Guys,

My car is starting to blow smoke under acceleration (oil) and am about to get the compression checked but i need to know what is & should the compression (psi)be, so I dont get shafted by the mechanic?

What colour is the smoke? Oil is white. To much fuel is black. Compression really depends on the quality of the test gauge being used as I can bet nobody has ever calibrated one. If all cylinders on the tester are within 5-10 psi of each other it shouldn't be to bad for an older motor. If you can change plugs in your car you can do the test yourself its easy.

Well guys,

I have had the compression test and its about 160psi +/- 5 PSI within each cylinder and all appears well with the motor. Now does this mean its the turbo that is making the smoke? is there some sort of seal inside the turbo?

So where abouts is the best place in Melb to get this done, Preferably in the south eastern suburbs and any idea what sort of cost would be involved?

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
