My friend has a 1998 ford mustang gt with a 4.6 SOHC and its got around 122,000 on it, and he was driving it to work one day not really hurting it but drivin it normal and all the sudden it started to get a little knock, and i never heard it until today we decided to change the oil in it and see if maybe it'd go away, we talked to one of the guys that owns a carquest here in town and he said that it was the synthetic oil he was runnin in it, he said that stuffs disasterous on a 4.6, and i heard it finally and it only has a knock around 2 grand, and then it starts to go away, and you cant really hear it at an idle, and if you do you have to be crouched down by the drivers door to hear it, he thinks its a rod knockin im not sure really cuz i dont see how it can knock at 2 and not get worse when you rev it up more and theres nothing at an idle. he's talkin about pullin it and rebuilding everything and im tryin to get him to have somebody look at it to make sure, and i was woundering if anybody out there knew of a good mustang mechanic in iowa.
