1984 Other Toyota Models please give me your advice

with the enginge cold check the power sttering fluid level, coolant level and transmission level, make note of it.

drive it a while and get back to me if you low on any of the things i listed under the same conditions, engine cold.

either one can cause white smoke.

do you notice oil in the antifreeze?

take your dipstick for engine oil with the engine hot touch it on the exhaust manifold, does it boil, give off steam?? if so thers water in it.
