There is an oil leak in my Camry (slow drip) but it seems to happen only when it morning ..i.e. engine is cold overnight. Once I drive the car to work (30-45 minutes) it does not leak during the day. This tells me this is from a seal which seems to expand when the engine is hot and contracts when it is cold.
My mechanic is willing to help me .. but has told me this may be difficult to fix as he may have to 'open' the engine ... and will cost a lot. He is completely trustworthy and has helped me in the past.
Car has 190K miles (80K on rebuilt engine).
Any ideas ? Will adding higher viscosity oil help stem this ? I'm looking for cheaper alternatives .. have already pumped more money than I should have in this car ($800 recently, replacing steering rack, front brakes, rotors)
Thanks
