So there is oil all underneath my 96 turbo sedan. I have seen it dripping from at least two places. I have narrowed one leak down to the area around the turbo drain valve, on back of the block above where the oil pan bolts to the bottom of the block. Anyone know anything about this leak, or how to fix it?

The other spot is from the drivers side of the radiator. I removed the plastic cover from underneath the radiator and there was a substantial amount of oil in the trough on it, mostly crusted but there was some fresh stuff in there, maybe a tablespoon or so. I can't figure out where this oil is coming from...any hints?

Thanks!

 

1. There is an o-ring that goes bad that is on the turbo return pipe in the block. You need to remove the clamp between the return pipe and the oil line. Then remove the screws holding the return pipe to the turbo. Then work the pipe out.
Install a new o-ring and install and put in a new gasket between the pipe and turbo.Tighten screws and done.

2. Sounds like the oil cooler lines are leaking very common.
The oil cooler lines go from the radiator to the front bottom of the motor.

 

So I'm pretty sure that it is the turbo drain line that is leaking, but didn't have the parts yet so it did not get fixed this weekend. But after I spent the weekend changing my spark plugs, changing the oil in a 4 runner, and cleaning my motor quite a bit, I noticed white smoke coming from my exhaust late Sunday night. There are white streaks in my oil and I've been told this means that I blew a head gasket. Is this true? I think my coolant level has diminished quite a bit as well.

 

Do what's called a block test that will tell you if the headgasket is bad.
