Mike, if the heating element is still working, you can clean the coke from a clogged AAR by doing the following:
1. Fill the AAR with solvent and plug the ports.
2. Apply 12 volts and let it heat up good.
3. Remove the power source and drain the AAR.
4. Repeat the process until you can verify the plunger is moving in one direction when powered up, and the opposite direction when power is removed.
It's advantageous to shoot compressed air through the ports to help to remove the debris.
I've done this to several AARs
Hi Mark, thanks again for this suggestion. I ordered and received Gunnex 2000 over here in Germany, which is a gun oil (ballast oil?) that seems like could be the best product available for this purpose.
I was expecting the main body of the thing to fill up with the stuff, but apparently essentially nothing is getting down into it and I can only squirt low volumes of the stuff into the openings before it bubbles upward due to an apparent lack of access into the main chamber. Is this to be expected?
I didn't hook it (them, as I have 2) up to power but did put them in the freezer, then into the oven, then into the car. One was open, but after a good 8-10 minutes, my idle was still just as high as it was to begin with, almost 2,000, and the thing was apparently not closing at all. Damn!
The other one allowed the car to idle (closing off the vacuum 100% causes the car to stall) but was apparently almost entirely closed, but now that I think about it, it must havee still been warm (duh!) from having been in the oven, albeit at a modest 150 degrees or so F. It wasn't anywhere near too hot to handle, after having been warmed up, the other one was open, as mentioned. I'll test the other one again tomorrow if it may be open after having fully cooled down. I'm not op, and I'm ready to just buy/trade
for a known functional one.
Thanks for you're and support would like to hear more about how much oil I should be able to get into one of these things. Also, I cannot see ANY light coming through the two openings at all.
