First a little info:
Recently purchased
91 GT 5 speed
all stock except CAI and pulleys (still has smog and A/C)
PO says the timing is at 14 but I have not confirmed
73K miles
I honestly think it has been driven fairly hard or not had great maintenance.
So as I was working on the A/C today with it idling for awhile (5-7 minutes) in the garage I noticed the black soot on the ground from the left exhaust only.
I am suspecting valve seats but I don't notice any smoke. Could this also be a sign of running rich or some other problem? Seemed to have a lot of condensation as well but the oil didn't indicate a head gasket problem when I changed it the other day. Car idles pretty well and performs ok but not great (of course it is stock compared to the 90 LX I had many moons ago).
I am not too concerned with it right now as my goal is to get chassis components refreshed/upgraded including sub frame connectors. Just curious so I can get myself edumacated.
