Hey everybody,
Lately the engine in the wagon (I believe it's from an 87 CSX) has developed an ever so slight knock. So slight that I think most people wouldn't notice it...it doesn't seem to be a wrist pin noise, because this engine already has that, and that goes away once it's warmed up.
This noise doesn't go away when warm. I was thinking that it was a rod bearing on the verge of becoming a problem, so I pulled the pan. #1 rod bearing looks very good (to me). I figured no matter what, I'd change these regardless of how they looked. The problem I'm having is that I thought the bearing would be stamped with it's size (10 under, 20 under, 30 under, etc). But it is only stamped with a date "4-98" and above that it has the numbers "85".
Of course, I have 3 sets of "STD" bearings, and this one is obviously a smaller size. Anyone know what "85" stand for? I can't find a listing for an .85 bearing, and there aren't any other markings, so I'm not even sure which manufacturer this is.
Thanks in advance!
