I didn't see if this was already addressed, but did you mistakenly switch the AOS and crank case breather hoses? I did this once a while back and after a quick spin down the street (same issues you mention) I immediately knew what I did. Just thought I would throw that out there. Sure sounds the same to me.

I checked but they are connected as they should be.

If the airbox with restrictor is to small would i not see that on the afr readings?

I modified my airbox this morning to allmost 3" all the way. But just wondering.

Small update, i fitted the 3mm restrictor but not much different. The aos hoses all are connected as they should be.

What i'm getting is this:

Today again.. Massive traffic due to road work. So in first gear accelerate decelerate etc and while coming to a stop my blue smoke overtakes me... A real cloud of smoke each time i hit the gas.
After 40 minuten of this bs i could finally get a normal speed and noticed constant little blue smoke. Only after a few minutes it stopped. But at the next traffic light after braking and coming to a stop again blue smoke.

Could this be the turbo or should i suspect the cilinderhead?

An easy way to see if it is the cylinder head is to check the spark plugs.

pa951

Ok, what should i see? I'll make some pics if i can ge the sparks out.

Two seem to be a bit oily..

Looks like some of that smoke is coming from the head. How long has it been since the head has been refreshed?

pa951

10.000km ago. Two years.

If it would be the turboseals when would the smoke come?

I could change the restrictor for a 2.4mm will try that next week i think.

pa951

You can't really switch them i thought there was only one hose from aos. Any pics? All help is welcome

Darwantae951

If you connect the AOS hose to the intercooler to throttlebody pipe, you will pressurize the crankcase under boost. Some people have accidentally connected it there and were burning oil.

pa951

These look ok.. Hardpipe hose is from the lindsey racing venture delete kit.
Aos hose goes to j boot. That should be fine. Maybe the head wasnt done correct the last time. But would be a waste of money if it still smokes after i get the head redone. Pff dilemmas.....

pa951

The small hose from the aos to the j boot had a small rip. But would that cause such troubles?

What was the outcome for the turbo oil leak? Did the restrictor work? What size?

I bought a hybrid turbo K26/TO4E from Broadfoot Racing, literature said bolt in to 944T. Now I have massive oil leak into the intake. Do I need a restrictor?

bw993

Yes, you will need an oil re-stricter for this turbo. See this thread for the correct re-stricter size, which can be purchased from Summit Racing. I also had to install an additional gasket for the oil line where it attaches to the mount. I've been running this same turbo for two years on the track at 21 PSI, with no oil or smoke issues.

funny to hear that Mr Broadfoot is hard to get a hold of when things aren't going well, especially since he openly mocks other vendors. i wouldn't give him a penny if he was the last 944 vendor or the planet. i would rather part my car out. sorry, i know this doesn't help you with your problem, i just hate arrogant people, especially when it turns out they're human just like the rest of us.
