Its a common problem on this car as being a mercedes mechanic i probably fix ten a day. its not the pan gasket, i can promise you its not the problem. You should go to a certified mercedes repair shop they will know how to fix it. but ill be nice, its the data cable seal, part number is 203 540 02 53. its the plug located on the right side of the trans above the oil pan. be careful when removing or installing. the little 5mm bolt holding it in is very fragile and if you break it you will thank me for recomending finding a good mercedes repair shop. ps pay someone to fix your benz or buy a ford!

Is there a certain type of gasket or something else when there is a oil leak starting in a 1998 pontiac firefly


clean around the oil pan gasket area well as some oil leaks are actually rocker cover gasket and filter leaks that run down the block and appear as pan leaks.. Check front crankshaft seal as the oil from there also appears as a pan leak

I have fluid leaking from the bottom of the transmission. Could it be a seal, gasket or do I have to replace the transmission?


What vehicle?
What leaks?

There is no reason to replace anything but the
pan gasket or side case drive axle seals, if you have a front
wheel drive transaxle

You have to get under these vehicles & provide
some info.

Having an oil leak at the bottom of my camry, not the oil pan gasket what else could it be.


There are three other area's that can leak, here they are in order of how often they occur
1.Engine Valve cover gasket(s) (2 if V6 engine), oil runs down the engine and drips off the pan.
2.Rear crankshaft seal leaking
3.Front crankshaft seal leaking. Oil is blown back by air pressure while driving and rips off of pan.

If the gasket is on the oil pan you may try tightening the bolt. To tighten pan gaskets you'll need to tighten in steps in a crisscross pattern. Snug a bolt move across the pan snug another bolt. Do this until all bolts are snug. Do not over tighten pan gasket bolts or leaks will occur. Just uniformly snuf.

If it is in fact the oil pan gasket that is leaking, then you would first need to drain out the oil through the oil drain plug and recycle the oil. Then you can remove the oil pan and replace the old gasket with a new one, refill with the proper amount of oil. Then you can run the car and see if it still leaks.

first drain the oil then u need to remove the bolts that fastened the oil pan to the crankcase using a sockrt wrench / clean it with gasoline/ dry it/ put a new gasket or gasket sealant would do tighten it evenly and fill the engine with fresh oil.

Oil leak at the bottom of the oil pan. Still leaking after i tightend the pan bolt. What should i check next, can this cause other problems?


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 the intake 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, the oil 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.

    Slight oil leak appears to be coming from oil sensor


    Replace the Sensor. You should not need to Change the Oil unless it needs it. Just tighten Finger Tight and 1/2 Turn with Wrench too assure no Leaks occur.
