Acert Broken Rings

A couple of weeks back I replied to another members post about acerts , The thread is locked now so here is an update.

This acert was using oil,and had bad blowby, the oil level dipstick had been forming a dark caramel gluey build up from the oil level to the top for some time, it actually lost a slight amount of oil pressure in the end, from combustion gass burning the oil and carbon and soot slightly clogging the oil filter.

Here is what we found. It was torn down just in time.

 

Yep #1 and #6 were broken, it will be getting the high load rings when it goes back together, another interesting thing, is in 12,500 miles between oil samples and oil changes this has developed rapidly. The last sample was an A

 

Will post tomorrow to many part numbers stored in my head , but not this one .

 

With the 10 or so southern hemisphere Acerts I have had my hands on, all southern hemisphere highway work, ( which appears to be similar if not harder to northern hemisphere off highway work) the 10 combined are probably close to 6213800 miles , I have personally only seen one turbo fail, and this was because a nut came loose and the turbine housing cracked. May have been lucky with the updated sleeves but some real world results for you all to chew on.
