Hello,

I'm new here and I have a 1992 Toyota Paseo. I have had it for about 4 years, and it is the best car I have ever owned by far. It has been extremely reliable, and I drive A LOT! I started to play with the car and put an intake on it, some 17" rims and low profile tires, and I was going to do more. However, circumstances in my business changed and I am now on the road with it quite a bit.

Just lately since it has gotten colder it has developed a smoking problem. It only smokes when first started if it has sat for the night. There is no problem in warmer weather or when the vehicle has been driven already that day. The smoke is light colored, with a possible blue tint to it, and often smells like sulfur. Once it runs for a minute or two and starts warming up, no more smoke. But it can produce a lot of smoke in that period of time.

Does anyone here have any suggestions as to what this might be or how to fix it? Thanks in advance.

the patch? haha just kidding. if its blue like then its your fuel you are running rich if its white then that its a little oil burning. my guess is that your dumping alot of fuel into the cylinders but with that intake causing enough air to cause combustion with out flooding it. check your fuel pump perhaps even replacing it. use seafoam all the way around, give her a couple days of running then see how she runs.

I think I disagree with you Stealth. A bluish tinge suggests it's burning oil. And the smoke on startup suggests the valve seals are worn, so oil drips down the valve seals into the cylinders overnight. This is a fairly common problem with older Tercels (and with the Paseo?).
How much oil does your car use, 92seo?

The cure is to replace your valve seals. There is a way to do this without removing the cylinder head. It involves putting rope down inside your spark plug wells, then turning the engine by hand so the piston pushes the rope up against the valves, to stop the valve falling down when you replace the seals. Or remove the cylinder head. Or, replace the whole cylinder head. Or, just live with it.

There was a thread a few months ago with a link giving detailed instructions on how to do this job.

Thanks for your responses guys.

It is difficult to say exactly how much oil the car uses because some weeks I can drive over 1000 miles while others I may drive a few hundred. I usually have to add a quart every couple of weeks to a month depending on how I drive. It has always been that way though. Nothing has changed recently as far as the oil consumption, at least not that I've noticed.

The only thing that may have changed about what is put into the engine is that I think, although I'm not sure, that the last time I had an oil change they put in synthetic oil instead of the usual 10w40. I didn't ask for it, but I think the guy was trying to be nice to me because my wife cleans for his family. Could the addition of synthetic oil into the picture have caused any problems with the seals?

I bought a can of seafoam this morning and I'll give it a try. Then I think I'll drain all of the oil out from my last change, put a new filter on it, and throw some new oil in there.

If valve seal seepage is my problem, would a heavier weight oil help? I have used Lucas Oil Treatment before in other cars, do you think that might help prevent seepage?

I got some really funny looks today when I started my car in the drive from passers-by. I think they thought my car was on fire.

Yeah, combine a older car that needs a rebuild with extra fuel from a cold start condition and you will get smoke. Rebuild the motor and you will be fine. Get a kit from ebay or better yet, www.importperformanceparts.net

Just rebuild the head (or if you have a tight budget get new Valve stem seals). That should clear up the problem. High Milage Mobil oil and Lucas oil stabalizer is a good temp fix.

no oil burns white to grey and black if alot is burned. gas burns blueish because the octane or O2 and h2o content, to make a long story short...why is the sky blue? because of the O2 and water in the air seen over miles condenced making it blue

I gotta go with NickR on this one. Black - rich fuel. Blue - oil. The morning puffs, (my Camry has it too) - Valve stem seals the most likely culprit

 

[StealthSeo]

okay i stand corrected, not everr one can be trevor wnedsmas

 

[z00y0rk28]

um yea.. i would say the white/bluish is oil - my first engine burned a lot of it.

i never had black smoke...but my car does run a bit on the lean side..

or put compressed air in the cylinder its a hole lot easier that way that is if you have an air compressor.

what can be done if it is running too rich? mine is..it puts little dots of black fuel all over my back bumper...i hate it..what can be done? new fuel pump?

 

[Paseo15psi]

Check your PCV, plugs, and wires. Run some Lucas Oil Fuel System cleaner or a full tank of Premium fuel. If that doesn't clear it up, it may be time to check your O2 sensors and maybe your Cat and EGR.

 

[Kaotickustomz]

im an idiot..whats the EGR?....

 

[Paseo15psi]

Exhaust Gas Recirclulation. It takes some of the exhaust gas and sends it through a charcoal canister to get cleaned up and then reburns the mix. It starts from that metal tube coming from your exhaust manifold back around your engine.

I dont recall seeing that tube...i will look..how do u check and see if thats bad?

Check your DTC's or remove and check the canister.
