Checking/Changing Spark Plugs
OK, here is a fairly simple task on the OHV 660s that can be made MUCH easier with just a few tricks. Most of this will apply to FWD, but the RWD vehicles are a bit simpler. And the rock the motor method described works perfect for a 3.1/2.8 since it doesn't have the lower mount that a 3x00 does (in a W-body anyway), so no damage can be caused. On a 3x00, there is a mount near the balancer that can get torn by rocking the motor, so be aware. Mine was already destroyed, so I had nothing to lose.... -

Using GM Top Engine Cleaner
The basis for cleaning the top end of your engine is pretty simple. The EGR system recirculates exhaust gases which deposit carbon all over your intake manifolds and the intake port on the heads. The backside of the intake valve is also a concern as the carbon not only attracts the fuel, but also changes/lowers your airflow. Efficiency and horsepower are lost over time. To use the GM top end cleaner, you can use either the spray or the liquid, though I prefer the liquid. First, start i... -

DIY Degree Wheel
Originally from Machinery Cleanery, you can download the resized version for use on the DOHC timing gears here. It is easiest to print these out on CD labels and then to a CD you don't care about. They bolt right up to the cam gear using the stock bolt, and allow you to time the cams prcisely. Remember though, every degree on the cam is 2 on the crank, i.e. 6.5 degrees cam for 13 degrees crank. Additional note from RednBlackCutlass I used Project Sticker Paper (Wal-Mart), Resized to 4.625"... -

Injector Cleaning
...This article brought to you by
A fuel injector is nothing but an electronically controlled valve. It is supplied with pressurized fuel by the fuel pump in your car, and it is capable of opening and closing many times per second. When the injector is energized, an electromagnet moves a plunger that opens the valve, allowing the pressurized fuel to squirt out through a tiny nozzle. The nozzle is designed to atomize the fuel -- to make as fine a mist as possible so that it can burn easily.
