Default PT Cruiser Turbo shutdown

Several people keep telling me that you need to let your PT idle for a minute or so before shutting off the engine to let the Turbo shut down. Has anyone else heard about this procedure? My friend is having to replace his Turbo and he is saying that this is the reason. Please help!

If you do a fast shut down on a turbo engine after coming from a hard driving the turbo will keep turning with out oil pressure thats why the bearings will go bad on them! Just let the car idle for couple of min and you be fine!!!

I'll bet your friend didn't have synthetic oil i it!
If you take it easy the last few miles before shutdown, and have sythetic oil in it (a MUST for turbos) you'll be fine.

One other question. What is the rule for delaying cranking a turbo. We had been told to wait a few seconds after turning the car on. Is that a valid requirement? If so, why is that needed? Just want to understand that function.

Also, the post above from BMeador is concerning my sweeties high output Turbo. We found oil in the coolant overflow tank and there was an oil leak under the car. Could not figure out how oil could get into coolant. Discovered there is a coolant line that runs through the turbo just like there is an oil line. Something obviously happened to give oil access to the coolant line inside the turbo. Just FYI in case something like that happens to any of you.

If you listen carefully when you turn key on, you can hear a "whir" behind you - it's the fuel pump in the gas tank - when it stops, the fuel line is pressurized - it has nothing to do with turbo.

Makes sense - there is coolant run to turbo, and oil, but usually oil in coolant is head gasket
You've been here since 2007, and first post? What restraint!

Imagine all the oil is down in the bottom of the engine! When you start the car all the oil start going into the engine and building pressure! By giving some time when you start the car gives the oil a chance to go tru all the parts and build the right pressure for operation!

Now if you find oil in the coolant thats not good at all!!! Normally that happends when the car overheats and starts mixing oil with the coolant!!! Do you see any smoke coming out of the exhaust?

No Rocketman, there was no exhaust smoke and the engine did not run hot. Performance was just fine also. Dealership replaced the Turbo under 7 yr/70 warranty. We also had the cooling system pressure washed as well as the coolant overflow container. This should make the cooling system perform without pushing motor oil through it Warranty did not cover the pressure flushing even though it was needed and caused by a covered problem.

Thanks for your input

I remember reading in a magazine years ago about this sump pump for turbos. It would pressurize the oil system before starting the engine and then would run for a predetermined time after shutting the engine down so the turbo stays lubed for awhile.. Has anyone come across this item?

It's called a "turbo timer" I believe.
