    Anybody ever come up with a product to repair rusted out oil pans?
    My Big Red Drain's 351 has 2 pin holes right at the bottom corners of the pan ( Of Course ! )
    The trucks going to be retired after I move my disabled Brother and his 2 garages of stuff. I need to haul all the mulch my extended family needs too. I am looking at all the fiberglass resin / cloth / mat I have and thinking hummm. There's no way I want to yank the pan off.

    Did the fiberglass/ resin thing on my 88 F150. The pan was leaking pretty severely, I just drained the oil, used brake clean on the outside of the pan and let it rip. after it was dry, i refilled the oil. I was hoping it would last for a couple of weeks till I could get a new pan under neath the truck. I bought the pan and kept it in the garage; installed it after the old pan started leaking again almost a year later!

  3. You are not going to believe this

    My 92 bronco 5.0L, had a leak that suddenly got really bad.
    I tried several stick-on remedies without success.
    Desperate,.. I went to a local skilled welder.
    Eddie Boh in Central Lake, MI

    2 hours later -- no more leaks.

    We drained the oil, jacked the truck and blocked it. He layed under the engine and
    rested (?) his head on a log and welded the thin stuff where he could and patched
    places that were too far gone.

    Then we filled the oil level to spec and I drove it 10 miles --getting out an looking for
    drips. (none)
    came back and drained the oil and changed filter with fresh oil.

    This worked 2 years and no leaks.
    $175 was cheap and I am still amazed.

    good luck

    The truck is retired because the rest of it is falling off the frame.

    It aint beat me until the tow truck takes it away!

    I had a Bronco II with the same problem. Body mounts were gone!
    It's too thin to weld and too curved to patch very easily. I can weld and have all kinds of sizes of sticks. But with the rust I would be chasing the bead all over and still have a leak. Plus the weld pops would be outrages! I went and bought some fiberglass resin that's like bondo. You spread it on wax paper, put down a piece of fiberglass mat then cover it with more resin. Paste it on and smooth it out. Peal the wax paper off after it cures. I have used it for body repairs and it works real well. I don't know if it can take the heat.

    I had a leak on an oil pan in a car once, put some gas & oil resistant sealant on it. Never leaked again! Orange Permatex, or something like that.

    Find some one that has a good soldering or tinning iron and knows how to solder.
    It takes a bit of time to clean up the pan and locate all the pinholes but the repair will last you a long time if properly done.

    Did the same thing on my 90 dodge. A year and a half and no more leaks. This is the way I would go. Cheap easy and works good.

    I have had good luck brazing or TIG welding repairs like this. Definitely too thin and rusty for arc welding, you might be able to MIG but it would have to be very thin wire.

    I've heard good things about JB Weld, and I bet the sealer mentioned above would work also, since there's no real pressure. I've had good luck patching things with stuff called "plumber's putty" from the hardware store. It comes in a plastic tube. You cut off what you need and roll it in your hand to mix its two parts together. It's pretty rugged when it hardens. I've used it on gas tank pinholes.

    I just changed the pan in my shop took about 2 hours and the pan was about 80 bucks I did have to jack the motor up some and drop the oil pump.
    Before I did that I did do a temp repair the pan was leaking bad I got the truck nice and warmed up then steel brushed the pan and then used brake cleaner and dried it and put a skim coat of silacone sealer not a drop leaked out until I changed the pan good luck

    Ive done the JB Weld thing. Just grind the pan down to bare metal and mix it up like bondo. I did the whole pan and it looked great and worked also.

    I fixed it with the fiberglass resin and fiberglass mat. Put the torpedo heater aimed at the pan to heat it up. Even did the gas tank. All for $12 in materials and I still have half a can left. Our 3-5 inches of promised snow Friday night ended up 1 1/2 inches that was gone by 2 PM.

    Hole in 1997 Dodge Dakota Oil Pan

    My father owns a 1997 Dodge Dakota extended cab. He keeps it in good condition, with regular tune-ups, oil changes, etc. Two years ago, the oil pan got a hole in the bottom. He sealed it with JB Weld.

    The hole just reappeared. He has spent the past two days under the truck, trying to clean it out, scrub it out, and re-seal it. He tried JB Weld again (twice); it failed to hold. He tried to put in a bolt and seal around that; the threads stripped. The local car-fixer place (I don't know where exactly he went) wants $90 for a new oil pan, and $300 to pull the engine in order to get 'at' the oil pan to replace it.

    Any suggestions would be very welcome, as he is getting more frustrated by the minute. He is not a computer person, so I offered to seek an online answer for him. However, Google has failed miserably in the task of assisting me.

    Thank you!
