Hello,
Today the shop had taken the engine out of the car, just to replace the very stiff valve springs. When the heads came off we noticed that there are rough areas on the cylinder walls. Not everywhere, but at least two areas per cylinder. FYI: Cylinders are 103.8 mm (by AA). Pistons are also by AA. Markings on cam: CWC Valves Intake: 44.35 mm Valve Exhaust: 38 mm My question to the brain-trust is: What could be the cause for the rough areas? Some back ground info: This car supposed to have "Nickies" Cylinders and JE-Pistons. Obviously the (Craigslist) seller and I are no friends. After receiving it, I drove the car for less then 10 minutes before the car caught on fire.  |
