Hi Joseph, Some vehicles hav two lights for oil, one being oil level and the other being the pressure. The oil pressure light is the most common found on just about all internal combustion engines and I think common on the Nissan. If the oil pressure light is coming on it may be a defective sender switch, or low oil pressure. If when you start the engine when cold, a rattling sound can be heard, better take the vehicle to a workshop and let them advise you of the cost of repair. If the engine is quiet then you likely have a defective switch. Regards John

My car is a Toyota camry 2003 V6 Oil light is up I had to replace 2 rocker cover gasket & found slugde buid up in both covers .Ive cleaned most off sludge out & then removed the oil sump same again...

it indicates worn hydraulic followers , worn main and big end bearings , worn oil pump
The sludge build up is from not changing the oil on a regular basis
every 10,000klms or 5,000miles
short runs and not allowing the engine to get hot enough to boil off the water vapor from the combustion process
When it comes to oils , it is a personal preference and when you understand that oils ( synthetic or otherwise) carry additives to hold water in suspension, add tensile strength to the oil so that it can keep the moving bits separated and not touching, maintain viscosity and lots of other purposes, then you will realize that over a period of time all of those additives get neutralized and the oil is useless(sludge )
there is not an oil on the market that will last 12 months in an engine even though new car manufacturers claim it to be so
so changing the oil regularly means that sae 20w-40 mineral oil is just as good as the very expensive synthetic oils and cost a lot less
I find that using diesel oil ( shell rotella 20w-40 as an example) will keep an engine clean because it has a higher detergent additive to keep diesel engine clean of carbon

Took my car an 08 Hyundai Sonata for an oil change to the dealer and they told us there was sludge in the engine we have been keeping up with oil changes ,is there a defect with the sonata's engin

There are two main causes for sludge, not changing the oil and filter at regular times, and not running the engine long enough to get it hot.
You might want to get a second opinion from a shop other than the dealer. The dealer may have a sales promotion on engine flushes this month.

Oil sludge in 2010 maxima

flushing your engine could only cause more problems as in sludge breaking loose and stopping up oil pick up screen which would cause low oil pressure which could be fatal to any motor only true fix to removing engine sludge would be to completely disassemble engine and clean with high pressure or have cleaned by machine shop in a vat with solvant

95 firebird 3.4 sfi with a oil pump problem

How would sludge in the engine have anything to do with the fuel pump ?
If the oil filter had sludge in it, the engine does too. Including the passage for the oil pressure sensor.
You could try flushing out the engine, but you may have to have it rebuilt.

How to remove sludge build-up from 2000 dodge durango 4.7

Unable to comment on whether or not the diagnosis you have been given is correct or not, though it does sound reasonable, but in terms of getting rid of crankcase sludge, there are TWO issues/options:

1). Sludge inside the valve cover/s is usually a result of: a) sort distance journeys; b) Poor crakcase ventilation.

You may not be able to do much about a)., but the ventilation [b)] you can by making sure all of the tubes connection the crankcase to (usually) the air intake system are completely clear and able to vent the gases created in the crankcase.

Then to cleanse the lower end of the engine of any remaining sludge, which though unlikely, may have collected, the best option is to use a flushing oil. Engine flushing was in vogue back in the 1960's and 1970's when engine design led to a great deal more sludge. I understand that flushing oil is still available and you may wish to try it to see if it helps with the problem you are concerned about. Best method is to follow the manufaturer's instructions (on the can), but if in doubt, run the engine until it's thoroughly warm and then drain off the old oil. Once the sump is empty replace and tighten the drain plug and refill with the flushing oil and run for at least an hour (ideally more) using a range of revs, though never too high. Once done, drain the oil and wait until it's all out. Replace and tighten the drain plug and refill with the standard engine oil, and HOPE it's cured the problem you started with. Best of luck!!!

At 28,066 dealer oil change. At 28,778 dealer flushed engine to remove sludge build up and changed oil. At 30,835 miles inspection, dealer flushed engine to clean out sludge and changed oil. At 34,630...

First dealer was NOT doing you any justice. Next oil change run a can of GUNK engine flush let idle 5-10 mins then change Oil & Filter and use a good oil like Castrol or Valvoline 10w-30. You won't have "supposed" sludge build up.

Oil preasure not constant oil send. unit changed but still not maintaining the once constant 40 psi

Hello, I'm Donnie.
A couple of things come to mind that could cause the issues you're having.

It sounds like you may have some sludge blocking the flow port in the oil pan, there are 2 ways you can try to resolve this;
1. Parts stores carry an oil system flushing product that can flush out sludge and build-up, and has worked well for me in the past.
2. Do it the old fasion way, remove the oil pan and clean, or replace, the filter screen inside and make sure the oil port that allows the motor to get to the top of the engine is not obstructed, ( you can usually use something like a small hose, or wire to slide up in the port to remove any blockage/build-up.

If that doesn't solve your problem, my next best guess would be that your oil pump may be going out.

I hope this helps you.

Engine knocking doesnt need oil

The engines in the Dodges tend to run on the hot side whitch causes sludge to build up in the engine. They also have very small oil passages which sometimes get clogged with sludge. When this happens the rod bearings starve for oil and begin to fail. The knocking starts out light, only detectable at high rpm;s. It gradually gets worse until it reaches a point where you hear it all the time. On some dodges you only hear the knocking after the engine has warmed up. Some say to use oil additives or engine flushes to try and stop the knock. There is no remedy. Once is starts, it will only get worse.If the engine fails and you take it in for warranty, the dealership will find sludge in the motor and say the warranty is no good because you did not maintain the engine and change oil at regular intervals. Dodge is fully aware of the sludge problem and subsequent engine failures in their vehicles. They choose not to address the problem, instead blaming it on the vehicle owners. Good luck. Maybe you will be one the lucky ones that deals with a honest dealership.

The engine oil light illuminates after making a sharp turn or after coming down from highway speeds to slower speeds

Sounds like you've got sludge. The best way to deal with it is to change the oil. Flushing with an oil cleaner is dangerouse but faster. The cause of this isrunning too long without an oil change, engine overheating, and antifreeze leaking into the oil. Lots of really short trips where the oil doesn't reach full operating temperture. Change the oil with a good cheap oil including the filter. Run the car for about a week 200 miles and change the oil again, filter and all. do this again untill when you go to change the oil it's not exactly black solid like the first time you changfed it. Another cause of sludging is the car does'nt warm up fast enough and not hitting the full operating temperture, it could need a new themostat. Overheating can cause problems too. Is the cheak engine light on? If it is you need to research the problems and get them repaired because everyuthing effects everything else.

2004 Dodge Intrepid 2.7 engine, and oil light keeps coming on.

Major issues with the 2.7L motor. design flaw causes oil to hang in the heads and "cook" creating sludge. Sludge builds until the passage to the timing chain is blocked starving the chain and causing near instant failure...this is a "rattling" or Roulette wheel sound. The 2.7L is an "interference" type engine. When the chain breaks or jumps, the cams stop in position thus leaving the valves wherever they may land. The pistons keep on moving though....and kiss whatever valves happen to be open. Bye Bye Motor. Using Synthetic oil EARLY and exclusively cures the sludge issue. Replacing the timing chain and components at interval is crucial...don't wait for it to break or jump!
