NO leaking under the car when running at idle and giving it some throttle but after a few runs today came home and noticed it was wet/sprayed around the TPS/Throttle body area.

After sitting for some time, noticed a 5"X5" puddle under that area.

Turbo or other oil hose in that area?

 

Bad o-rings in the throttle body. Under boost the oil in the airflow is getting blown out by the throttle shaft. It then drips down onto the turbo.

Search for some posts about replacing throttle body o-rings and you'll find a lister that sells a kit that contains everything you need to do the job.

OK cool.

But would it still leak when the car parked?

 

5"x5" puddle seems alittle big for a throttle body leak, unless they just blew and you had alot of oli in your intercooler pipes?

 

I did not notice when you mentioned a 5x5 inch puddle.....

Could be a leak from the upper balance shaft seal or housing/rear seal, or a turbo seal.

 

ouch!!!

Yea, after sitting in the garage all weekend there is an even bigger puddle now.

The turbo is only about 1 year old. LR Super series.

 

I am hoping one of the lines going to the turbo and not the turbo itself.

 

Yea, that sounds like a HUGE leak if you ask me! I have a SMALL leak that drips right on the exhaust from one of the turbo seals that I will be doing over winter, but even after sitting for over 2 weeks I get a puddle no bigger then a dime. If I drive it everyday I don't get a puddle.

 

Well, this morning, there was only a very small amount. I wiped up the original puddle to see for this morning and there was only maybe a few quarter sized leaks.

 

Ok, after a couple of days and normal driving with no boost, this morning was only a few drops.

I checked oil level and still ok. In all actuallyity, that "big puddle" was maybe 1/8-1/4 of a quart over 3 days. yea, still bad, but not as bad as it sounds.

So was it some wierd one time thing or just stopped due to not being on boost?

 

OK, it's not the motor or turbo.

Only a couple of oil lines in that area. the rest are all coolant. So either the hardline main passage to the turbo or 1 or 2 other hoses over there.

 

The seal from the turbo to the engine mount. It usually leaks there.

ok. Is that on the turbo itself?

All leaking/spray was well fwd of the turbo, i.e. going closer to the IC out pipe and such.

 

Well if it's spraying oil, then it's most likely leaking from the rubber connections at the intercooler to throttle body. Under boost oil will leak there if there is any. When is the last time you took your intercooler out and cleaned it? You'll be surprised at the amount of oil in that thing.

Also, take off the rubber connectors and clean them, the intercooler pipes, and everything else in that air path. I'll bet that the connectors are just letting the oil leak past the clamps, or that they have small cracks in them that open up under boost. Time to replace them and get new clamps.

BTW, you know that those clamps are not meant to be re-used, unless they are the ones with the screw and nut clamping (or t-bolt clamps).

If the oil is coming from the top, externally, then there are only a few places that it can come from. And the "growing puddle" when you park it may only be the oil finally making it to the ground after coating and pooling in the engine.
