  1. The vacuum kit looks like it should do the job nicely and at least you'll know there is no air left in the system.
    Check also the thermostat is not stuck closed but you should find that out if you can measure the temperatures before and after the stat with an infrared temp gun (very useful tool for many other jobs on a car - misfire, sticking brakes, etc)

    Let us know how you get on with it 

  2. It does sound like turbo bearings have gone and the last thing you want is for the engine to be inducing oil through the turbo - can lead to a runaway engine!

    If they can guarantee their diagnosis of the turbo being defective then unfortunately it's a case of biting the bullet and getting it done
     

     

  3. Hi....welcome to the Club

    I would think there is a small hole in the intercooler or hose/pipe coming from the turbo
    Usually a rubber hose creates a rasping sound but a small hole in any solidly constructed components can emit a whistle.
    Alternatively, it is worth cleaning the turbo and also check for float on the shaft and condition of the compressor as you look into the exposed end of the turbo.

    Try IceBoxAutos for replacement audio system and they are based in Liverpool so not too far away from you

    Liquid Moly is a great product and have used it for years in engines and never had an issue

  4. I would keep an eye on the consumption and it usually reduces when run in but sometimes they were never run in hard enough and the oil passes the rings.
    Had it on motorbikes particularly and once driven hard enough over time the rings tend to bed into the bores a little more.
    Also check to see if there is a heavier weight engine oil recommended for that engine and should be possible to use that in future until it stops using so much

  5. You are correct in most of the procedure but I would put the cap on before the temperature rises too high.
    Once if has had chance to settle down then release the cap when safe to do so (gradually to allow pressure to release and keep clear of the boiling water).
    The level will then drop slightly. Refill to the level and do the same until the level no longer drops.
    Always ensure the cap is tight and never release when hot and with too much pressure behind it.

  6. if the thermostat is failing to open at around 88 degrees centigrade then your supply of stats is not reliable and would shop elsewhere.
    Check also the coolant pressure cap as if this fails then it can lead to lower boiling point in the system
