OK, here is the deal. My car has 77k on it. Runs great BTW. But, I bought it with 74k and all records since 54k miles. Prior to that the car was sold from Curry Acura in NY. The timing belt was due in terms of time before it was sold to the last owner at 54k. Problem is that Acura does not keep service records past 2 years, so the info was not available from Curry Acura when I called them. Looking down the front of the engine all I see is the black bulge from the cover and a double triangular looking piece directly below it but no weep hole like you all decribe. Do I have the new pump cover or not?? If it was replaced it would have been in 1999 at 54k miles?? Please help. Also, if I don't have the new cover and the belt has not been done am I pushing waiting till 90k to do it??
Still wondering about timing belt??

It does not sound like you have the weep hole and therefore I would assume that the belt hasn't been replaced.
Can you push it? That's up to you. I wouldn't take the chance.

If you can’t tell by looking at it and reading the recent posts that attempt to describe the difference in detail, how the heck are we supposed to know without looking? 
OK, let’s try. All covers have a weep hole, the difference is in the location. All covers also have the V bumps because those are timing markers and have nothing to do with the pump, but we'll use them as a reference point. You can see the V, which is just above and top the left of a bolt that sticks out. Just above that is the 4.6 inch diameter round “bump” in the cover. If you still have the early cover there will be a .35 inch hole along the lower left side of the bump, located a little above 8:00 on a clock face and nearly touching the edge of the bump. If there is no hole (or tube sticking out) at that location then you have a new cover and pump. OF course that does not prove you have a new belt.
However, even if you have the old cover you could have a new pump and/or belt. If the pump has been replaced with the new style they could have modified the old cover by drilling a hole in the correct location for the new weep tube.
The tube of the new pump comes out almost straight down from the old one described above but about 2 ½ inches lower and therefore not nearly touching the "bulge". As another reference, the new one is about three inches to the left of and slightly lower than the bolt sticking out by the V as described earlier. If the weep tube is there then you have a new style pump. But again, that alone does not prove the belt was replaced.
If that doesn’t do the trick, send me a plane ticket.

It depends on what year your NSX is. If your car is a 1997 or later NSX, then there's no need to do it yet, because the recommendation is to do it at 105K miles or 7 years, whichever comes first. If your car is a 1991-1996 NSX, for which the recommendation is 90K miles or 6 years, then it is overdue based on the time interval, since it was due when the car was six years old. How comfortable do you feel driving around on a timing belt that (depending on the year of your car) may be up to 13 years old? Remember, if it fails, you could have an extremely expensive engine repair on your hands.Tebbnsxr said:

To check for the old style cover, I would just feel at the 8:00 position on the side of the bulge. I didnt see anything when I checked, but when I shined a light from the back of the car pointing forward, the hole was very visible. It pretty much touches the side of the bulge, and from the above viewing angle, it is shadowed and almost impossible to see. Just reach down there and feel for it when the engine is cold.
