    Well, check the PCV valve, but probably not there.. What color is the smoke? if blue, means oil, if white, means coolant. Are you consuming oil, (miles per quart?), or water? What does the oil overfill look like, normal oil or discolored, frothy, foamy? You need to determine if you are actually hearing valve rattle, or engine detonation. Valves would typically clatter even when let off of throttle. Detonation would stop immediately on throttle release. How long is engine rough? any smoke or other noises during idling, after this event?

    Smoke appears to be white then a blue tint.
    I am not consuming oil as amatter of fact I check the dip stick ,and it is as if three quarts of oil were added to it.I mean it is way above the fill line. It is Detonation and not valve according to your description.

    At top of steep hill I can cut the engine off and it will start right back up and run smooth I can drive it down the hill and drive all day. or maybe it will run rough and smooth out later. Sometimes
    in the morning a day after the steep hill I get a brief cloud of smoke on start up and that is it except it may run like it is missing
    or fuel filter is bad. I only have to go up the hill twice a week .

    This week I have walked up and down that steep road because I do not want to damage my only source of transport.Most of my friends my age could not walk it and I just barely can.

    Why would the oil be so high on my dipstick?

    I have replaced the modulater valve and this morning the PCV Valve

    Any suggestions?

Go to your local auto parts store and look for a chiltons or haynes repair manual for your make and model of car. 2000 daewoo nubria. They might already have one open and available for your reference, otherwise its probably $20.00 for one. Do a search online in a forum specifically for daewoos. there might be someone else that has this info available.

I dont think it is the PCV but its a good idea to replace the PCV at least once a year either way, and its very cheap, usually $2-$5 at autozone.

SOURCE: When I go up a steep hill, carbon built-up blows out bad from my exhaust

There are a number of things that can cause this condition. First, be sure the engine is properly tuned-up. Have the spark plug and plug wires been replaced? Distributor cap and rotor, fuel filter and oxygen sensor? Then scan PCM (computer) for fault codes. This will tell you if any engine control components have failed. Also check for vacuum leaks or bad vacuum hoses.

Remove and plug the PCV valve hose with bolt to check and see if this is the issue, many times the crankcase is not venting properly and the PCV valve needs replacment it is inexpensive enough just replace the PCV valve located on one of the valve covers it has a hose going to it.

Yes - It should have a plastic grommet type thingy to sit in. Just push in, no threads.
Try to find one in junk yard or order from dealer.. How much could they cost?
You could try an actual grommet.. but must be oil resistant.

I parked my 2004 Ford Taurus on a hill and the low oil pressure light came on and it wouldnt start but when I moved it to the flat surface it started fine . What could cause this?

check engine oil level just on case
if full level ...... not a problem

fuel in tank same thing.... no problem

gravity verses liquid theory
the angle of the hill was too steep
forced oil away from oil pump pickup point in the sump
same with fuel fuel ....pump only on one side of the tank

Why is my 2000 kia sephia blowing blue smoke from the tailpipe. it has 86,000 miles. the check oil warning light is on even though the dipstick reads full.

The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. This is most frequently seen in older or high mileage cars with worn seals and gaskets. It only requires a very small amount of oil leaking into the cylinders to cause excessive blue exhaust smoke.

Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise. An external engine oil leak can drip onto hot engine and exhaust parts causing what appears to be blue exhaust smoke. Other possible causes of blue exhaust smoke include: piston wear, worn valve seals, a dirty or non-functioning PCV valve, worn piston rings, an intake manifold gasket leak, worn engine oil seals and possibly even head gasket failure.

Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. In addition, a reduction in power and oil loss can be indicators that the blue exhaust smoke is caused by an internal engine oil leak. Internal engine oil leaks can also allow fuel to mix with the oil in the crankcase which will degrade the oil and prevent it from adequately protecting the engine.

Operating a car with a severely dirty oil filter, air filter or improperly functioning PCV valve can also sometimes result in engine oil blow-by, oil loss and blue exhaust smoke. Periodically checking the engine oil level with the oil dip stick will indicate if there is excessive oil consumption. Higher viscosity engine oil can sometimes temporarily reduce the amount of blow-by; however, this is not generally recommended. Excessive blue exhaust smoke indicates a possible internal engine oil leak that should be inspected by an ASE certified mechanic.

While driving my dashboard displayed the warning sign for oil. the oil level was correct, but still it is rough on idle and makes a lot of smoke. how may i diagnose the problem?

You have not stated the make and model but i suspect you may have too much oil in the engine ,a common cause for this is the end breaks off the plastic dipstick and it gets filled to about a inch from the bottom of the dipstick ,hence overfilled .

My car keep blowing white smoke them randomly stopping sometimes no smoke and my coolaint is always low down

If youre wondering about a blown head gasket or cracked head, smell your exhaust. If it smells like anti freeze then youre right. If not, you have a coolant leak and your car is burning oil from one reason or another. Check your oil also. Usually when head gasket goes bad you will get water in the oil. The oil will start getting creamy after a while....if it looks like it has water in it, it probably does.

Pouring oil in not sure where it is going

Uses oil ,no leaks

check for a stuck or gummed up PVC valve,it should rattle when you shake it. check for worn piston rings; with someone observing from behind start at bottom of steep hill accelerate quickly from a stop, if worn rings, blue smoke will be seen from the exhaust.

Hi i have 98 camry it blow white smoke not only on 1st start, but only sometimes.driving up hill and it is rattling and blow white smoke and the car have not enough power.pls any help suuggestion is very...

Sounds to me like the head gasket is blown, but there may be sealant in the system which is making it intermittently leak antifreeze into the cylinders.

A bad cylinder head gasket will also cause a compromise in compression, which will cause a lack of power.

Time to overhaul or replace the engine's head gasket, or replace the engine with one that doesn't have a blown head gasket.

Good luck on this repair.

I want to check the engine oil level for previa 2.4 petrol 1995

OIL LEVEL CHECK Every time you stop for fuel, check the engine oil as follows:
  1. Park the vehicle on level ground.
  2. When checking the oil level it is best for the engine to be at operating temperature, although checking the oil immediately after a stopping will lead to a false reading. Wait a few minutes after turning off the engine to allow the oil to drain back into the crankcase.
  3. Open the hood and inspect the level of the engine oil tank. The fluid level on the tank should read between FULL or F and LOW or L.
  4. If the level is below the LOW or L line, remove the cap and add enough engine oil to reach the FULL or F line. Fig. 1: Fill the engine oil tank located under the hood first 90911p07.jpg
  5. Install the oil cap and hand tighten.
  6. After filling the oil tank, remove the engine access hole cover on the drivers side. Fig. 2: Make sure the oil tank is to the F mark 90911p15.jpg Fig. 3: The oil dipstick is located under the driver's side engine access hole cover 90911p83.jpg Fig. 4: Place your finger through the hole and pull straight up to remove 90911p84.jpg
  7. Remove the engine oil dipstick and wipe it clean.
  8. Reinsert the dipstick, push it in as far as it will go, the pull it out and look at the level on the end.
  9. If necessary, insert more oil through the oil filler cap next to the dipstick, this will completely top off the system. Fig. 5: The oil dipstick has two markings for level check 90911p85.jpg Fig. 6: To fill the crankcase, remove the engine oil filler cap 90911p86.jpg prev.gif next.gif

My 2000 Buick Century keeps overheating. We've changed the thermostat and radiator. Any other suggestions

If thermostat is new and you correctly filled radiator by filling while running and let level drop so all fluid goes into block and then fill up radiator again, then you either have faulty temp sensor or plugged exhaust.
