Re: Oil pan replacement
Biggest advice i can think of is to make sure ALL of the old gasket material is removed before installing new pan to keep it from leaking when you install new gasket a thin coat of Form-A-Gasket or similar type silicone on new gasket sure helps out hope this helps

Jack up truck for safety sake put jack stands under frame . remove all engine oil remove all bolts holding oil pan on if their is not enough room to drop pan you may have to remove bolts holding motor mounts and jack up engine. if front end linkage is still in the way remove linkage. pull oil pan out. check gasket that was between block and oil pan if any stuck to block of engine remove with gasket scraper or wire brush or wire wheel on drill.make sure mating surface is clean put new gasket on new oil pan I like to use a high temp sealer on gasket both sides. Put pan with gasket back in place of old oil pan and tighten all bolts. jack engine down ,replace moter mount bolts replace any linkage you took apart. and dont forget to replace engine oil. make sure oil plug is in pan before pouring oil in . before starting engine check that no oil is leaking than start engine and check for any leaks again if all is good your done. if this was helpful please leave good feed back. A good temp fix on a rusted oil pan is JB weld make sure no oil is on pan clean with towel and rubbing alchol .you may have to drain oil first. if it is rusted badly you may have to use a wire brush on a drill to clean the area to patch. if patched properly it may last for years.
Rather than buying new oil pan, if you drain oil, remove oil pan, take it to local welding shop they can most likely weld/patch it. They can not weld it if not taken off ( fire problem) but personally what I would do is search junk yards or you pull it and replace whole oil pan, might be more effective and cheaper in the long run.
you need to replace to be sure dont leak again, just drain oil then remove all pan bolts,them make sure you clean all the old gasket off and replace with new gasket and use a high temp silicone around pan befor replacing. good luck to ya, It's not hard.
FIRST: oil the plug (I know it sounds redundant)
1. breaker bar instead of ratchet wrench (buy one if you dont have one)
2. extension bar on breaker bar handle
If Getting desperate:
1. buy a new oil pan plug
2. use a damaged/rounded extraction socket on a breaker bar.
3. use an extension handle on the breaker bar handle
Be prepared to buy (and install)a new oil pan if the threads on the oil pan are ruined.
Installing a new oil pan is "easy" for experienced mechanics, but
replacing one can be involved for 1st-timers - and you'll usually want to buy (and install) a new oil pan gasket with the new oil pan.
That's everything from breaker bar (your minimum for stuck bolts) to replacing plug and pan (the worst-case scenario).
The problem with welding on the car is that you will NEVER get it clean enough and weld will not hold. Remove pan and clean it, THEN weld it. I usually screw it down to a piece of 3/4" plywood so that it does not warp while welding...also use a wet rag to cool area near weld as you work (at least 3-4 inches from work area)
You can try JB Weld after you get it off. I would not try any chances with an oil pan. If that oil pan pours out all of your oil going down the road you will ruin your engine. If it is cheaper to get it welded you can try that. I can't comment on removing that oil pan. You should be able to jack it up and look at it. If there is nothing in the way that you have to remove like a cross member, it should be a piece of cake. Best thing to do is to buy a manual for that can and decide for yourself it it will be easy for you to do. I am a Chevrolet person myself. I am not up on everything in every new car. I usually buy a book on every car that I get or work on. Sometimes something looks very simple and it turns out to be a big headache. I do not know what year your car is or how the motor sits in it. You could call a garage to be on the safe side. I can not make a call when I can not see it myself. I gave you the answer as to what I would do. Be careful not to strip out the bolts going back on. When you take it off you will be able to see the bottom side of your engine. If it is old you might want to think about doing anything that you can reach like changing the oil pump. Just some advice while you have everything at reach.
Do not take any chances on that oil pan. Good luck. Rate this as a Fixya if this solves your problem.
