I have the motor setup in my sig. It was built last summer, but never driven that much until this month. We started off with the motor running on EFI with a A9L mass air conversion, #24 injectors, 255walbro pump, trick flow intake, Kirban AFPR set at 38-48 (tried several). When we first started the motor we let it idle for 5-10 min, checked for leaks, checked pressure and gauges,etc...we revved it up a few times (not high);repeated this a few times. It didn't want to idle much though, b303 cam didn't wanna work with computer I guess. anyway I believe we used a synthetic oil, which I'm thinking we shouldn't have done. The car was driven normal around town for about 2weeks, but ran tike $h!t. We couldn't get the thing to run right with the b303 cam and mass air conversion. It running real rich, even if we turned the fuel pressure down. The car sat for about 5 months without being driven(started maybe twice). Its not my daily driver now so we did a carb conversion and it runs MUCH better. No more problems with computers .
anyways, the car is smoking out the exhaust now. I changed the oil once after the short "break in" and put more of the synthetic oil back in. this oil was in when we still had EFI on the car. SO, if the oil got gassy, and sat for 5 months...my rings didn't totally seat. If I change the oil to 20w-50 and add some "stop smoke" type of oil thickening addative, could this help my rings seat? thanks
also the rings were plasma moly I believe
I'm also gonna get a smaller carb (650dp)
