Toyota Repair: follow-up to 3/1 92 Previa oil leak question, valve cover gasket, ring gasket

Question
Hi, Mr. Ritter. Thanks for your help. My original question was on
3/1/05, the '92 Previa with continued oil leak. I don't know
much about cars and I failed to mention that the dist-o-ring
gasket was replaced twice during this whole mess. Also an oil fill
tube side pan gasket was replaced early on. All this work was at
a non-toyota shop. What do you think now? The last repair was a
camshaft seal made with silicone and a new valve cover gasket.
Thanks again.

Answer
Something is not being done correctly, I think the best advice I can give you at this time is to have a toyota dealer check for the oil leak and diagnose it, the other shop was missing something or there would be no oil leak or the source of the leak was not diagnosed correctly.
