2006 Chevy Aveo manual tranny. Major leak from a pan behind the oil pan on drivers side. Is not oil but gear oil. Pan has several bolts on it, does anyone know what the pan is?


The manual transmission does have an oil pan. Try tightening the pan bolts to see if any have come loose causing the leak

Oil leak passenger side 300 turbo sedan, some on front passenger side wheel. Never lost oil pressure, but dipstick showed very little oil in crankcase on immediate after-run check. Have not started...


Add about 2.5-quarts of new engine oil to the engine.
Remove the passenger-side wheel, and support the car on jack-stands.
Start the engine and look for oil leak.
Chances are leaks are coming from failed oil-pan gasket or the drain-plug.
The head-cover gasket could be failing as well..

300 zx twin turbo sucked water up in through air intake..what now


Easiest way to get water out of the motor is to remove the head and then manually remove the water from the pistons / head.

Remove the head and spray it with brake cleaner, let it dry first
and then be sure to put synthetic motor oil (same weight as before) over the dry metal to help lubricate it again. (The brake cleaner will take out the water/dirt and clean it very easily)

After that, while the head is prepped to go back on, using a cloth that doesnt have lint, **** up all the **** out of the cylinders - like the water / shards of metal / etc.


This is a very tedious task, especially with a 300zx because like you said, theres no working room.
Might wanna check your turbo for possible moisture (It can make it rust and become faulty)
