Idk about the chains and retainers,the previous owner i bought it from did maintenance to it but they couldnt find their paper that had the list of what they did to it...no weird noises coming from them though so they arent bad or going bad...ive been trying to research that problem for awhile,its not even a problem really cause it starts every time if it takes 1 try or 3...

i was gonna pound it and keep it but i want a e28 or e30 real bad,thats what i wanted before i got this car and i finally found one sooo gotta sell it..
