My s70 is still leaking oil and its getting old and tired of buying oil. I don't really smell the oil while driving and when i take the sparkplug cover that little piece of black metal covering the wires and plugs it is has oil in it. Talked to my friends dad tonight and he said it probably wasn't a blown head gasket it was something to with the valve cover, or a valve cover gasket... which isn't to bad better news so to say lol. But please i need some input on this and how much it will cost me and everything that anyone can contribute can help me fix my oil leak can't afford buying oil every week.

 

/bump Can someones please help me out! URGENT!

 

Is it dripping on the ground?
Turbo or Non?
Bottom of motor wet?
The Cam covers rarely leak unless someone has been in there before.

 

my car is turbo and is dripping on the ground. motor isn't wet so to say

 

There is alot of places it can be leaking from the turbo return line o-ring could be bad.
Could be oil cooler lines if it is a 98. Could be a rear main seal. Could be cam seals leaking.

You need to clean it up good and run it then look for the leak.

 

Is it a cheap price to fix those things?

 

Some are cheap some are expensive. The rear main the tranny has to be removed.
The turbo oil return line is pretty cheap.

 

Come to think about it... It seems likeits leaking around where the turbo is located back behind the motor.

 

Could be a simple fix then.

 

I have similar thing going on. I don't know if it is appropriate to post it in this thread or I should open a new thread. I am just gonna post it here for now and move it later if it is better.

Mine is 99 S70 T5, and 94000 miles on it. I have driven around 1,300 miles since the last oil change. Yesterday, I had to refill 1/3 qt of engine oil because it was lower than the low mark. The previous owner knew about this and he did the same thing, just checked the oil level time to time and added some when it was low.
It does not drip oil on the floor. I usually find that it is low after flooring the gas hard. I know many people talks about rear main seal or turbo return line as potential leaking points. But I am new and I don't know where exactly the rear main seal is. when I looked under, I saw something like what you guys describe as the turbo oil return line. The upper end (with two nuts) seemed clean but the lower end was soaked. I also noticed that the thing that I believe it is turbocharger is soaked with oil. I could not see further but I suspect the oil may be coming from higher location. Should I be worried about this?
If I am going to replace turbo return line o-ring and seal, am I supposed to do this after drain the oil? Can I also spray lots of brake cleaner around turbo to clean and see if leaks come back somewhere? I already sprayed some on oil pan where I could easily reach, but just to make sure if it is safe.

 

Obviously coming from the turbo. I'd take off the intake pipe and see if you have oil in the turbo. If you do, then it could be turbo seals, or a bad PCV sending too much oil through the hoses and into the intake pipe. Make sure all of the turbo's copper crush washers are there. I would replace the return line o-ring for sure. No you don't need to drain oil.

 

Clean it up and take it for a drive boosting it some. Then recheck it. Might be turbo return line o-ring or rear cam seals.

 

Ok, sounds like I have enough project for the weekend. thanks for the advices.
