  • Checking/Changing Spark Plugs

    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. You MAY be able to disconnect it temporarily, but I've never had to do it myself, so I don't know how much time/complexity it would add to the operation. ...

    Oil Change

    OK, I'll admit, most of my 60V6 oil change experience comes from a 3100 and 3.1 in W-Bodies. The concepts will remain the same, but the details may differ.

    OK, let's start with a list of tools you'll need:

  • Using GM Top Engine Cleaner

    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 in a well ventilated area. This is going to cause quite a smoke ...

  • DIY Degree Wheel

    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". Printed. Worked the same as t...

  • Injector Cleaning

    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.

  • How to read turbo maps...
    Driver_10
    There have been a couple of guys who wanted to know how to read a compressor map. Hopefully, I haven't made any mistakes this time (unlike the last) and this will prove to be useful to you in your understanding of a compressor map. Reading a turbo map isn't as difficult as it looks. The map displays 4 key pieces of information. A. It displays the pumping efficiency of the compressor (meaning the amount of actual air that it pumps in contrast to the amount of heat that's created while wasting energy) B. The physical amount of air that it can move in pounds per min (just like it says, how much air per/ min) C. The pressure ratio of the air being pumped (that is, the ratio of pressure that it is capable of that pumping in contrast to the ...

The 2ND is the spacing between the lugs, measuring center point of the lug to the next lug. have heard that 5x114.3 from something like a mustage will work. Our wheels have an offset of +40. Offset is the dist from the center line of the wheel to where the wheel mounts to a hub. A pos offset has the hub/lug toward the outside (away from car) of the wheel and normally found on FWD cars. Neg offset is the opposite. 225/55-16 The first number, 225 is the dist from one edge to the other of the tread patch in mm. 55 is the percent of the first # giving the side wall height. The last # 16 is the dia in inchs of the wheel for the tire.

  • Cruise Control Switch Repair
    davida1_hiwaay_net
    It seems that ALL the cruise control stalks you find at the JY nowadays are non-working. The Cruise switch doesn't work. Tired of paying $40 for a new stalk, I decided to dismantle and attempt repairs to what I had.

    The stalk is glued together and there will be some minor cosmetic damage during the dis-assembly, but if you file down the burs before gluing it back together it is not serious.

    This is the stalk I am going to repair.


    First, separate it at the joint. I was able to grip a pair of wire stripper pliers into the joint and force the stalk apart. Slide out the switch by feeding the cable into the shaft.
    Pull off the outer end of the stalk housing. The SET button cap will po...

  • V5 A/C compressor tear down / re-seal...
    davida1_hiwaay_net
    Pictures of tear down and re-seal of Harrison V5 air conditioning compressor. These are very common on the 60V6 engines. They are very costly as a re-manufactured unit. The parts to re-seal them are about $30.

    I did this write-up for another forum but figured it would have interest here.

    I started with this unit. I had it on my 1972 Chevy Nova until it started leaking around the housing o-rings. It still cooled fine, it would just lose freon over about a 2 month period. It will go on a 2.8 carburetor engine in an older a-body car. I will be changing the pulley to a vee-belt pulley.


    First, remove shaft nut and install compressor clutch hub puller.


    Remove clutch hub, making sure not to lose the key!


    Remove the snap ring that retains the pulley to the compressor.


    Install a puller, making sure the puller bolt ONLY presses on the neck of the compressor, NOT the shaft. The socket sits on the neck, protecting the shaft.


    The pulley off. I will be changing this out for a vee-belt pulley.


    Now use the puller on the clutch magnet.


    OFF with the clutch magnet!


    Nasty looking. Will need to clean this SPOTLESSLY clean before opening it.


    After a few minutes with the Purple Soap and pressure washer, it's all clean!


    Remove the external parts. Take out the compensating valve and the oil plug.


    Remove the bolts that hold the compressor together.

    Use a soft hammer (or b...

  • WOT-Tech pistons and the CR Calculator
    bszopi
    With all of the different top-end swaps and bottom-end builds out there, I was talking to Ben at WOT-Tech about the Diamond pistons and how different setups would affect the compression ratios (CR) of the pistons he was offering. I wanted to pass this piston information on to the users so that they could then determine what their final CR would be with any setup. Due to marginal sales, WOT-Tech has decided to no longer list or stock specific CR pistons anymore. What does this mean to everyone? It means you can tailor the pistons to suit your specific application, no matter what components you are using.

  • How to Re-New Your Cracked Dashboard
    60dgrzbelow0
    I searched the forum for any postings on this subject and drew a blank. Although this fix is related to any F-Body, I wanted to share it as a possible solution for anyone replacing their dried, crusty or shattered stock dashboard cover with a durable new cover and one that includes an inexpensive way to solve the lack of vent covers that most of these covers present with. Here is what you will need to do the job correctly and fast, too....:

    To avoid "a thousand words" that follow... here are the "Cliff Notes" images of this entire job ...
