But flatness isn't the only sealing surface consideration. The level of smoothness or "tooth" is also important. If it's too rough, the gasket won't be able to fill up the scratches. For years, people said that if it's too smooth there won't be enough bite for a good grip, so there'll be unwanted movement in the sandwich.

Historically, automotive ignition systems needed more maintenance than just about anything else on the car. Not only would the points, plugs and condenser need to be replaced frequently, but to assure good performance the ignition tim- ing had to be reset between tune- ups because as the points' rubbing block wore, spark was retarded. Also, the distributor cap, rotor, coil and spark plug wires were all sub- ject to various kinds of damage, such as carbon tracking, so were routinely replaced. Today, of course, everything is different, and the term "tune-up" has become an anachronism. On the other hand, ignition systems are vastly more sophisticated, so every- thing involved has to be in nearly perfect condition or you can expect driveability, performance and igni- tion problems, and diagnosis has definitely gone high-tech. The purpose of the ignition sys- tem is to ignite the compressed air/fuel mixture at the instant that will generate the maximum power and the minimum amount of emis- sions. Spark timing is determined (TDC). Distributors, rotors, and | Nissan was one of the by a table of data inside the elec- spark plug wires have mostly been first carmakers to use Coil- tronic control module (ECM), which replaced by Coil-On-Plug (COP) On-Plug technology, which looks at engine rpm, load, tempera- technology, which Nissan was one ture, etc. Feedback from a knock of the first to employ. eliminates many of the sensor will cause the ECM to retard When the time is right to fire the components that were the timing to prevent engine dam- spark, the ECM will send a signal to prone to problems. age.

There are a number of checks a Nissan or Infiniti tech can make on cam and crank position sensors. The best is using an oscilloscope to view the output waveform, espe- cially when there’s a concern over whether or not a sensor is intermit- tent. Far less reliable, but quick and easy, is a resistance check of the sensor, using a DMM.
