View Full Version : Blowing lots of smoke

Was a cold morning so the smoke coming out of the exhaust at idle looked normal, but when I gave it a rev, the smoke was pouring out like a smoke machine.

I know when its cold your bound to see more smoke come out of the exhaust but this was ridicilous.

Oil seems a bit low, so maybe its been chuggling the oil.

What exactly is the problem? some seal gone dodgy I guess.

But fixing something like that prob isnt worth it, maybe dropping in a second hand motor?

are u sure it wasnt just steam......if its your valve stem seals it'd do it all the time regardless whether its warm / cold morning.

The engine was at normal operating temps (neddle half way) when I was reving it and the smoke was blowing out like a freakin disco :bowrofl: (In N)

I pulled out the whole air box the other day giving it a good clean (including filters) and the temp/maf sensor housing.

So unless by cleaning some of the grease of the walls of the air track, it made what grease was left more susceptible to coming off and going through the engine?

I never actually took the car for a drive, I didnt think that having it in D would make a difference, but will give it a go when I get home.

Oil pressure problems, I wouldnt know if I had one. Probably do, its a heap of **** lol

You said in here is how to do the valve stems, do you mean on this forum somewhere?

Ps. i really dont think it was just steam, it was more of a thick white smoke that would should out a coulpe of meters when I reved the car, looked like a flame thrower.

EDIT: Now that I think of it, if it was oil, it should be burning blue, and their were puddles of water inside the tail pipes and on the ground.
How is the water getting in their, and why is it shooting thick clouds, if a car was behind me in traffic they would literally be blinded by the amount of smoke there is.

Thanks again.

Its called condensation. All cars do it some worse that others. White smoke means water and moisture. If it doesnt stop during a decent run you may have a cracked head or head gasket problem. What this means is water is running into a cylinder and comming out through the exhaust. Check your coolant levels. If they are ok i wouldnt worry about it. Its winter time and the last couple of mornings its been really cold here in Melb and mine has been blowing white smoke as well more than it usually does.

Thats true ^^^^, this is just about the oil problem etc. It can't hurt either!


On one of my old cars to solve that problem I just run some Morey's Upper Cyclinder Lubricant through it (this is NZ product, can be bought at places like Autopro etc. not sure about Supercheap). First time you put it in, use a double dose, then by the label. The bottle lasts a long time. There are other brands as well, there's chemtech (or similar spelling) that have a very good diesel conditioner called 'diesel power' but I'm sure I've seen one for petrol as well.

Seems obvious using these additives that it lubricates seals that are worn...

What oil are you using? It may be too thin for you engine seeing its worn, you might need to try a thicker viscosity.

You could try an oil additive, but only really useful with fresh oil. For 1st and second gen Magna's the Penrite HPR15 is always a good choice (its the one Penrite recommends). If yours has oil burning problems, they recommend HPR30.

Penrite oils are high quality, so expect to pay around $29-$32 for 5 litres. Also buy Morey's Oil Stabiliser (or Lucas? but I think the Morey one is better), thats aroud $15 (or thereabouts I think) So add the whole bottle, then top up with the oil. The oil stabiliser as many would be aware keeps a coating n the parts when not running, so its like Castrol Magnatec in a sense except it doesn't keep circulating metal particles around due to the magnetic part of the oil. This help also with the oil side of lubrication and seals etc.

So although you have an outset cost of the oil change with the good oil, oil stabiliser and filter, which you could get 10,000 out of it if you wanted to, but if you're keen on the 5000 thing, then change at say 7000km and use the same stuff. You also have the ongoing cost of the upper cyclinder lubricant but the bottles last a fair bit of mileage, and you could get away with it after a few tankfuls with every second fill. Get some Flashlube 'valve saver fluid' as well, get the big bottles as its much cheaper (like 4 times as much for less than twice the cost kind of thing). Outset cost of the valve saver fluid etc may seem a bit dodgy, but it should save you doing work to your car.

I had this with my old car and it fixed the chronic smoking problem, and its gone about 80,000km (it was sold as a hack car to a cousin) since it started like 7 years ago, and its still going sweet with no smoking. Another person I know with the same problem (only recently) has found the same thing.

Anyway, I hope this helps. If it doesn't help with your oil burning problem and smoking etc. then at least you know... :( but it should and save you the cost of a new motor :) (a reconditioned one which may be crook too)!

Oh yeah, did I mention that you should in theory get better mileage with the above? I did with my old car. Penrite claim slightly better mileage with their oil, oil stabilisers may help with the mileage and the upper cylinder lubricant and valve saving fluid also help a little also. You should also have a nice clean engine on the inside as well!

okai, well its good news then, it was condensation/moisture.

But I dot think you understand the amount it was blowing, if you stood about 3 meters back from the car and I reved the car, you wouldnt be able to see your own hand in front of your face. There is no way I could drive it on the road.

So is it just overnight, water condenses into the exhaust pipe and burns out when the car starts up?

Or does water get into the cylinders some how?

Yes if your reving it will get worse. Best advise is let the car warm up for a few mins. I do, i have a smoke before i take off. By then most of it has burnt of or evaporated. If your worried about a possible headgasket issue get your cooling system pressure tested for now or just keep an eye on your water levels.

lol, i just realised how stupid it all is.
I studied a chem major for a year at rmit i should of known better.

It was a very cold night last night, so over night water would of collected in the exhaust somewhat more then usual.

In the morning, when the car started, the hot air coming out of the exhaust would of been bringing the water out, and since hot air can hold more water then cold air.

The exhaust fumes hit the cold air out side and bang, condensation. Looked like a nightclub.

Suppose I need a drain plug on my exhaust :bowrofl:

Plus testing confirms, no smoke when started car now.

Thats good to hear! What I said before though still holds true for those where its not condensation :)

was your car parked on a down hill slope on a rainy night?

you'd be surprised how much rain can get into an exhaust like that.. it'll be runnin like a smoke machine at a blue light for ages! lol

Or in my case (on my old car (yes, pre magna)), and your neighbours kids put a hose up your exhaust pipe.

mate

VALVE STEM SEALS - DO NOT GET THESE REPLACED AT SUCH PLACES LIKE MITSUBISHI/ANY AUTO FRACNCHISE, FIND A INDEPENDENT MECHANIC TO DO IT

SAVE $$$$$

its in caps so you read it.

Yes the car shoooooots out white smoke when you accelerate, means its burning water instead of oil. It actually is still driveable however I got it replaced the next day.
