Yes still at it. New suspension is taking a bit of getting used to, it's better on one hand but not on the other, but that's best kept for a different thread. manifolds are on, it seems a little more smokey, does that make sense to you?Hi Ben, you're still at it ? How are the new manifolds ? I will make a few sets myself, got most of the bits and flanges ready to weld so i will have to get into it and finish the car...
HI Andrew, yes I used a flame thrower!!!Hi Chris,
BBQ the pipes - got it! I will try and get at the rubbish near the valves with vacuum cleaner and small brush.
Will contact you once I get the injectors from diesel Bob, I expect them Wednesday.
I will remove the old injectors perhaps Friday. Do you have a rough idea when you will pass by?
just kept me know for planning purposes.
HI Ben, did you check the air filter ? Had a friend on which the turbo sucked the air filter in and got damaged in the process, also were there any debris in the new manifolds ? Had a few cars with bad manifolds that jammed the vnt mechanism and produced the drone as the exhaust gases did not spin the turbine anymore due to damaged vnt ring...Disaster with my allroad yesterday, went up country, had a spat of driving in limp mode and an audible change to a louder drone from the exhaust, eased off and it cleared so carried on for 3 hours. Parked up had a full day shooting, got back in the car at 5, drove off, all good.
Hit the motorway same spat of limp mode and same sound, a louder drone, eased off, it cleared, so I carried on.
5 miles from home BLUE SMOKE, bitch... not bellowing out but noticeable.
Dropped my friend off, still smoking even on idle.
Got home, plugged in, no fault codes.
Left it overnight, started up next day rough idle. I have just changed my exhaust manifolds which lead me to check the turbo. So I took off the exhaust side and stated her up. The wheel is badly coked and the chattering was quite severe.
I have taken the turbo off, there is play in the shaft and there was a clip missing which holds the actuator arm in place, however it was still attached. It is now off to adam at tdi turbos.
When I first put the manifolds on I took it for a spin and forgot to put the vacuum pipe back on from the n75 to the egr, this was quickly rectified as I heard the same audible drone.
I have checked the egr and it's fine.
I have checked the pcv that is fine too.
Oil feed to the turbo is fine and I have just serviced too, oil level was spot on.
So I'm looking for causes, if anyone has any ideas?
also wondering is it ok for me to start the engine without the turbo in place (obviously making sure the oil feed goes into the return) to rule out valves or piston ring wear.
