someone tell me why this is:when i start the car white smoke comes out a great deal, smells like anit-freeze. Then my blow off valve has oil leaking out of it, seems to be leaking out of the hoses around there too.

there is no over heating
boost gauge doesnt boost right
no mixtures of oil and coolant when drianed
there is a loose of oil persure
i loose alot of oil over a time limit of about an hour

I have a 89 7mgte auto ct 26 turbo with a bliz blow off valve
was working fine with this set up for a while

i thought it to be the intake gasket can anyone second that?

thats me forgot to login

you may have a bhg or cracked/warped head. as for the oil, it sounds like you have a really bad oil leak if you lose a quart in an hour.

If your exhaust smells like coolant, it very well may be a blown head gasket. The area where the coolant is leaking might be into the compression chamber and thats why your not getting the oil coolant mix, but why your smelling it out the exhaust. Also are sure its coolant your smelling. Could be oil burning off, is it a blueish smoke at all?

Oh an one more thing watch your coolant, see if it keeps going down. If you have to keep adding coolant, that will give you a clue also wether the coolant is leaking into one of the pistons, that and if your not losing it onto the ground.


Sorry about the double post, don't have a clue as to how that happened.

MY COOLANT LEVEL DOESNT GO DOWN TO WHERE IT IS A NOTICEABLE DIFFEREANCE, BUT WHY WOULD I E GETTING OIL COMING OUT OF MY BLOW OFF VALVE? AND IT IS WHITE SMOKE NO BLUE TINT

most likely you just have a little blow by going on... whats the mileage on the engine?

install a catch can so you can relieve the oil that is going thru your intercooler piping and turbo, bov etc

when you get the smoke is this first thing in the morning? how long does it smoke for?

what do you mean the boost gauge doesn't boost right?

look under the car, wipe up all the oil you can see, run the car, get it warm and see if you can see any oil leaking out
try getting someone to just give the car a few revs... just quick ones.. to see if its under pressure it's coming out
what is your oil pressure reading at idle?

The oil coming from your BOV is from your turbo, it is most like time toe rebuild or replace. The white smoke is most likely oil for either your head or rings. Also burning oil isn't always blue. If it is happen after the car has been sitting for a while it IS your valve guides.
