This got posted to our Landshark aussie 928 list, and I figured there's some people here who might find it interesting as a reference point in answer to the questions about "high mileage" 928's.

The guys doing the rebuild are Buchanan Automotive - generally regarded as the best independent 928 workshop in Sydney, if not Australia.

Thanks to Bruce and Sean Buchanan for posting up the pics.

looks like a good write-up

Wow! That is some amazing wear (very little) for that many km/mi. So in the end it sounds like all the did was clean everything (except the intake runners....?) and reassembled with new rod bearings, valve seals and waterpump. I assume all the small ancillary bits as well. That is amazing.

When I did the valve cover gaskets on mine at 216k miles I didn't see a single pit on any of my cams either. So I just gotta get off my butt and do the BG intake treatment to get the carbon off the pistons and be good to go for another 200k miles

This goes back to the old addage, you get what you pay for. In our case, these were high end GT cars and the Engineering that went into not only the Engine but all aspects of the car is clearly evident. Are their areas that are just horrible (HVAC and Electrical systems come to mind) then yes. But you can't deny that these engines were built to last and the cars to be driven.

It's not really surprising. The engine is rated at 316HP. It's lifetime duty cycle has been about 10-15%. Not exactly stressing the metals or wear items. Properly lubricated, and maintained at a decent temp this is the wear I would expect.

the cylinder walls look good.

That is a very good point. My wife's acura is 3.2L. Its rated at 260hp. So almost as much power, but way less cubic inches to do it. And at 93,000, its using oil. Not leaking it. Sealed up great. Its BURNING the oil. Because the ring gaps are getting big, or the valve guides are a bit more open. Its not going through the intake. I checked that.

I don't know a thing about Acura engines but excess oil consumption is always associated with improper break-in, or a design flaw. Most often is improper break-in. (run it hard, get it hot early in the life of the engine).

What oil did you use and what climate temperatures did you experience?
