Had a rego inspection, failed, told that there is an oil leek query top and bottom and that the bushes in the lower L & R had split. Found that there was a leak in the joint of the return exhaust from the EGR to the air intake, (fine mist). Had to clean the existing mist from the front and bottom of the engine, in doing so I had to disconect the EGR at the return air intake and remove the accelerator module, to do this I tied the vacuum lines back out of the way. Finished cleaning the engine and started to put everything back and I noticed the the 2 connections (see picture) had come off and I do not know where the connection fit, I have put red tape on one of them to make it easier for someone to tell me which one goes were. I have tried putting them on one then the other nipple, does'nt make any difference to the loss of power. I have check the vacuum on all of the connections and could not find any leak. The car starts and idles normally, checked all the hoses no splits. (had a similar problem with a split hose, loss of power)

rhh or rhr engine. It looks like they're vaccum lines that go into either the egr valve or air intake valve's (on the rhh engine, there are two and one sits behind the intake hose).
That t piece is broken needs to be replace in feeds the turbo
Thank you for that
i would follow dmc's advise. He is the man.
Thank you. Further to the rear R & L lower stability bushes. quoted $ 206.00 for them, then told no longer available, then told I had to buy the stabilizing bar with the bushes in situ now $370.00, so I sent photos of the said bushes, to be told that they are split so as to accommodate installation. so now the cost is zilch, nothing wrong with the bushes!!!!
Thanks will replace it. Could you tell me, which nipple the vacuum hose from the T piece with the red tape goes on, top or bottom?
It doesn't matter it's a vacuum tank the way they sit is ok to repair the t piece you get a washer t piece then add vacuum line to the ends and cut the old one out
Thank you. will do tomorrow, I have a T piece from my gardening watering system, should do for the intrum.
It's probably better than the factory one anyway
Unfortunately that did not solve the problem, still not accelerating as normal, I'm pretty sure there is a leak in the vacuum line(s) will have another go tomorrow, I'll take each one of the lines seperately, hopefully I'll find the trouble.
Checked every vacuum line from the vacuum pump could not find a leak, they all held a vacuum without loss. So next I will check the tube at the (L) back of the motor (as seen looking from the grill). There is no problem with the power brakes they are working fine.
Tune later for result!!!
