Last week, after sorting my "heater box" coolant leak, I was trying to sort the static timing on the S14. I ordered a cheap Chinese timing light off of Amazon because it supported 2/4 cycle ignitions and the EDIS-4 module doesn't like my Innova 3568. I hooked it up, started the engine and tried the new timing light. Well, the RPM readings were right, but the light output was weak and the timing mark was jumping around like crazy (rock steady with the Innova). I sent it back to Amazon and bought the fancy, high-end Innova with 2/4 cycle support.
After the timing session, I came back in the garage and was greeted with a pool of coolant from the radiator overflow hose. Back to Amazon and bought a matching coolant reservoir. Installed it today.
