TURBO AFTER OILER

[GALVANIZEDYANKEE]

Canton Accusump makes a turbo after oiler. They sell for about $200.00. This device is connected between the turbo and the turbo oil feed line.
The one-quart size is 3.25 in X 12 in. I figured to installing it behind the inner fender. It will operate in any position. It fills with oil when the engine runs driving a loaded piston to one end of the device. When you turn off the engine the piston pushes oil back through the tubo bearings. I think there is a check valve that keeps the oil from going back up the feed tube. Its advertised purpose is to eliminate turbo bearing wear during spin-down.

When I posted a similar thread in the now defunct PT Cruise Club it got a mixed bag of pro and con comments. However, I have never found a Cruiser Turbo owner who has used one.

Has anyone tried one of these after oilers?

These were more relevant before synthetic oils and water cooled bearings. When dino oil sat on the hot bearings after shutdown it would coke on the bearings. The coke would be like small grains of sand on the bearings and when you started up again it would do what sand does and prematurely wear out the bearings. I only got about 40K miles out of a turbo on one of my early turbo cars back in the 80's. That was before I started using synth oil. Fortunately the warranty replaced the turbo and a friend of mine at the dealership recommended I switch to synth oil. I did and the second turbo was still on the car when I sold it at over 200,000 miles still doing its thing. This was even before water cooled bearings. Now with the combo of synth and water cooled bearings we have today this really is not needed. Big turbo diesel trucks still seem to use them but that is a whole other application. I am just talking cars.

Your Turbo logic sounds good. I actually posed this same question to the now defunct PT Cruiser Club, and got mixed responses. However. one response was identical to yours. I am going to follow your advice. I use synthic oil, and allow spin-down before shut off.
I have owned various turbo cars. The early ones had poor turbo bearing life.

This is my first experience with the Cruiser Turbo. Mine makes a wheezing noise every few second while at idle. It is a very low sound level. I have tried to locate the wheez with an electronic stethoscope, and a listening tube. No luck. I have owned the car for a year. I bought it with the noise.
Nothing has broken. the sound level remains the same, and the car runs great. I can only assume that the noise is normal. Any comments?
