Hello,
Today's subject is an '82 Camaro with the infamous "Iron Duke" 4 banger and appx 96,000 miles. Car ran great (80 mile round trip each day, no problems) until it simply quit without warning one fine day on the interstate. A compression test was performed and the engine has virtually *no* compression at all (first cyl 8psi, 2nd thru 4th appx 12 psi, throttle wide open) which ordinarily would lead one to suspect the timing chain except this engine doesn't have a chain, it has gears, and the camshaft and valve gear are still rotating when operating the starter. Can timing gears "skip time" like a timing chain can? Could a blown head gasket or plugged exhaust system be to blame, or perhaps something else? It's not my car, and I've never worked on one of these engines before so any advice would be much appreciated. Also, the manual says the cam has to be removed to change timing gears on this motor....is this true?
Much thanks for any help.
