Default Light Blue Smoke from the tail pipe

Here's the story. I was driving home the other night and realized the temp gauge kept getting higher and higher. Yes, I know that I should have pulled over and let it cool down before I kept on going, but i had a bit of an emergency. The temp gauge would get to the red section on the gauge and come down a bit, then right back up. It did this for about 10 minutes before I made it home. I finally figured out yesterday that the upper radiator hose simply came loose. I bought new hoses and filled the car with half water half coolant. I started it up and let it idle to normal operating temperature. It did not overheat, but I did notice a very very light blue smoke coming from the tail pipe. I have only several ideas on what happened. Looking for a little insight from the unlimited resources of NASIOC.

If you're lucky you only killed the turbo. The turbo reservoir is the highest point in the coolant system. If you lost some coolant it may have overheated until the seals failed.

fill coolant to top of turbo coolant reservoir..get all the air out of your coolant lines.


also top off oil to full line on dipstick. with the car at idle....after letting it sit running for 10 minutes....rev the motor. if you shoot blue smoke out the tail pipe....in gobs...its your turbo. dont believe everybody when they say its your head gaskets or valve seals.

take your car for a drive...give it hell between 2-3rd gear....big puff of blue smoke?

turbo is dead

a friend of mine said huge plumes of blue smoke were coming out of my tail pipe when i drove in front of him. the smoke was so bad, NOBODY tail gated me.

he claimed it was my head gaskets going.

i bought a blown TD04-L turbo on ebay....and rebuilt it with a turbo rebuild kit. slapped it on the car and a month later, no blue smoke nor loss of engine oil / coolant

dont be fooled because your 02 bugeye is smoking out the tail pipe.

my 02 impreza bugeye has 132000 miles on it and a recent leak down test showed NO signs of head gasket failure.

best thing you can do is find a low milage subaru TD04L turbocharger on ebay for $75-$200 (there are alot!!!)

and take yours off...and slap the new used one on. problem will be solved. if your smoking blue smoke after that...something more severe is wrong.

just my 2 cents

make sure to jack up with a floor jack....lift the rear of the car using the rear differential housing about 1-2 feet so the nose of the car is aimed toward the ground. that will help get your air bubbles out of the coolant line
