...the damn CRHA has so much play in it that the wheels are able to make contact in the housings. At first glance, the turbo spins freely but after further examination, it looks as if I do, indeed, have a blown turbo.

Oh well, at least we now know what the ECU does when the turbo is bad.

Thanks for everyone's help,
Mike O.

P.S. anyone need a paperweight?

Bummer. How long had the K04 been in?

Mike O.

It was a hybrid and it lasted 75,000+ miles of abuse

Doesn't owe you much then. Still a hassle and expense but .. stuff happens.

These are essentially oil bearing turbos. Hammer them without taking good care of the oil and they will die ASAP.

...for the winter. The car has less than 4000 miles on it since the switch.

This is the first time I've used anything but Mobil-1 15/50. I have been getting some lifter tick and figured that the lighter oil would cure that (it did) and help with cold start up wear.

Did the 10/30 cause the turbo to fail? I doubt it. Did it indirectly shorten the life of the turbo? Maybe. Suffice to say that I will only use 15/50 from now on.

I have literally 100's of thousands of miles on overboosted turbos on 5w30 synthetic. But if you are romping the crap out of it all the time, it probably is helping you as far as life of the part goes.
