[brthrurik]

Friday I put on a new valve cover (including new gaskets and sealant) and changed oil and filter. Driving around, car developed a weird idle and died on me a couple times. No problems, started right back up. seemed to die only when large load on electrical system. didn't drive it anymore... Saturday started my day out, car idled fine tested battery, not up to par, drove up to parts store bought yellow top and Seafoam went home added seafoam to crankcase oil as per recomended instructions. started car, no oil pressure (oil lamp came on) anytime idle below 900... figured oil too thin, drained oil and seafoam (consistency of milk and black as night) changed oil and filter once again using heavier weight oil, started car and it ran fine. This morning driving to work car knocked three times and died... now engine won't even turn over...
