I have a 1992 Daytona 2.5 4 banger.. on start up it idles hig as usual but
today it had a rattle.. then if I rev it up over 2500 in neutral.. it sounds
like a bearing noise.. Is this the rod bearings.. ?.. People kee saying
piston slap but I have had 2.5's with that and this doesn't sound like it..
Any info would be great
