Hi chaps had and done all the usual things re the smoke issues with my TT its not overfull have changed filters and I have to say is OK,but if I drive it normaly no smoke all perfect, but if Ive been driving it properly using the Turbos for a few miles,when Im driving its perfect but am getting a lot of smoke on startup after a spirited drive,the next time I go to use its OK and does not do it every single time,it also imo does not show 0.8 bar every time you drive it hard through the gears sort of goes to 0.5 then you have to ring it out to get to the 0.8 limit,but does get there.
could the smoke be due to the syphon effect still (no non return valves to oil feeds on turbos)or with the reluctance to reach full boost be worn turbos,it does not smoke at all under any driving condition,overrun lift off ect,any opinions would be appreciated,cheers

You need to put the check valves in. This was the cure for me and TONS of other people. These turbos are way over oiled. Once I put the check valve kit in there has not been an ounce of smoke. UMW sells the kit. When the car sits the oil backs up into the turbo housing and on start-up it gets washed up into the intercooler and intake.... You will have to clean all of that out. Also when the oil is going through the intake it's cutting down on your octane rating.. becareful you can detonate the motor.

cheers much as I thought,thanks for that,by the way with check valves fitted do you run her up to the mark on the stick?

Barney1

No.. I run mine 3/4 when hot...

On a related note, I found it was really difficult to get oil into the car....the filler pipe is narrow and it ended up overflowing and oil pooled at the top without just flowing down. left a nice stain on the driveway! I would say the oil level sender is faulty but its been recently replaced and shows 1/4 full when hot. As for the dip stick....that's also a pain to get in and out....the oil is so clean, it difficult to tell where it is on the stick. Is this the normal experience?

sounds usual goes all over the exhaust,in heat exchangers ect,once you do it does not happen again!! you just have to pour slowly.

Barney1

Pour slower and I use a funnel. GO REAL SLOW...

Taj

Thanks guys.....real slow is an understatement....I have now spilled oil twice....and I don't usually make the same mistake twice....3rd time lucky i think....

compared to my old 964, the oil fill is really slow....there must be a difference is design.

I'm sure that you are aware that the car must be running while filling oil.

Kevin

I strongly suggest running the oil level just above the first line..

speedlimit2

I always fill mine on a friends drive!

+1.....I had 996 check valves installed and have not had a puff of smoke since.

Taj

So tried again last night, just enough to get the gauge into the 3/4 level at idle....literally had to dribble the oil in very slowly and had no overflow....Success!!!

I also have check valves and have seen no smoke. I have seen some oil in the intercooler though....

As an aside, I am running 5W30 fully synthetic long life oil...any views on this?

Kevin, My oil gauge has no marls on it, just a red portion, a white sweeping arc, and then another red....my level is 3/4 up the white arc.

cheers.

any one know of anwhere in the se (uk) to supply oil lines with non-return valves in please,are they just the std ones fitted to a 996tt? a part no would be great if any one knows cheers.

15/50 mobil 1 half way up dipstick seems to be optimum,did you have std 996 oil lines fitted?
