hello, please read my dilema.. i have a 95 es300 that started leaking a few drops of oil on my garage floor. i finally took it in and we put it on the hoist and started it and found the oil dripping out of the bellhousing area. the next week i had a rear main seal installed. it seemed to stop for about 5 days and then started dripping again. we then thought it might be the pcv clogged and pressurizing the crankcase. we replaced the valve, cleaned the tube and the manifold nipple. it seemed to go away a couple of days and started again. i then pulled the valve out of its mount in the block and drove it a day and no change. last week it started leaving a big puddle of oil on the floor about 6-8 inches in dia. and smoking real bad from hitting the exaust. it would use a 1/2 qt on a 60mi. trip. as of tonight it sits on a lift with the tranny out. used fuorescent dye with the blacklight but the flywheel flings it around so much couldnt find a good source. our last ditch effort.. we cleaned the rear of the engineand filled the crankcase up with tranny oil hoping to find a static leak in the morning. if any of you are lexus techs or have friends that are lexus or toyota techs could you ask them about my problem? i would be very grateful. its getting very expensive at this point.. thanks!!
