I recently described a problem with a used engine (not remanufactured) that was installed in my 97 tercel. Some fumes were entering the car when driving, even with the fan on recirculate (but more noticable when set to ventilate). Sometimes smelling like deisle fumes (burnt oil), somtimes like burnt rubber or burnt sugar, sometimes chemical-like, sometimes like dusty air, Most of the time, it is caustic enough to aggravate the eyes and lungs/throat.
My mechanic will change the valve seals and do a pressure test of the air heating system. Considering what he is doing, would it be simple to do a leak-down test? I read about the concept after a friend pointed it out, but I'm not sure if it would be easy to do in practice if one is going change the valve seals and pressure test the cooling system. It /seems/ straightforward, since the shop air is fed through the spark-plug port. I guess the engine doesn't need to be taken apart too much to do this?
