                    From Percy's VXR himself:

                    Quote -

                    vxrs have under piston cooling jets,and so have a higher pressure oil pump to accomodate them.this means they have oil pressure in excess of 100 psi (over 6 bar) when the oil is cool.even the old zlets have oil pressure of near 90psi.yes i have measured this pressure at the turbo.super.


                    the problem is,turbos are only supposed to run with between 2-4 bar (30-60)psi oil pressure.ball bearing turbos are supposed to have less than 2 bar (30psi).which means you are feeding the turbo's with way more oil pressure than they need and the seals are struggling to cope with it.thats why they seem to leak easily.not so much of a problem with the stock exhaust system,as the back pressure in it helps the oil seals.but when you fit a large bore exhaust and reduce the back pressure,it makes it even easier for the oil to get out of the exhaust side seal with its lower pressure.bingo.blue smoke on idle.

                    after many hours of work,testing and machining by me,this caps the max oil pressure the turbo see's to approx 40psi.this is more than enough to lubricate it yet doesnt overpower the seals.which means,you dont get any issues with running big bore exhaust.no smoke on idle with oil forcing its way past the seals.minimal risk of leaks (standard vaux drain isnt the best anyway) and oily smells when driven hard.

                          Like this:

                          1. locate the banjo bolt on the oil feed line on the top of the turbo.



                          2. undo the banjo bolt and remove it from the feedline.





                          one copper washer will come off on the bolt,the other will be under the feed line and must be removed aswell.

                          3. take the oil restrictor and 2 new copper washers out of the bag.



                          4. fit one of the washers under the feedline where you removed the old one from and line it up with the oil gallery.

                          5. fit the oil restrictor into the oil line with the remaining copper washer on the bolt. (there should be a copper washer on either side of the oil line and should be assembled like the example below)



                          6. tighten the bolt.torque spec for the bolt is 12nm,but a good nip with the torx key until the bolt is tight is usually more than enough.

                          7. wipe up any oil spillage from around the oil gallery,then disconnect the coil pack plug.



                          8. crank the engine over for approx 5 seconds to refill the oil line.

                          9. check around the bolt for any oil leaks,if it has leaked,wipe it up and tighten some more,then try it again.if its ok,re-connect the coil pack.

                          10. start the engine,and allow the car to idle for a few minutes,again check for leaks around the bolt and retighten if needed.

                              surely there's no need to remove the washer under the line just to put another one on??? i just left the under one on and replaced the top one along with the bolt.
