How to Diagnose Oil Leak on Mitsubishi Magna Automatic?

First completely clean all the oil and road dirt from the engine and the transmission and surrounding areas, then drive it for about 10 miles and go under and try to see the leak on the clean surfaces.

My eclipse won't start after I degreased it and rinsed with water

This is why some supernatural (intelligent design force) created WD40.

Water Displacement.

If you are old enough... you would remember the dead cars lining the road-way after a decent RAIN Storm.

High voltage systems... particularly like your DISTRIBUTOR hate moisture.

If you are in a hurry... spray down your SPARK-PLUG wires with WD40... use compressed air to blow off all standing water (especially around your SPARK-PLUGs) ... Pop off your distributor cap and sop up EVERY DROP of water from the inside with a clean tissue or paper towel.

If not... open the hood .... disconnect the battery ground terminal, open the distributor (read a few chapters)... and let everything air dry.

Next time you degrease any engine... put plastic wrap all around the DISTRIBUTOR before you start.

Drive safe & Happy motoring!

2003 mazda tribute giving off bad smell and smokes after driving for about 30 minutes.

By bad smell I take it that you are noticing a smell in the car while driving and not from the rear of the car. I'll also assume that the smoke is coming from under the hood and not the tail pipe. Sounds like you have an oil leak around the top of the engine that is dripping onto the exhaust pipe. I recommend that you clean the engine compartment with a good degreaser like Purple Power or Super Clean. Spray the entire engine down, everywhere you can. Let the degreaser sit for 10-15 minutes and rinse off with a strong stream of water. Repeat as necessary until the engine is free of visible grease and oil. Then buy some engine oil UV dye and put that into the engine oil filler. Save some for the power steering pump (about 10th of a bottle is enough). Get some UV Glasses and a light used for detecting air conditioner leaks. Run the car for 15 minutes down the road. Stop and look for the florescent dye trails to find your leak. This is the hardest part of fixing this problem. After the leak is found the repair is usually minor.

How to stop it from leaking oil

Where does it leak from? If you can't tell because oil is everywhere, get a can of engine degreaser, clean the oil, hose it down and then run it for few miles to see where the oil is coming out from. When cleaning the engine with degreaser and water be sure to cover the electronics with some water proof material, like a nylon bag. Once you see the leak, area, please post the question again with more details. thanks

I had oil on my engine so I used an engine degreaser/cleaner to clean it and got a little carried away when I rinsed it with the water. When I started my car it drove for about 100 ft and then died. I was...

most likely you got water problems. the distributor may have water in it. you can choose to take the cap off and dry it yourself now, or just let it set for 5 or 6 hours and it will start again. if that light does'nt go off, take the positive cable off the battery for 5mins and the computer will reset itself. it's happened to the best of us. i hope this helps,,good luck!!

I have a 1999 Jeep Wrangler with the 4.0 liter engine. Was running fine until I decided to clean the engine. After degreasing and rinsing the engine and under hood, I let it idle. It ran for five minutes...

You could have gotten water in the distributor, remove distributor cap and remove as much of the water that you can, then get a can of wd-40 and spray all in there and the inside of the cap, install cap back on, should start up.

Xc70 missfire after slight degrease and water wash down,

It is possible the coil packs were going bad and had a minute crack that wasn't real noticeable until the water was introduced. There is a more "likely" possiblity that one of the plug wires is now "loose" from the coils and was pushed loose by water pressure.

Engine has old oil in many places--cannot see where leak is--how do you properly wash off an engine?

u either rent a pressure washer or buy engine degreaser from the local parts store and use a pressure nozzle on a garden hose, let the degreaser sit for 20 minutes to do its job before washing it off, aviod ignition system components with direct spray.
