White and black smoke from exaust in 97 eclipse. how to fix it and what could've caused it ive tried checking the oil and stuff but nothing help?

After extensive research I came to the conclusion that TOO much oil is also a main culprit for white smoke out of the exaust. I changed the PVC valve, the breather and the air filter and it's good as new. There are a lot of incorrect answers here... but for the most part, you can hold true to these: Blue smoke is primarily from internal engine wear.

If it's constant when the engine is on, then the rings etc are worn and need to be replaced. If it only is blue when the engine is cold or first started, the rings are worn but not gone completely. You get the oil seeping during the night and it burns off when the car is started in the morning.

Black smoke is a fuel/air mixture suggestion problems with injection or carburation. Cause of black smoke is due to running rich in the fuel air mix. White smoke can and DOES come from coolant burn off in the oil due to a leaking or blown head gasket, cracked head etc. If you aren't sure or you don't know what you're talking about, don't advise.

Wrong advice can be more damaging than the actual problem. White smoke is caused by engine coolant/Antifreeze being processed in the combustion chamber(s) of the engine.....ie burning, melting, frying, whatever....Period....I'll explain further.... This is automotive chemistry 101....Oil of any automotive type burns blue.....too much fuel issues burn black not enough fuel issues burn grey on a cold day you may see what appears to be white smoke from the exhaust that will disappear after the vehicles engine has warmed up to it's normal operating temp.. This is a normal reaction called condensation... condensation is the result of a small amount of water/dew being drawn into the exhaust usually collecting in the muffler and/or the catalytic converter and is caused by our friend mother nature..... like when you see your breath on a cold day...I am a highly experienced ASE certified automotive repair tech. I have over 16 years of diagnostics and repairs to my credit..I have made a very good living in the automotive business by being precise with my diagnostic procedures....I have worked for 3 of the largest rental vehicle companies in the country.... I have diagnosed and repaired an estimated 200 vehicles to date with the white smoke issue... every vehicle that I mentioned had engine coolant/antifreeze entering one of the combustion chambers in the engine... Most of these vehicles had a damaged head gasket(s).. the most common causes of this issue that I have detected over the years are due to improper maintenance of the engine cooling system, severe overheating of the engine, improper tightening of the cylinder head(s) during an engine overhaul,or some other type of repairs that required the head to be removed and also defects in manufacturing of the gasket or the engine... I have seen evidence of careless repair techs that have scratched or cut the surface of a replacement head gasket with either a tool or the cylinder head during the install process.. sometimes it will never cause an issue but it can... I am very careful when dealing with any gaskets but especially head gaskets due to the amount of work involved in replacing one on some vehicles.. bottom line, I'm not fond of doing the job twice so I'm careful the first time... I have seen improper cylinder head or engine block servicing techniques cause failure of the gasket(s) these types of failures are generally caused by improper cleaning of the gasket surface of the engine block and/or the gasket surface of the head.. I have also repaired or replaced cracked heads and in extreme scenarios I have replaced cracked blocks and severely overheated engines with a new or re-manufactured engine due to such severe damage to the internal engine components or block .. There are a mix of correct and incorrect answers to your concerns by the participants that have replied.. I can assure you that almost every well trained tech will answer your questions as I have.. I'm not saying I'm an automotive god, I am just proud of the priceless knowledge that I have acquired...FYI, I'm a graduate of Denver Automotive and Diesel College in Denver Colorado.... DADC is one of only two Automotive Technology colleges in the country with the intense hands-on and classroom teaching practices to properly train a truly, highly skilled automotive/diesel tech who can easily handle any diagnosis and proper repairs of yesteryears and today's automobile technology....White smoke CAN be caused from oil....I have fast-road engined 1987 Golf Mk II.

If I boot it hard on tight corners, roundabouts, etc, it can cause oil surge in the engine and some oil can 'slop' into a cylinder. The James Bond style smokescreen it produces can be very exciting for drivers behind me! Lots of good answers; I just want to see if I can clarify from my experience.

Good mechanics without great diagnostic tools learn to SMELL. "Burning" (yes, technically it's boiling, not burning) Antifreeze smells 100% different than burning OIL. Let your nose be your guide.

The Antifreeze will have a sweet sort of smell--hey--kinda like antifreeze smells, and it will make your eyes tear up and your throat lungs will tell you to get out of that toxic fog right away. Yes, when forming a good question, you need to give GOOD DETAILS. Does it ALWAYS burn white?

Just at startup? Only when hot?
