Toyota Repair: 1993 Camry LE, toyota camry, oil lines

Question
I have a 1993 Toyota Camry LE w/2200  16 valve. My question is...where exactly is the cam seal located on this model?
I had my timing belt & water pump replaced recently, & within days had begun losing oil under the passenger side with large puddles of oil, not to mention oil lines up & down the road while driving.
The mechanic that replaced my timing belt & water pump tells me that the cam seal needs replacing, & that it's located "on the other side."
I've called other mechanics for input, some say this car could have 2 cam seals, others say it could be located on one sie or another.
Others ask me if I mean to say the "o" ring.
I hope you can simply tell me where this seal leak is for the cam seal, & whether or not the cam seal was accessed in the taking apart to get to the timing belt/water pump.
Would the VIN# be of any help?

Answer
The 4 cylinder engine has only one camshaft seal and it's located on the front of the engine, the camshaft gear has to be removed to replace the seal. There is also a crankshft oil seal that can leak, the mechanic that replaced the water pump and timing belt should have recommended to you that these seals should be replaced at the same time when the timing belt was replaced.
