    While looking for pictures of the markings, I conveniently found this old thread about setting the distributor timing. Probably explains it much more clearly than I did.

      I take it you aim it down from the top of the motor. Won't the fan or belts get in the way of the harmonic balancer?

        I believe the balancer is to the rear of the fan and belts so it shouldn't be a problem. It will probably look something like this.

          yes, you have to be careful. Also, you will want to mark the hashes on the balancer with a silver marker or liquid paper or pencil or something that will contrast the rust well in the light.

            Thanks for the link, however, the link's pics don't come up. I wil try a different computer. Besides that, this was very helpful.

            The EGR holds the vacuum (it runs very very bad) when you apply vacuum to it. What do I need to do in the Solenoid side to test it?

              is the timing set correctly? If its too far advanced, it will do this. If it is, back it off a degree or two anyway. If the engine runs lean, it will ping. If it runs too hot, it will tend to ping. If the balancer has spun and the timing marks are just wrong, it will ping because the timing isn't actually correct even if you think it is.

                  I fixed the pictures last night. Refresh the page if they don't load. The other link does have the pics. Same article.

                    I got the pics. I have been reading the article. The only thign I am confused about is marking the lines on the balancer. There is a set of two marks and the single one. Are the Double marks 10 BTDC???

                      You'd have to clean off the balancer to see which is BTDC and ATDC. its stamped in there. There are more numbers on the BTDC side if you can't read the letters. I think the scale goes from something like 30 BTDC to 10 ATDC.


                      THe marks in my pictures are 10, 12, and 14 BTDC. I think the long one was 10 BTDC. THey won't be marked on the car currently, I made those for my own use so I could try advancing the timing to see if it was happy about it. All that you likely have is a rusty area that will need some wire brush action before any of it can be read.

                        understood. Looking forward to get this done!

                          While I am there I want to check the EGR system:

                          Check the Green hose to ensure 0 vacuum (at idle)
                          Check Red hose for 28mm hg vacuum (at idle)
                          Inspect valve (put vacuum to it to make sure it stumbles and stalls)
                          Inspect solenoid on passenger side wheel well (how would one inspect this?)
                          What else should I test for?

                            engine vacuum is typically 16-20 inches of mercury, not millimeters.


                            About all you can do with the solenoid is pop the cap off to clean the filter out. if the filter turns to dust, just leave it out. Squirt some WD40 or similar down the tube that poked up into the filter too. A clogged filter is usually the cause for vacuum on the green line at idle.


                            Pull vacuum on the green hose at the solenoid to make sure it opens the EGR valve. A leak between the valve and the solenoid will cause the whole works to not operate.

                              ok so i pulled the codes. Here is what I got:

                              Attaching the jumper wire btw the terminals I turned the ignition to accessory
                              Right after I did that, a very very quick blink happened. Six seconds later, another very quick blink happened.

                              Three seconds later I got a 1 second long blink - 2 seconds later another one. 4 seconds later another 1 seconds blink followed by a 2 second gap and another 1 second blink.


                              8 seconds later a got a 1 seconds blink, followed by a 3 second gap than three quick blinks, a quick pause (no blinking light in between to separate), and then another 4 quick blinks.

                              3 seconds go by and it repeats the same 3 and 4 blinks


                              Now the way I look at it, it told me:

                              11 -----34---34

                              I don't know why it would repeat 34 ttwice???

                              Can anyone help chime me in here???

                                it displays codes twice. The blip right after key-on is the cylinder ID code for the code scanner. The first pair of 11's were for key on, engine off. The two "1" codes were actually 10, which is the spacer code between KOEO and CM code output. The second set of codes are stored memory codes. All that tells you is that at some point in the past, the EGR valve screwed up.

                                Start the engine and do the code scan. that will functionally test the EGR now.
