I just bought a 93 with 34000 on the odo.. Completely stock I cked the car out well (I thought) Great compression. great turbo test 10 8 10 .. great idle.. Oil and water looked clean the only problem i found was an oil leak that seem to be under the turbos... I drove the car home 600mi and there is now milky oil on the oil filler cap and the car ate about a quart of oil.. Is the motor blown?? or is there some other way to get water in the oil???

 

some milky in the oil cap is ok but you probably have a leaky oil pan or oil return line on the turbos. where are you located ??? only take it to a rotary shop familar with FD's

 

The white stuff in the oil filler tube is just condensation. It's not a big deal. It usually occurs with alot of stop and go driving.
