Question about 1989 Toyota Supra

1 Answer

Blown Head gasket (1989 Toyota Supra Turbo)

I have white smoke/vapor that comes out of my exhaust, and am putting as much coolant into the radiator as gas in the tank. Car is a garaged summertime show car, not my everyday beater. My oil looks normal to me (i.e., doesn't look like a chocolate milkshake color at all). Could it be a blown head gasket...or what else could it be? I suspect the white smoke is vaporized coolant since there is no coolant leaks underneath. I am planning on getting the radiator pressure tested soon, followed by a head-leak test. Any advice to offer? I have received quotes for a head gasket fix for $3000 which has led me to look into the liquid fixes too (like Thermagasket & Steel Seal)..... I am weighing all options at this point, & I'm all ears!

    ....could it be an upper intake manifold gasket gone bad?

  • rryder14 Mar 01, 2009

    Thanks snorkelbobby for your input. I will definitely shop around and get a few quotes at some shops....a $1000 fix is bad, but a lot better than $3000!

    replacing head gasket i use the stock gasket and a eng lift i can hAnd you the oldgasket in less than two hours. because i use aeng. lift to left the head off. you dont have to take the whole thing a part. just disconnect the down pipe and the titdo drain, after removing head bolts lift up a few inchs and thin disconect the eletrical connections. after that lift the head up enough to be abel to clean the head surface and block. let down slow when puting heD back on. slow so you fell it hit the alinement pins . I am sure people will say it will never work. but i have done six supras that way andwork every time. dnt have to take every thing of the head save a lot of time. you lift the head with both manafolds still onthe head.

I think you have a bad head gasket too. It's leaking coolant into the combustion chamber. If you pull out your spark plugs one at a time you will find one plug that is very clean. That's because when the coolant vaporizes, it gets the combustion chamber very hot, thus cleaning the plug.

You must replace the head gasket. I would think you could get it done for $1000.00 at an independant shop. Call around to several shops to get estimates.

If your not overheating or losing coolant, its more than likely engine oil burning. If it is coolant related, possible blown head gasket.

Why would oil be in my coolant?

Oil in coolant, white smoke at start up = blown head gasket or cracked cylinder.

White smoke is water vapor from coolant. Only at startup indicates a small (extremely small) leak -- it will get bigger. Only at startup is because as engine cools it sucks water into cylinder. A compression check will tell you which cylinder is the problem (could be multiple)

I have noticed a whitish /milkish appearance from the engine oil on the oil dip stick what is the meaning of this milkish


Do a compression test and look for symptoms of head gasket problems. If the leak is internal, then the most common cause is a worn head gasket. Water (or coolant) leaks internally through the head gasket reaching the cylinders where it gets vaporized. Symptoms are coolant fluid level going down (with no external leaks), bad performance, loss of compression, overheating, white smoke from exhaust because of vaporized coolant, traces of fuel in coolant reservoir etc.

If there is no head gasket problem and there is no overheating, then the leak is external. Check pump, radiator and coolant lines.

I have a 1992 camry v6, its blowing white smoke when I drive it and it seems to lose power. Could it be the turbo charger?

Actually is sounds more like a blown head gasket or intake gasket. The white smoke is probably water.. and my guess is your coolant reservoir tank is dry or soon will be.. and the next thing will be overheating. The water is getting into the combustion cycle and turning to steam as it blows out the exhaust. Hence white "smoke"..

The loss of compression due to the gasket leak on one or more cylinders would account for the loss of power as well.

I was not aware this model came with turbocharger.. unless an aftermarket one was added.

A good shop will do a compression check and identify if it's the head or intake gasket.

Best of luck!

Somehow the coolant is getting into the exhaust system. Either by a blown head gasket, a cracked head or possibly a cracked block. If it's an aluminum head, that's probably it.

possible blown head gasket. Put in gear with your foot on the brake and rev up to see if there is vapor coming out the exhaust. Also remove radiator cap and run engine to see if bubbles come out of the radiator. Either of these would indicate a blown head gasket or possibly a cracked head.

My Toyota Corolla XL 1996 model is belching heavy white smoke. I have just changed the oil and also the spark plug. What do you think is the problem?

white smoke usually indicates the engine is burning oil or its burning coolant. when the engine is cold remove the radiator cap and start the vehicle, if it immediately begins to blow air and or coolant from the radiator you most likely have a blown head gasket, if not then remove the oil cap and feel for air coming out. if it blows kinda like a hair dryer then you most likely have a piston ring issue and you are burning oil. either way you may be looking at major surgery to repair.

Gas smell in exhaust

you have either a blown head gasket or cracked head. The white smoke is coolant passing through the engine and exhaust. The gas smell is from compression leaking past the gasket or head, pushing fuel vapor into the air.
