My 98 Mitsubishi eclipse 2.0 I recently purchased had oil in the spark plug wells I noticed the valve cover bolts were loose (2) u tightened then down changed plugs and wires when I removed cylinder four plug oil build up went into hole spark plug sits in flash engine light came on and flashes when in park took it to auto zone they removed light but it still flashes in park but never stays on codes they pulled before clearing it were cylinder one and four mis fire but I removed wires one by one and started it to check for difference all when pulled shuttered car runs fine drives fine shoykd I be worried if so ways my problem

Remove the valve cover & replace the gaskets

Instructions

1. • 1 Allow the car to cool. Disconnect the battery terminal. Remove the right side vent screen top extension. Disconnect the ignition coil with power transistor and its wiring and brackets.
     
   • 2 Disconnect the left hand side coil wires and spark plug wires. Remove the spark plug wires, valve cover bolts and the valve cover. Unplug the electrical connections from the intake manifold runner control actuator. Unfasten the actuator retaining the screws, right bank heated oxygen sensor front and rear.
     
   • 3 Remove the heated positive crankcase ventilation (PCV) valve. Remove the heated oxygen sensor plug and the Differential Pressure Feedback EGR (DPFE) sensor. Disconnect the ignition coil with power transistor and its wiring and bracket. Remove the valve cover bolts, the valve cover and the old valve cover gasket. Clean the valve cover seating area with automotive engine cleaner and place the new gasket in the gasket seating area.
     
   • 4 Replace the parts that were removed and disconnected by reversing the steps. Replace the valve cover gasket and tighten the bolts, in sequence, ensuring not to over tighten. Put back the ignition coil with power transistor and its wiring and bracket, the heated positive crankcase ventilation (PCV) valve, the heated oxygen sensor plug and the Differential Pressure Feedback EGR (DPFE) sensor.
     
   • 5 Add oil to the car. Start the car and let it run at idle for a while to check for leaks..
     

Assuming you're talking about the lower oil pan...it's very simple

1. Lift at least the passenger front side of the car using a jack, jack-stand, and blocks on the rear wheels

2. Drain the oil out of the pan by removing the drain plug (just like an oil change)

3. Remove all of the bolts on the outside edge of the oil pan (should be about 11)

4. After all of the bolts have been removed the oil pan is free to come off. It might still be stuck on and a few gentle taps with a rubber mallet with knock it loose. Be aware that there is still some oil inside the pan, so this step will be pretty messy

5. Clean the surface of the engine where the oil pan was mounted against

6. Take your new oil pan and place the gasket around the rim of the pan (if not using a gasket then put liquid gasket around the rim. This is important to ensure the pan doesn't leak)

7. Place the oil pan on the engine and bolt it back on. Start by tightening on bolt, then one as close to 180 degrees across from it. Repeat until all the bolts are tightened.

8. Fill the oil pan with new oil. You may also wish to remove and replace the oil filter.

9. If you used liquid gasket, give it a few hours to set (look at contained for a recommend amount of time to wait). If you used a rubber gasket, you don't need to wait.

10. Start the engine and check for leaks. If you notice any oil leaking from around the seal then turn the engine off, go back to step 2 and then repeat from there on. If you don't see any leaks, you are good to go.

Three seals to check. easiest is the valve cover seal. Number and remove the 4 wires going into your spark plugs. remove 4 nuts holding the cover and replace seal.
Next easiest is the distributor O-ring. Remove air filter assembly remove the distributor cap, then the distributor. With the valve cover still off, loosen the 2 bolts that clamp the distributor down. Remove the 2 terminal leads going into the distributor (4 wire terminal/2 wire terminal) Mark the case of the distributor and the case of the head with one line so you can line it back up on reinstallation. remove the 3 bolts holding the distributor down. Replace O-ring. replace distributor, align, tighten the 2 bolts, then tighten the 3 bolts. replace terminal wiring and cap. replace air filter assembly. Replace valve cover with new gasket. Place spark plug wires back into their proper places. The last one is the oil pan gasket. Drain all oil and remove all blots holding the pan. drop the pan and replace the gasket. Put it all back into place. Do not over tighten the pan bolts as this will cause the gasket to deform, making it leak again.

look hard around your valve cover or your spark plugs holes especially #3 and #5. i found mine on 3 and 5 spark plugs. oil sometimes drip down to hot eng and smell like burn oil. possibility your valve cover that seal your spark plug hole is worn out and leak around the valve cover and straight down to hot area. replacing valve cover gasket is not easy and if you take it shop will cost you over $1000.00 because of intake manifold and a lots of hardwares to remove. shop around before you take it to the shop. if you do it your self with a friend make sure you take picture for every lines ,bolts sensor plugs and so on you remove. also may as well tune up or change your spark plugs. good luck

Most likely you have a leaking valve cover gasket. There is a gasket the goes around the valve cover, and also a gasket where the cover mates to the head for the spark plug holes.
