as a key, and then use some JB weld to seal it.
    If the JB wants to run down then you may need to make a little shelf out of blue-tack or similar to support it while it sets.

    Is it an almera by any chance?

    The sumps on that age almera can actually rust through.

    Fiesta. Might have got a knock or two during the bad winters we had. Maybe rusting at these points.

    I'd go with weld rather than a screw as the screw will widen the hole and might crack it open.

    I tried three of the local motor factors for JB Weld, no joy in the first two. The third one didn't have it, but could get it from the branch in the city if I wanted. I told him what I wanted it for and he recommended RectorSeal epoxy putty EP-200.

    I asked would it be ok for the temperature and oil and he said "This stuff will do a thousand degrees no bother and the JB is a lot dearer and putty would be more suitable for the job". So I bought it and I googled it when I got home and it said it will withstand a contant 500 degrees F (260 C). So I said I would chance it and I prepared the sump and put it on.

    All good so far, had a few drives in it, leak sealed. The putty has stuck to the sump like S**t so far. Hopefully it will last and it wasn't expensive if it doesn't.
