Hey Scotty! Congratulations for overpassing Top Gear! That´s sign of a very good job indeed.
By the other hand, here I have a good question for you. Today I inspect an old 2002 Kia Rio 1.3 SOHC manual transmission with 90.000 miles for my first car of my own. It´s quite cheap, nice and very fuel efficient. Searching on the internet I found that its compression ratio is about 9.4 to 1. Which according to the maths and my country atmosphere pressure, it´s compression SHOULD be around 150 psi.
Testing it everything was looking fine until we make the dry compression test. The results were astonishingly high. 206 , 190, 190, and 200 PSI!!!!. No mayor differencebetween dry and wet test (3 or 4 psi more or less); here is a picture of the compression tester for the dry test. I know that low compression is bad news, but SO high compression is good? Cylinder walls without scores (checked with a borescope). Pistons head with a bit carbon build (checked with the same borescope). Transmission shifts fine and clutch doesent slips. Drive train is ok, litle shakes between 55 and 60 MPH but nothing serious. Wheel bearings without any play. Cooling system in decent shape and without any sign of fumes going throw it due to eventual head gasket leaks. Wirings in really good shape. Alternator giving 14.2 volts. Frame and chassis straight without crashes and no rust. Windows, windshield and headlights without any type of scratches. Interior in decent shape, but the driver seat a bit worn out. Panels are all in quite good shape. Single owner and is a good old man. What´s your opinion? Thank you!
