How to clean and degrease a car engine?

I have a collector's item car, 1990 ... the engine needs to be cleaned. What is the best way to do this myself? OR WOULD IT BE BEST TO TAKE IT IN AND HAVE A PRO DO IT? From what I'm reading this sort of thing can be "if-y".

    it is quite a therapeutic job , just take your time brushing it on ( like painting a door ) ..let it sit a few minutes then wash it off ? do you have a power washer ? or a garage near you that have them ... put the gunk on and drive there to wash it off.

Have ready

  • a garden hose with a high pressure nozzle attached.
  • A full can of Engine cleaner / degreaser
    • Or...Simple green
    • Or similar grease cutting cleaner
  • Wrap with a towel, the distributor cap (all the spark plug wires go there)
    • Then cover really well with Aluminum foil.
    • And if feeling like you want to over do it, place a plastic grocery bag over that.
  • Do the same with the coil, (that's the thing that the 'Center' wire from the Distributor cap, goes to, so follow that center wire from the distributor cap and will lead you to the coil)
Warm engine to driving temperature first.
Now start spraying that stuff over everything you want cleaned. Spray on heavily and NOT sparingly! You may need a second can if really grimy.
Wait at least 20 minutes to allow penetra tion.
Then turn on the garden hose and start washing.
Good Luck.

SOURCE: What is the Proper Way to DEGREASE my ENGINE @ Car Wash Degreaser

You should not have any problem if you don't concentrate on the electrical components. What i mean is stay away from them as much as possible, and don't use alot of pressure wear you can blow things off. Myself i do it at home with a can of degreaser and a garden hose, If you do it at a car wash take a can of WD40 with you incase it stalls or wont start after you do it,WD40 displaces moisture, you would be better off doing it in your own driveway if your aloud too. You can wash any part you want. watch your paint on car, some of that degreaser can take off paint.

SOURCE: why is my engine very smoky when accelerating

if its black smoke I would suspect a fuel issue. several things will cause this... need diagnosing. If its white smoke you could havea severe issue and it needs to be diagnosed. If its grey smoke you may have oil entering the cylinders and need it to be looked at. If the car is not in your name yet and you need a smog test its the previous owners responsibliity by law to fix this. You cant change ownership till it passes smog.

SOURCE: What is the best way

Ford Expeditions are known for getting low gas mileage. It is important to be aware of this before you buy one of these. If you have already bought one, though, don't lose heart. There are some things you can do to help your Ford Expedition get better gas mileage. It won't get as good gas mileage as some other vehicles, but you can improve on what you already have.

* Keep your Ford Expedition as empty as possible. The more items you store in your Expedition, the heavier the vehicle becomes. This causes you to use more gas.
* Go the speed limit. If possible, use the cruise control button.
* Increasing and decreasing the speed often causes you to use more gas.
* Use Techron fuel additive. This fuel additive will clean the fuel line, which will help your Ford Expedition run more smoothly and efficiently. Make sure the pressure in your tires is correct. You want your tires to have an equal amount of air in them at all times. Most gas attendants can check the air pressure for you at no charge.
* Use premium gas when at the pump. This will keep your engine clean and improve your overall gas mileage.
* Get a tune-up. Make sure they check all of your fuels and replace your oil every 3,000 miles. Not performing proper maintenance on your Ford Expedition will cause it not to perform up to its capability. If you want the best gas mileage, you have to get the vehicle up to its top performance.

Other tips here:

  1. One of the things many people don't know about the gasoline they buy is how the octane rating, or "grade", of fuel relates to their specific car. If your car does not have a turbo charged or high compression performance engine, then chances are it is designed to run on 87 octane or "regular". Using "Mid Grade" or "Super" just means that you are using a higher octane gas meant for turbo charged and performance vehicles. Though using higher octane fuel wont harm your car, it really doesn't provide any benefit either, so you may as well buy "Regular" and same some cash.
  2. Don't be picky about brand names. Most of the time any group of gas stations in a given area are all supplied by the same fuel supplier. It's all pretty much the same gasoline, so buy it where it's cheapest. Also remember to fill your tank whenever you are in an area where the gas is notably less expensive.
  3. I've personally found that tire pressure makes a huge difference in gas mileage. If your tires are under inflated then your gas mileage is going to suffer. The correct tire inflation should be written on a sticker located in the driver side door jamb along with other information about your vehicle. It should also be listed in the owner's manual. I've found that running the tires about 5psi over specification can improve mileage a bit more but do so at your own risk, and never exceed the maximum pressure written on the side wall of the tire.
  4. The next most important thing is driving habits. Sudden stopping and aggressive acceleration are sure to bring down your MPGs. It might be a good idea to keep an eye on your tachometer to make sure you shift at the lowest RPM possible in a manual and don't go above a certain RPM in an automatic. Also plan your route to avoid traffic and stop lights if it all possible, idling while stopped burns a lot of gas and gets you nowhere. Sometimes the shortest route is not actually the shortest in terms of time and gas burned.
  5. Get a four wheel alignment. If the wheels are not aligned then chances are your car is pulling in one direction or another, causing you to have to compensate by turning the wheel slightly. This compensation will make your power steering work harder, thereby burning more gas. This can also cause premature tire wear, which will also cost you money.
  6. Check to make sure your spark plugs are properly gapped and in good working order. Corroded, damaged or improperly gapped spark plugs can result in a weak spark or even a cylinder miss fire potentially robbing your car of its fuel economy. A visual inspection of the spark plugs will tell you if they are in good working order and gap can be checked with an inexpensive spark plug gapping tool. ("How to" to come)
  7. Check the air filter. Replacing the air filter is one of the cheapest and easiest basic maintenance things you can do on your car, and a dirty one can ruin your gas mileage.
  8. Clean your MAF. Most modern fuel injected cars are equipped with a MAF or "Mass Airflow Sensor". The MAF measures the amount of air coming into the engine and is usually located after the air box on the air intake. The MAF can be cleaned with a specialized "MAF cleaner" which is sold in an aerosol can at most auto parts stores. Cleaning the MAF sensor element is a very simple procedure if you follow the instructions on the back of the can. ("How to" to come.)
  9. Make sure that your brakes are not dragging. If your car seems to rev fine but does not seem to get up to speed as fast as it should a brake could be dragging which can also cost you mpg's. Simply jack each wheel up, one at a time, and see if it spins freely while the parking brake is disengaged and the car is in neutral. Drive wheels should take a bit more effort to spin but ultimately be easy to move. If any wheel seems to be particularly difficult to spin then you may have a dragging brake and you may want to take it to the shop.
  10. Check for vacuum leaks. A vacuum leak can wreck havoc on your gas mileage as well as performance. Finding a vacuum leak can be somewhat difficult but there is a fairly easy method; spray your vacuum lines with carburetor cleaner. If the engine revs higher while you are spraying then that means the carb cleaner has gotten into the line and you know where your leak is. The leak can usually be repaired by replacing the line.
  11. Now that we've discussed how to get better mileage from your vehicle and how not to over pay for gasoline, we need to point out some scams and gimmicks that need to be avoided. Things with names like "Turbonator" and "Tornado" and other devices that are insert into the air intake system of your vehicle and supposedly increase air flow by introducing some sort of spiral effect. These devices not only litter ebay but are also for sale at many reputable auto parts chains and all have one thing in common; they do not work. The same goes for "electric superchargers" and many other devices where the gains seem way to good for the price. Save yourself some money and don't get sucked in by the advertisments.

Hope helps with this. Good luck.

ask the car dealer. I think any car service dealer can tell you which oil to use. They usually have a book with most cars and trucks listed (Autozone) and which type of oil you use depends on your type of driving and where you live. Such as mostly cold, hot, dusty etc.

I cleaned out my engine. unplugged a few sensors, dry cleaned with a degreaser and plugged back all the sensors, but now my check light is constantly on. the car is working perfectly though. I want to...

Disconnect the car's battery for 5 minutes, then reconnect it. This should reset the check light. If the problem still persists you might've installed a sensor incorrectly or corroded one with the degreaser.

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

Oil leaking from top of manual trans leaving spot over night feel at top and very wet. what could it be. thanks steveo

Could be the shifter housing seal if it is transmission oil that it leaks. The easiest way to find the leak is to spray engine degreaser around the entire area (liberally). Let it sit for about 15 minutes then clean off the area with a high pressure water hose and repeat until the area is cleaned off. Degreaser works best when the engine/transmission are WARM but not hot. Never pour water on a hot engine.....EVER!! Let the area dry and inspect it with a flashlight and mirror. After it it overnight, inspect it again...and again and so on. You should be able to pinpoint where it is coming from.

Not a problem but more like a question or opinion...

Don;t pour that on the valve train!They make an internal engine degreaser that you add to the oil the last 100 miles before an oil change to get rid of that sludge.If you have alot of sludge you need to change oil more often.
