Afternoon, Looking for peoples opinion on what this problem could be with my 97 Civic MB3 D15Z8. Started up this morning and sounded like only 3 cylinders were firing. After a couple of minutes idling on the drive it started running smooth again. Drove about 6 miles into work at which point the heater started gurgling. Let it cool down and looked under the oil cap, oil looks clean. Dip stick looks clean. Coolant was over the 'high' mark so I've drained a bit off, but it didn't look oily. Quick vid of the gurgling.
Anyone got any good ideas before I stick some wondarweld in it / scrap it.
