Did anyone mention these new fangled auto cut off features that are starving the turbos on strained small displacement engines of oil at every stop light?
No? Then where's my curmudgeon cookie for the day? I earned it. Gimmee MY cookie! NOW!~ Last edited by LEAKYSEALS951; 11-04-2019 at 04:26 AM.. |

water cooled turbo's live much longer then the old style oil cooled
I think a auto/off motor should run oil thru the turbo after shut off better ones also run water to prevent over heating/oil coking |

The 944 turbos have the dual oil/water cooled setup with the auxiliary water pump to keep water circulating through the turbo after shutoff. It never gave me trouble, although I did have to go through the auxiliary water pump system and replace the pump at some point. Also, it has a secondary t-stat I think.
My 2005 volvo xc70 was oil cooled only. It never gave me trouble either, but is it a low pressure setup. I do not think the newer volvo engine platform is dual cooled (I could be wrong). Every car salesmen I talk to has no clue if the car they are selling has a water cooled feature. I will say, on the new buick regal tour x wagon I was looking at, the turbo was at least on the front end of the engine compartment, in a very accessible place. I need to see if it has water lines going to it next time I check. |

The op is asking about the turbo itself, not the engine. They are consumable components. While oem or garrett grade stuff is super expensive still, the market is flooded with aftermarket solutions, and most folks are having good enough luck with them.
Any turbo, even water/oil, is only as good as the treatment it gets. Low/no boost for the last few minutes before shutdown, long life. I wouldn't worry too much about the autostop, as the vehicle usually restarts before anything as a chance to really cook.

No issues so far
2007 911 turbo with over 50k miles and 2016 Macan Turbo with over 70k miles and no issues, and the start/stop function hasn't seemed to create any issues so far.

It depends on the motor and the turbo. For example; an early Saab 9-5 turbo 2.3l engine came with either a Garret or a Mitsubishi turbo.....the Garrets were problematic whereas the TD04 seemed to last forever.....the engine lasted a long time regardless of the turbo.

I have and still own an 05 VW GTI with the 1.8 L AWP engine bought new. It currently has 161,000+ miles on it with stock turbo, a Revo Stage 1 tune, bigger intercooler and turboback exhaust as well as other minor mods. Car still has original turbo with 11k mile oil changes. Recent dyno showed 189 HP and 240 lbft torque at the wheels. Other than normal maintenance and 1 timing belt change, no other issues.
