Hi, thanks for the advice. I do not have any service records from the guy I bought it from. I will check to see for sure but I believe it knocks at anything under about 1300 rpms when cold. I will let you know if the adjustments you suggested work. Thanks again Rod

Hey there, I'm new to this site so please forgive me if I screw up this posting. I have just purchased a 1986 radian with aprox 27,000 miles on it, it runs great and pulls hard but it has a knocking sound coming from the engine when at idle when cold. once it warms up and is at proper idle speed the knock goes away. You can aslo make the sound go away when cold if you give it just a little gas to bring the idle up. Does anybody have any ideas about the cause of this noise, I was thinking maybe timing chain slap or maybe low oil pressure, although the oil light does not come on? any help would be greatly appreciated.
