    Default 95 Grand Marquis oil pan rust hole

    Well, I picked up a 1995 Grand Marquis a few months ago to drive over the winter. I purchased it knowing it had a small oil leak, but the leak has got worse over the last month or so (much worse it loses about a quart every 175 miles). I know that it is a pretty big job to replace the oil pan on these cars, so that is probably not going to happen any time soon. I can clearly see where the oil pan has the hole in it so I'm going to attempt to wire brush off the rust, hit it with some brake cleaner, and put some sealant over it. Just wondering if anyone has done this and what sealant they have used? The guy at O'reilly's recomended the orange permatex rtv, but I figured I would ask here first.

    I've heard of people using JB Weld. I cant imagine RTV would hold up, its basically rubber. You want something hard on there.

    That's what I thought too on the RTV. It looks like JB weld it is. Thanks.

    From my experience in repairing the un-repairable I've found that JB Weld is good, BUT it's silly putty compared to PC-7. I wouldn't even consider anything else but PC-7, mixed right that stuff hardens like steel only harder I think!!
    I've never, ever fixed anything with PC-7 and had it not work, permanently!
    Once you've tried PC-7, you'll never go back!

    Having a shop replace the oil-pan will take a day's labour to complete. I had it done on my '93 GM last year. Cost me over $700...

    HAHA Mighty Putty! It says that it fixes leaks instantly, just apply and let dry. I could probably even clean off the oil pan with some orange glow and a shamwow

    Yea I kinda figured it would be big money to have someone do it. I took it to Midas just for the heck of it and they wanted $900. The car is not worth putting that kind of money into it so I'm going to try the JB weld. It can't hurt anything because the pan would still need to be replaced anyway. Even if it doesn't totally stop the leak, Ill just continue to leave a sheet of plywood on the driveway to keep it clean, and just keep dumping oil in it every time I get gas until I find somewhere cheap to get it replaced. $900 can buy an awful lot of oil.

    It has been a couple of weeks since I put the JB weld on the oil pan, and I am happy to say that it totally stopped the leak. I used a product by JB weld called JB Stik. I thought that regular JB weld might want to sag and drip off once applied to the oil pan, so I found this JB stik that is like a putty. You kneed it together and flatten it like a pancake and push it on. I wire wheeled the pan, cleaned it with some brake cleaner, pushed the JB Stik on, and let it dry a few hours and the leak is fixed. Thanks for the advice!

    quick steel at walmart is also good.. i suggest everyone buy a stick and put it in the glovebox.
