1995 saturn sl1 smoking engine knocking

My car always had smoke from the exhaust on 1st take offs that was whitish. It is now grey/black, even bluish maybe since I changed the oil filter yesterday. Dont have a blown head to my notice, she runs and drives, just rough. Also recently started a rat tat tat and loud knocking like sound from the engine. I usually noticed this kind of noise but less extreme if u ran out of oil, she burns it quickly. Oil is topped off, iv tried all weights that are safe to see if it would ease the noise but I'm afraid it may only be getting worse. I definitely think it COULD be oil related since the knock is SIMILAR but its not exactly the same, its louder and rougher. Also dealing with a crap battery which has added to the poor performance of her but once u get her going she usually opens up like she should for u. Any ideas on what it could be or what would fix this? Or if its a dying or dead motor or..anything?! I'm desperate to get my car going if possible but if not I need i know, I'm a single mama and would need to handle the works ASAP!

95 ford probe car runs ok but blows whitish blue smoke as accelerate

That is probably the head gasket leaking. White smoke is from antifreeze going through the exhaust. The engine compression is pushing the water out of the radiator.

Vectra 2.5 v6 MSD a lot off smoke out exhaust even when warm

Hi Kieth, It would help to know more about your vehicles problem. Is the smoke very dark or is it a bluish grey? Have you noticed heavier fuel consumption or are you using more engine oil than usual? Is the smoke continuous or does it come only during acceleration? Let us know as many details about the fault and the vehicle as possible and in that way we will be able to offer more help. Regards John

1995 SC1 280K oil burner. Kept full. Previously 41 mpg, now 27 mpg over 1 year span. Oil smells like gas and so does the exhaust. Extreme loss of power. Will not idle. Runs rough at lower rpm, but...

If you are keeping the car forever, swap the engine with a rebuilt one. there are many for sale out there.
about $2k for a rebuilt with core credit. if you are really just keeping it for a year or two until the front "frame" collapses, buy a used engine out of a junkyard, look until you find one with less than 100k on it. there are many for sale on eBay but the shipping will kill you and you most likely have junkyards closer to home.

note if you have an SC1 means SOHC so you have to have a SOHC donor vehicle. SC1,SL1, or SW1
the engines were the same 96, 97,98 i believe. but do not get an older engine.

Burning oil but runs very strong with good plugs

Are you sure it's burning the oil? Check your oil pan gasket and valve cover gaskets for leaks. Is the car smoking? (light grayish or white smoke is oil, black or dark bluish is fuel) Could be bad valve seals. Also, main seals can leak oil out onto exhaust parts.

I was always taught that black smoke is unburnt fuel exiting the exhaust and white or bluish smoke is oil blow by engine wear or damage.

What are the symptoms if my car has a bad engine coolant temp sensor it is a 98 saturn sl1

More specifically you will have trouble starting the car. When the ECTS is bad the PCM reads it that the engine is at -40F. This means that it will dump tons of fuel into the engine in order to warm it up. You may also experience rough idling due to the rich fuel mixture and black smoke from the exhaust (which is an indication of running rich, burnt fuel).

Upon starting the 1995 Camry the engine dies. There is also grey smoke coming from the tail pipe. Checked the oil and there is no water in it.

Is it gray, bluish gray, or white? White smoke, during warm weather, indicates that you have a head gasket out and it's vaporizing water, it will look much like it does when you first start it on a cold day. Bluish gray indicates burning oil, which could be bad valve seating, severe engine wear on your piston rings and oil is blowing past them into the combustion chamber. Grey smoke is probably water as well, though it could be contaminated with oil, or the vehicle could be running too rich, getting too much gasoline. But typically this is more of a black smoke than gray.

Hard starting and to much smoke when engine running idle and sometimes fluctuation

Smoke usually there's a problem.... Bluish gray smoke means you're burning oil (could be a number of things like piston rings, valve seals)... White smoke means could mean you're burning transmission fluid, or there's a crack in the gasket or engine block.... Black smoke could mean you need your air filter changed, bad fuel injectors, bad distributor cap, ignition coil... I would guess it's probably black smoke coming out of your exhaust from the sounds of your symptoms...

Grey/Whitish smoke (small amount) rising from rear of engine

Has to be a small oil leak above the exhaust header or pipe...Possibly the rear of the valve cover gasket...because the engine slopes to the rear, oil collects there, and drips off onto the exhaust. (I'm a 30 year retired British Leyland auto tech)
