Think I need oil pan gasket

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.

Have the engine steam cleaned (watch any electronics) Run the engine & start looking from the top, down. It may be a bad valve cover leak from the rear of the cover or ck the front & rear seals. (cracked head, block etc. It could be many places

Dear Sir,
Here is the oil leaking Problem Identifying Technique

Engine oil leaks from the valve cover gasket are common.

The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.

External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.

Engine oil leaks at the distributor can be misdiagnosed as leaks from theintake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.

If the oil filter casing shows signs of distortion from excessive oil pressure, theoil pump should be replaced.

Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.

Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

I think it helps to analyse u r Problem

TRANSMISSION FLUID LEAKS,CAN BE FOUND AROUND PAN GASKET.CHECK PAN GASKET,IF IT LOOKS WET AND YOU SEE FLUID DRIPPING AROUND THE EDGE OF OIL PAN, REPLACE PAN GASKET, WHILE YOU REPLACING PAN GASKET REPLACE TRANSMISSION FILTER WHILE OIL PAN OFF.IF TRANSMISSION OIL PAN NOT LEAKING, CHECK TRANSMISSION OIL COOLER LINES GOING INTO RADIATOR YOU WILL LOOSE A LOT OF FLUID THERE ALSO TORQUE SHAFT SEAL WILL CAUSE HEAVY FLUID LEAK WHILE ENGINE RUNNING CHECK OIL COOLER LINES AND LOOK AT THE TORQUE AREA WHILE ENGINE RUNNING YOU WILL SEE FLUID POURING WHILE ENGINE RUNNING THE OIL PUMP PRESSURE WILL PUSH FLUID OUT AT THE LEAKING AREAS.

The Chrysler minivan products all had leaking problems. I have had 5 or 6 different Dodge or Plymouth minivans from 88 to 99. How bad is it. The most common thing is Valve cover leaks. Front and rear seals in the engine leak as well as the oil pan gasket. If its leaking a little bit at a time open the hood and look at the front and rear of the engine. Do you see grease and oil that has gone down the sides of the engine? Do you see a lot of grease on the engine with some clean streaks going through it. You may be able to see where its leaking from. If you know someone that knows what their doing have them change the leaky gasket/s. If not you can probably have it repaired for less than buying another van unless other things are seriously wrong with the van.
Hope this helps... Dale

the manifold gaskets role in an oil leak? oil under the car i would be thinking about a front or rear crankshaft seal or the oil pan, or the oil pressure sender unit. if there is oil on the sides of the engine i would look to the valve cover gaskets.

Are you sure it's leaking out the oil plug ? or is it leaking from the oil filter ? sometimes the gasket to the oil filter sticks to the engine block and it will leak like a heck, let me know what year, make , model, engine size.

Clean all the area and check again; maybe the seal need one new adjust or the oil pan cap too.

Tell us news.

not oil pan but gasket remove oil pan scrape off all old gasket and put on new one the best thin to do is glue it on the oil pan first and let dry with bolt holes in line the glue it to block but this might no be the problem headgasket could leak oil pump gasket valve cover gasket

Its almost impossible to leak antifreeze from oil pan bolts. However if you have a bad head-gasket antifreeze can get into the oil and yeah with that back pressure in the oil pan it can leak. I would look at the water pump first, it is possible that the pump or the seal on the pump is leaking and it is running down the front of the engine and it looks like its coming from the oil pan. Check this vehicle care fully and make sure that it is coming from the oil pan. If it is really coming from the oil pan you would nee more than a gasket you would need a complete head job. Check and let me know, the status. Good Luck
