SOURCE: 1993 TOYOTA TERCEL 1500cc Valve Seals Replaced now smokes much worse

You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.

SOURCE: 1993 V6 camry engine over heats and check engine light comes on

The thermostat housing is located by grabbing the upper radiator hose, and following it back to the engine block.
The housing that the hose is connected to is the thermostat housing.
Changing the thermostat will fix your problem!

SOURCE: 99 ford running rough

If it's dead in cylinder one then it could be a burt valve to find out for sure all you do is put it up on top dead center of the compression stroke and pull the spark plug out and apply air to that cylinder, You can remove the air cleaner and the radiator cap so that where ever the air comes out thats where your problem is, if it comes out the intake its the intake valve if it's comming out the exhaust pipe its you exhaust valve if it blows bubbles out of the radatior then it's the head gasket, if it comes out of the rocker arm cover then it's the rings.

What would cause 93 chevy c1500 rough idle smells of excess gas at exhaust


Does the truck seem fine when you first start it & then acts up when it reaches operating temp?
That would lead me to look at my oxygen sensor, a bad sensor can cause the truck to run "rich" which would explain the fuel smell in the exhaust.

Hi there:
Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor.

How did the fuel get into the cylinder in the first place? Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer sensor. If black smoke is present, check the engine oil as in the white smoke example to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Call your mechanic and advise him of what you have found.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

2000 pontiac sunfire starts only when gas pedal is held to floor, idles rough and white smoke comming to exhaust changed IAC valve..no change


If you have excessive white smoke coming from the vehicles exhaust, it sounds like your headgasket is failing. Especially having a rough idle too. Check your coolant level, does your exhaust smoke smell sweet, like Antifreeze? If so, the gasket has blown. Hope this helps...

My Mazda starts rough and idles real rough with black smoke and smell of gas after warm runs great


Dear Smoker.......Sounds to a trained ear that this little guy is gonna need a fuel pressure regulator. It is basically dumping an excessive amount of fuel with the black smoke and all and once it gets warmed up it runs a little better cause it's out of the closed loop cycle. Check the fuel pressure regulator...pull the vacuum line off of it and if you can smell gas or see gas drippin out....that regulator is junk!!! The pressure regulator is on the fuel rail on top of the motor by the way...this should cure your woes.....if not..please get back to me... I HOPE I COULD HELP!!!

1990 camry 4cyl 270k miles intermittant rough idle


Sounds like you have an intermittant problem, check all your wirirng, then you can move on to ignition related coil reluctor wheel ( in side the distribitor electronic control module again inside the distribitor. It could also be a fuel system problem do you hear the fuel pump come on when you turn on the key, the fuel pump should cycle until it devlops adequate pressure ( usually 3 - 4 seconds)
