I am trying to set the timing on my van and need some additional information. I have an 83.5 Vanagon with 1.9 water-cooled engine code "DH". According to the Bentley manual, (my engine code is not listed in the new Haynes manual) In the Bentley on page 10, my timing is supposed to be set at 5+-1 degree ATDC. On page 11 of the Bentley, which says almost the same thing, except to set the timing 5 degreed +-1 degree before TDC. Since there are no timing marks on our vanagons, how can I tell if I am setting it right. BTW, I have the three belt pulley because I have air con. Right now, I have the timing set so that it is lined up with the centerline of the engine. If I advance the timing, the engine runs cooler and quieter? Also, I am having a problem at idle. The engine has a random skip/misfire?. I rebuilt the engine because of low compression thinking that was the problem, but there was no change. I have replaced the ignition coil, replaced the cold start valve, spark plugs and wires, cap, rotor, cleaned the throttle body, dismantled cleaned and inspected the distributor and fixed any vacuum leaks that I could find. The only thing that showed any improvement was when I fixed the vacuum leaks. I am having a problem with the cold start valve, does not work with the engine cold, only with a slightly warm engine, i.e., if I run the engine for a while and it warms up, then let the van sit for a while (1-2 hrs.) and cool down, the cold start valve will kick in when I restart the van. If anyone has any suggestions I would greatly appreciate them. Pete 83.5 Vanagon peterz@gte.net |
