when i bought the motor, i told them to do a compression check..it was around 200 psi with alittle oil in the cylinder..but i still need to do a leakdown test...it might be a leaking head gasket because it seem to leak oil right where the head sit in the block..but now it doesn't leak anymore...i have enough oil and a new distributor, rotor, cap, and spark plugs...the engine gets really hot but doesn't over heat...now the idle lopes between 1k to 2k..i know that it might be the iacv or air in the coolant..
