L6 Smoking from around turbo after boost

Recommended Posts

My car is running sweet, has a smooth idle, 19vacuum on idle. Boost is good.

I have a little problem with the alternator belt, a pulley looks like its kinda wobbly (i think it may be the viscous fan)

 

Anyway, after going for a boost. You can smell this weird odor, its nothing like exhaust fumes but its very potent. And there is alot of smokey vapor coming up from around the turbo.

 

I have no idea what is it, I have just removed the inlet manifold and then reinstalled it and torqued all bolts up to specs...

 

Help!!

Make sure you check all your fuel lines, turbo oil feed line, and make sure you don't have a coolant leak. You may have an exhaust manifold leak, check the torque on all bolts. (Usually if you have an exhaust manifold leak you will hear a loud sharp ticking like an injector) Keep an eye on your oil levels, make sure you are not blowing it out of the back or your turbo is going bad and causing you to burn oil. That's about all I can think of with little detail given. Goodluck

  • Fuel lines are good and not leaking, I did install a new fuel filter aswell. My man
  • The turbo oil feed line is done up and doesnt appear to be leaking. But the turbo had been off motor and flange for the oil feed line hadnt been done up properly. I didn't realise this until I started it for the 1st time again and i checked under the car for leaks immediately and noticed a oil leak from the turbo. I quickly put a catch can under the drip turned the motor off. I torqued the bolts on the oil feed oil feed up. This oil leak caused my exhaust housing to be covered in oil.
  • Do you mean a coolant leak from the head gasket on the manifold side?
  • I do hear a loud ticking, like my injectors are noisier than they used to be.
  • My exhaust manifold stud on number 1 is non existant, I need to retap or repair the hole. But! It doesnt smell like or look like its leaking from under there.
  • Oh and I took took the inlet manifold off to check for leaks and retorque the bolts while I was at it. There appears to be no leaks between the manifolds or at the head gasket on either side of the motor.

This morning I cleaned the oil off the exhaust housing of the turbo with degreaser. I took it for a blat and it didnt smoke when I stopped. But something smells kind of foul under the bonnet still.

 

I also noticed that there is something up with my waterpump. When the motor is running you can hear (if you listen for it) a bearing or something around the front of the engine, I thought it was the alternator pulley, but it appears to be my water pump. I took the radiator cap off at 60 degrees and the noise stopped! My fan isnt running straight/smooth either, it is wobbly to a max of around 4mm.

I was meaning to check all coolant hoses, not the headgasket. That is pretty obvious it is blown most of the time.. Oil in the radiator, car is overheating, possibly even smoking a bit. Retap the manifold, I've had the threads strip themselves before. As far as the waterpump, there is a weap hole on it that usually starts dripping when it is going bad.
