Oil Leaks

[pwoffutt]

I just purchased a 94 SR5 3.0L V6 with a pretty heavy oil leak. I have already replaced the frt main seal, rear main seal and both valve cover gaskets. It had so much oil and grit on the engine it was a little hard to tell where the leak or leaks were coming from. With the engine a little cleaner after all that work it now appears to be coming from the left camshaft seal. Is this something someone else experienced? If so, did it turn out to be the cam seal or something else? I appericate any feed back and thanks.
