Had a read on the GM engine and it looks really interesting. One thing did give me a pause. The belt for the variable flow oil pump has to be changed every 150,000 miles. Changing it requires removing the transmission as well as the transfer case on 4WD's. Might be an issue for high mileage drivers.
And to top it off, the belt is running wet in the oil, and the 150K is simply an estimate that many auto technical experts do not believe it will make. This is what I read shortly after the engine was unveiled.
They put a timing chain in for the cams but could not see doing that for the oil pump, wth were they thinking.
