So, after 7 years of blowing up pistons and mis-diagnosis, we have finally figured out what our problem was. (IMG:style_emoticons/default/mueba.gif) We found that even though our distributor was rebuilt and the curve tested, all that was tested was the mechanical advance. Our vacuum advance/retard canister turned out to have a leak on the retard side. This caused us to have about 40 degrees advance at points. Seems we should see about 33-35 total advance maximum (duh 27 adv with disconnect plus the 8 degrees of vacuum advance..http://www.dgi.net/914/tech/distrib.html). We are getting the new part this morning to cure this once and for all.
It has been very expensive over the years with the multiple rebuilds we have gone through (a few thousand). All for a $95 part. One question I still have is about these A1 cardone remanufactured distributors. I got mine rebuilt by a shop and am buying a new vacuum canister. It seems like you could use this: http://www.partsamerica.com/PartDetails.as...ype=218&PTSet=A All I have found is the one for a 1.7L, but it seem sto come with the vacuum canister AND trigger points (same as 2.0L) for $51.99 plus $1 core at my local Kragen. This sounds too good to be true as the trigger points and canister are each about $100. Obviously, the canister is probably used, but tested to spec... but gosh... Has anyone gone this route? You would have to throw away the distributor on the 2 liter cars, but seems worth it if you need either of the other parts. Are the trigger points new? Anyone with first hand knowledge of this?

I don't know whow rebuilts the units for NAPA, but the one I bought had used trigger points that were media blasted and actually didn't work and I had to put my old ones in to get the engine to run.
