I have a very dirty auto engine. I need an exceptionally good degreaser to apply, "eat up dirt" and hopefully wash/spray away the softened dirt. An industrial product is always best. but I'm not an industry or "specially privileged contractor". Know what I mean???? thanks, les P.

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.
What I do is give it a high pressure wash first to get all the heavy grease first. Don't know the style of your car but all the newer cars don't have a problem with water.Just don't spray directly into the Alternator, After the motor dries from first wash spray on the degreaser and go by the directions. If it's wet it gust gets diluted. Get in there close and expect to get a mouth full of water-grease.Watch you eyes too.
MAF (Mass Air Flow) meter sits in the collar in the air ducting after the air filter/cleaner housing. It has a plastic box on top to which the electrical multi-connector attaches. Disconnect the plug and remove the MAF housing from the ducting. Use electrical cleaning spray only. Carb choke cleaner will be too harsh. Electrical cleaner spray can be got from any electronic retailer such Maplin, RS components or Radio Shack etc. Not only is this an exceptional solvent cleaner it leaves absolutely no residue. Spray the MAF element (foil) and allow everything to dry. Avoid the temptation to touch the element as it can be easily damaged. Only if absolutely necessary should you use a cotton ear bud and rub very gently to help remove stubborn dirt, always use plenty of spray and use a clean tissue beneath the MAF work area to catch drips and assess the degree to which dirt is being 'washed' away. Before reconnecting the MAF check the connecting pins in the plug and corresponding socket for signs of any dirt, a quick squirt with the electrical cleaner should help here too. If there are signs of corrosion rub the connections with some wire wool to ensure a fresh metal to metal contact.
You may have a dirty idle speed control valve, do the procedure below to correct this.
Get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
The best way to go about this without any problems is to start the process when the vehicle is cold. Go to your local auto parts store and pick up a gallon of degreaser called purple power, walmart also stocks this. Mix this concentrate with water 50/50 and spray it on the motor and all dirty spots...let it sit for about four minutes and hose it off with a hgh pressure hose stream.You will love the results. Let it air dry by itself....do not start vehicle until engine is dry, to avoid engine light concerns. get back to me with any questions....thx..jay HOPE I COULD HELP!!!
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.
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.
Wash the engine at the quarter car wash. Get a dye at the auto parts store that is used to find engine leaks. You add it to the oil. It becomes visable under ultra vilolet light. Get a UV light bulb for your drop light ( not much money, probably at the hardware or autoparts store) and check the engine with the light after driving a short way. The leak will be very obvious and if you do this before the leak has had a chance to migrate all over it should lead you to the problem.
