[200q20v] Autox'ing and Re New toy

[Brandon Hull]

Yes I'm using the stock CQ pump, rack and accumulator.  OK, so return lines
are all open to atmo., but how about this:  the bomb gets _over_ charged by
the overworked pump, and pushes more fluid into the resevoir.  It overflows,
and sprays around the engine bay due to the car being thrown around.  Maybe
aided and abetted by a slightly overfilled resev?  I don't remember that my
wife complained about losing PS.  But that Pentosin is a pain to clean up.
