Hey guys I'm new to the community and also new owner of an evo 9 mr, I have this issue of white cloud of smoke coming out of exhaust when shifting. Help please

 

Head gasket failure.

 

Could be a head gasket. What other symptoms do you have? Does it happen when its cold or warm? Really need a little more info

 

could be leaky turbo seals

 

White smoke is actually steam - Oil from turbo seals burns blue/ gray / black. Oem turbos are water cooled but never heard of them failing and allowing coolant to reach the impeller area That would take a crack in the body. Headgasket is the classic cause of white smoke (Steam).

 

i've had white lingering smoke from turbo leaking oil into my downpipe. its more white than grey but yeah it smells like oil.

White Smoke Coming From Exhaust: Explained

• White smoke from your exhaust means coolant is exposed to your engine's combustion process. In most cases, this is the result of a blown head gasket, but a cracked engine block or cylinder head could also be the cause.
• A compression test or cylinder leak-down test may be done to diagnose a blown head gasket, but the appearance of coolant in the oil (as a coolant-tinged foam) or oil in the coolant (as an oily foam) is a dead giveaway.
• A low coolant level and the need to repeatedly refill the coolant is a sign of leakage in the cooling system, and possible head gasket failure. The inexplicable loss of coolant and the appearance of white smoke (steam) in the exhaust go together like hand and glove.
• Besides exhibiting white smoke, another sign of a blown head gasket is that the exhaust will have a sweet smell, like the odor of butterscotch or graham crackers, an artifact of chemicals in the antifreeze being subjected to combustion.
• White smoke in the exhaust (steam) indicates vaporized antifreeze, which will coat and contaminate the car's oxygen sensors and set off the check engine light. Besides replacing a head gasket, you will also need to replace the affected O2 sensors for that bank of cylinders.
• A blown head gasket is most often caused by detonation in the combustion process. This is usually brought on by low fuel octane, oil contamination in the air/fuel charge, or excessive boost or nitrous injection in high-performance engines. It can also be caused by poorly performed repairs, a clogged injector, clogged fuel filter, or a marginally failing fuel pump.

 

I think we need more details. Are you getting white smoke under regular driving conditions and gear shifting or while doing "spirited driving" and how much boost are you running?
In addition to the above posts, you could be lifting the head under boost, if you are running a lot of psi, thus allowing coolant into the combustion chamber....just a thought, but more details on the driving condition is needed.

 

Boost is 14 at idle and 22 to 24 while cruising. Oil seems at a good level. Although coolant needs to be refilled, my car does not have a cathalityc converter

 

Low coolant / white exhaust means head gasket. You don't have 14 psi boost at idle. Maybe 14" water negative at idle.

 

thank you guys it was turbo seals I replaced my turbo it has stopped

 

boom @mitsuatb

 

I will like to appreciate your guys response I’m sorry I didn’t update my car was broke down for a while I just changed the turbo and tuned two weeks ago

 

np man. you would have seen wet oil in the downpipe. now it would just have soot, no liquid

make sure you have a good catch can/pcv solution. those turbo seals wont last long if you have high crankcase pressure
