are there any other engines compatible in my 95 RS. I am having trouble finding a 420A motor and am looking for possible solutions. My rockers seem to be bad and make a really loud ticking/knocking sound, what kind of damage does this cause if they are left unfixed for a while. I guess this has been happening for a while but Ive only had the car for a about a month and they just all of a sudden got worse today. Someone told me that they might just need to be adjusted. Are the rockers on these cars adjustable?
