Ok... the patient is an 87 740ti w/ 219k, bought the car at 216k and minus a power steering belt it has been problem free. Ok maybe not problem free, the problems I know about are: Oil leak, dont know where it is coming from and i cant find it, coolant leak? I topped up the coolant right after i bought it at 216k and yesterday i checked it and added about 20 oz. The smell is this, under heavy acceleration I notice a strong "fish-like" odor coming through the vents when the heat is on, after a few minutes or a stick of incense it usually dissipates rather quickly. Any ideas on what might be causing this smell... and it is only under very heavy acceleration. ANOTHER QUESTION: when idling at a stop or in a drive-thru i notice another different smell. Its somewhat like when you spill oil on the head and it burns .... i think this might be due to the oil leaking onto something hot? any ideas here.... YET ANOTHER QUESTION.... what places should i check for oil leakage, i know its not the drain plug or filter ... where else should I check? ANOTHER question: im driving around today when i notice steam coming from around the instrument cluster but it subsided when i turned off the heat, i also noticed it yesterday coming from around the passenger side floor, again any suggestions?.... i know the # of questions posed may be daunting but any help is much appreciated...
