Re: Longevity of v8q engine/tranny

The v8 can last a lot of miles just like most german engines. 1 qt./1k
miles is more than acceptable consumption. The cylinder liners are not
silicon treated, but rather they are etched to expose silicon crystals.
Very hard. In the evnt of a rebuild, I've seen on other makes that they
decide to insert a liner in the cylinder because boring the cylinders and
not being able to etch the iron, not finding oversize pistons, etc.
