Car - ADM AE86
motor / part in question - 7AGE
problem - Engine running on 3 cylinders
occurs/started when (if applicable)- Driving
personal situation (if applicable)-
Ok, two weeks ago I was driving home and I started to hear a rattle so I pulled over and it seemed to be coming from around the exhaust cam. I kept driving then as I got round the corner from home the engine started vibrating and dropped a cylinder. I suspected bottom end bearing so I drained the oil and cut open the oil filter and found very fine metal. This made me think it was definitely bottom end cause I had my head fully rebuilt by a top mechanic 6 months earlier and had no problems with it. Pulled the sump off and bearings were stuffed. I had trouble finding a decent replacement short motor so I went 7age. Got a very low k's 7afe and got it all together. Fired it up and it has the same problem as before. Cylinder 3 wont fire and there is a rattle in the head. It has good compression in all cylinders and has spark. The rattle sounds like its coming from around the dizzy but I checked it out and it's fine. The valves looked ok when the head was off. I haven't dialed it the cams yet but they are close so I assumed it would run rough until I did. Not sure what else it could be?
