When I removed the under tray to adjust the lower CP (wasn't quite seated right after the ETS intercooler install) before installing my new ER CP and Tial BOV I found this


Looked like it was oil, fairly recent, but not too much. Any idea what it would be from given the location of the splatter on the under tray (maybe mid to aft part of the motor passenger side)?

The ER CP install was pretty smooth, but it seems just a little loose where it connects to the throttle body? The O-ring was undamaged and seated properly and the c-clip also was undamaged and nice and tight. I don't think that the CP is going anywhere given with how nicely its bolted down to the bracket, but anyone run in to this issue as well?

Doesn't seem like the BOV is all that loud, but I knew that it was quieter than the Synapse or HKS - really like how it looks though! A little bling-bling for the engine bay!

It's not the fact that it's bad, but yes we do get oil leaks. Clean everything really good, run it for the day, jack it back up see if you can fine the leak. oil leaks can travel so it's hard to say where comes from.

I just had the oil filter housing gasket Replaced at 59K. CPO covered it.

Yes it does feel loose so does mine, but no issues so far. Yes the TiAL is a quiet one, more of a Natural Swoosh sound.

oil filter housing gasket....usually

Could be anything or nothing.

Just take a look under the car. Sometimes the rear turbo inlet has a little oil, nothing to call home about.

Other times it could be leaking oil pan, oil filter gasket, or the turbo's themselves.

The car is sitting in the garage with the under tray off so we'll see if there is any change. I'll give it a good look underneath when I put it back on.

No further dripping on the floor while the car sat in the garage with the undertray off. Oil level is staying constant at "Max". Looks like maybe a little oil around the bolts on the oil pan - seal going? Appears to be pretty minimal so I'll just keep an eye on it.

In my original post I asked does anyone with an ER CP has an every-so-slightly loose connection at the throttle body? The o-ring from the OEM CP looked to be in good condition and seated in the ER CP just fine. The c-clip is also in good shape, so just wondering if the little bit of play in the connection is normal? Thanks.

Yes. Totally normal so far as I can tell, my ER chargepipe has a very small amount of play right at the TB connection. I’ve been putting minimum 17psi through it since fall with zero issues or quantifiable boost leaks. I was a bit worried at first, but after however many WOT pulls over the last several months it’s no longer a concern of mine. Also, I wouldn’t be too worried about that oil, unless the leak starts to spread or increase in volume, that looks like a pretty tiny amount of oil. These motors are leaky gals, my car smokes oil at every stop light and I’ve never had to add more than half a quart between oil changes.

Clean it up and put back and drive around and see if it comes back. If it does figure out where its coming from (measure from some point and then look up. Should be pretty obvious)

My guess is oil line to the rear turbo. Check for moisture at the cartridge (between the scrolls of the rear turbo).

Thanks, just the response I was hoping for.

Can't tell 100% from the picture, but it looks like there is oil pooled on your oil filter housing in the 3rd pic. I had the same problem. You will need to change the oil filter housing gasket and the thermostat gasket.

Totally did not notice that, but I'll take a look after work today.
