Oil level light/smoke from radiator overfill/sludge in same

Oil level light has come on upon starting each time even since having generic sensor and then factory sensor installed, even though oil pressure seems ok (15 on idle, avg 50 in cold weather, I change oil before time, mechanic changed oil with 20-50) since second replacement. Also, radiator dumped all fluid while at mechanic 6 mo. ago, new radiator and flush. Now this week have smoke from overfill and yesterday started to run hot. Nice guy at Auto Zone checked overfill and much sludge. Please immediate and long-term possible solutions

    I also have a low oil pressure at idle when engine is hot...intermittent. Periodically it seems my engine coolent disapears. I have never seen any trace in the driveway and have checked the level peroidically. Its not a slow simply must purge from time to time and require about 2 liters to top back up. Never any sign of coolent in the oil or on the engine block anywhere. No sign in the exhaust either. I have also had a cracked side tank on my rad and had the side tank replaced (400 bucks) and rad flushed while out.

    Check the oil. Does it look white and milky? Is your tail pipe putting out white smoke?

If oil is Clean and there is no White Smoke that Disapates Fast, Check for Transmission Cooler (IN RADIATER) Problem

What happens when you overfill engine with oil

Depends upon how much you overfill it. Normally an extra half-quart is no big deal. You'll see it show overfull on the dipstick after you run the engine and then recheck it, but no harm done. Add more than a quart extra and you can get what is known as foaming. The oil in the pan will be churned up by the crank shaft and become aerated. This can reduce oil pressure, lubrication quality, and flow rate. Engine damage can result from this.

Check engine light is on. Engine sounds like it's knocking. And oil light is coming on. This 2008 Dodge Dakota has only 63,000 miles.

Sometimes that light means overfill oil
Sometimes after changing oil if they put too much that happens
Check the oil level on cold in level place (give it like an hour or so) for the light to reset
If after that the light still on take it to a tech.

Good luck

What is the problem the vw caravelle starts and have black smoke that comes form the exhuase and dont ideal

I feel its very probable that the cam belt is not timed as accurately as it should be .. this will certainly cause all that you mention - ie, starting troubles - smoke on occasion especially when its struggling to start and also, the starting in limp mode....or, if its not true limp mode... missing / poor running ... ( it wont be true limp mode if there is no engine light / fault codes )
So - the timing / timing belt really has to be checked first ..and put right / go from there..
You will get oil in the pipe you mention - thats long as its not absolutely swimming in it - it shouldn't be awash - but there will be some...
Just check the oil level with the dipstick though - Its imperative that its not even a smidgen above the high mark... if it is - it can cause severe engine damage... it would need to be drained off some. Ideally the oil level should be just below the top mark. Even a slight overfill will cause smoke too.
After the above - I will just mention, this engine does suffer with faulty ECT sensor... This when failing, will also cause poor starting and smoke and missing...
You could if you wish , try that first - fit a new one. Again - its a very common fault on these... The sensors are only about $30 and changed in mins. It is possible that this sensor has failed with all the work thats gone on.. So do bear that in mind also... These sensors wont always set a fault code neither when they go down.
Hope helps.

Can the Dodge dealer check the oil pump pressure? Engine is pecking at idle and is using oil, not smoking. Oil light is not coming on. Any ideas?

Check the oil level, this sounds like an overfill or the wrong weight oil used. It could even be a clogged oil filter, it could even be double staked oil filter "O" rings, one old oil gasket stuck to the engine, then the new filter installed over it.

If you just had the engine oil changed take it back and have them check it, if you did it yourself check it again.

I'm not sure about "pecking" ? taping?

Make sure you have oil, the right oil and not overfilled oil.

Other then that it could be an engine issue that would be hard to check over the net.

Good luck, hope this helps.

Overfilled engine oil on a 2003 porsche 911 smoke comes out of exhaust--HEAVY Smoke.I drained engine oil again(along with the turbo)put in 9.25 qts of oil,still having heavy smoke.

The oil was overfilled this could cause a large amount of oil to enter the exaust and possibly the intake depending on crank case ventilation conditions. If you are positive engine oil levels are adjusted perfectly(warm engine check level running for dry sump oil level ect.). Time is needed to burn off oil residue in exhaust system and intake. Warm up engine low rpm no load, drive vehicle slow with little boost over 5 mins slowly raise rpms for another 5 mins keep driving smoke will burn off while making other drivers mad. sorry just smile and wave.
The engine oil on this vehicle should only be changed by an experinced tech.

Engine light comes on and says engine overheating

Could be three things: Hopefully the first...
1. radiator fan not blowing. (most likely)
2. Radiator clogged (not likely)
3. Head gasket blown... (very possible)

If #1, system cannot detect fan not blowing. It may be the fuse or the relay switch, disconnecetd wire at fan, or burned-out fan motor.
If #2, Flush radiator
If #3, you will see WHITE smoke out the tailpipe and excessive water drops.
Your new oil will have a "milky" look (check the oil dipstick). That is water.
When engine is COLD, remove radiator cap and start car. You will notice high-pressure "bubbles" squirt out of the radiator, even before the engine warms up.

I hope it is #1. and that this is helpful.

Vilvo s40 serviced in june; engine oil warning

most definitely the cylinder head gasket is gone.the oil does not just disappear,it finds its way to the radiator,i.e. mixes with the water.unplug the rediator cap with care(when the engine is cold)and u will see some kind of sludge,creamy colour,which confirms that the cylinder head gasket is burnt.u need an engineer to do the job for u.

I own a 1999 Toyota Solara and the check ingine light is on. I have a n ODB code reader and it reads the code #P0135 heated oxygen senser circiut malfunctoin (bank 1, senser 1) I changed the oxygen senser...

Changing the O2 sensor for a P-0135? Use a TOYOTA sensor. The aftermarket/generic sensors do NOT work in Toyotas.

User with the smoking problem: Remove the valve cover & check for engine oil sludge where the cams ride. If it is sludged, a rebuild is necessary, BUT, Toyota DOES have warranty assistance for this issue. All you need are oil change receipts.
