N2668G

Lifters might as well be coarse sand paper.

I spoke with the mechanic last week who is working on 2668G, the Cessna 182 that I flew for the month of January in Collegedale TN. This plane was donated to GMI around Christmas time, and is being prepped to go to Guyana. They got the new cylinders back. While they were cleaning everything up and inspecting everything before it goes back together, they found BAD NEWS. Because the engine had been sitting for much of its life it had developed corrosion on the camshaft and lifters. The corrosion made the surfaces rough and increased the wear in the engine significantly. The particles that came off were then circulated in the engine oil causing damage to the crankshaft. This means that a thorough tear-down, inspection and rebuild of the engine is required. Fortunately the cylinders, which are the expensive parts in an overhaul, are already purchased. Yesterday David Gates was at the hanger and talked with the mechanic and gave him the go-ahead to complete the overhaul.

Clarification: this is not the plane that I am using in Oklahoma to finish my IFR training. that one is a Cessna 172 that looks similar but is smaller. N4192F seems to be working just fine. I flew with the instructor yesterday and spoke with the Examiner and they feel that I will be ready for the test with just a few more mock exams.
