GM Tecs. CORVETTE OIL PUMP dry sump??

[Alan Nyhus]

A pal of mine has the same car. His has two drain plugs...the one by the filter drains the oil from the pan. The one in front drains the holding tank/reservoir. You fill the new oil into the dry sump reservoir not into the valve cover. I know his holds right at 8 quarts.

The rear pan plug will only drain out around a quart. It's possible that's all that was drained, then 8 qts of new oil was added. Not hard to see how it could hydraulic, especially if the oil was added through the valve cover. Nothing would seem wrong until you started it.

Let us know what you find out. -Al
