Engine update




The damaged engine was delivered to SVS last week, but the last of the parts didn't arrive until Monday afternoon.

Still not certain as to why our engine failed at BIR, but it involved oil starvation. The rod and main bearings are all scored. The #1 rod bearing looks like it spun on the crankshaft, leaving scratches on the journal. Hopefully it is deposits and not scratches so the crank might be salvageable. Pistons in the damaged engine look better than the ones from our donor engine, so Mark will probably use those instead. He said the cylinders on the new block look good and honed out nice and smooth. It all goes back together today (Tuesday). It needs to get to the shop in Maple Grove on Wednesday for evening installation.

It looks like it will be a hot weekend in Iowa, partly cloudy with daytime temps around 90F and overnight only down to 70F. The race course uses a lot of the oval, so wear on the right front tire will be unavoidable.
