1qwk767 Posted May 18, 2006 Report Share Posted May 18, 2006 A guy from work has a 91 civic, with the MPFI swap, i/h/e, cam gear, MSD sport compact ignition, and stuff, well he is wanting to turbo his car, well he ordered his fuel parts like fuel pump, injectors and his safc ||. Well after the fuel pump was installed the car ran fine, well he installed his DSM 4500cc injectors, and his safc|| and the car ran fine that night, and half way through the next day, well the car starts running bad and doesnt want to stay running so he swapped his stock injectors back in, and reset his safc, well after he did that the car started up and idled fine He notices white smoke coming from his exhaust and doesnt pay much attention, well after he backs outta the driveway the car sputters and shakes while trying to accelerate and drive down the road, he did also notice his coolant over flow tank over flowing after it ran 10-15min sitting still and idleing Thanks Mark Quote Link to comment Share on other sites More sharing options...

1qwk767 Posted May 20, 2006 Author Report Share Posted May 20, 2006 went over last night after work, started the car with radiator cap off, let the car warm up and the coolant started to show bubbles on the top of the coolant, and we shut the car off, it had quite a few bubbles, so Head Gasket it is cool Mark Quote Link to comment Share on other sites More sharing options...
