Ok need help once more. The owner of a local goodyear who will be performing the timing belt job for my car (sounds like he's a timing belt expert) told me the rear camshaft seal needs to be replaced but not the front one. He says theres 2 camshaft seals , he also mentioned the front crankshaft seal. Now my question is, do both the cam and crank have 1 or 2 seals. I thought and from looking at diagrams my car had 1 camshaft seal and 1 crankshaft seal not a front and rear like he's saying...

Is he wrong or right? If is he's right than i'm confused as to which camshaft seal it is. Is it:

RUBBER, R. BACK SEAL

RUBBER, L. BACK SEAL

OIL SEAL (29X45X8)
