My good friend is a mechanic at the biggest Lexus dealer down here in south Florida, so I did a trade off with him by putting in a new kitchen for him, he maintains my car for free. I am now in need of the 90k mile service for my 1999 gs300. I am getting the water pump, timing belt, fluids, sparkies, and some seal he said might end up dripping oil if we dont replace it and since hes in there he will do it. If there is anything else I should have done pleeeease let me know. I am interested in keeping this car as long as it will run. So If anyone can drop some knowledge for the newbie I would appreciate it.

 

He's only going to do one seal? Im assuming he talking about the front main seal. Have him replace both cam seals also, they are easy, and right there. Might as well replace the one idler under there too.
