After putting on a full 3" tbe + o2 housing on my car , I'm getting this oil leak from a place that is unknown . It bothers me alot because I hate being able to locate a problem , anyway at first I thought it was the oil return line because oil was over the wastegate actuator , ending bracket on o2 housing where the dp bolts-up to , and a tad bit on the oil pan . So today I replaced the oil return line with new gaskets and used the same oil line after I had checked it being that it was leak-free . So as of now I'm all out of ideas and dont know what else to do , I just want my car to be running fine again as I'm tired of bumming a ride from classmates n friends to go to work and school.

 

Your car does not run? What part of the car is the leak coming from? Turbo? oil pan? intake manifold? head?

 

How big of a leak are we talking about here?

 

The car will run , but it will leak oil . The leak isn't bad , but very noticeable . As of the source of the leak I thought it was from the oil return line on the oil pan section , but after changing that out and starting up my car yesterday the leak still happened. The intake , manifold , and head shows no sign of leak . When the car leaks oil can be found on the actuator , bottom portion of o2 housing where the dp mates up to , and a tad bit on the lower portion of the oil pan. I did make sure my oil drain bolt was tight as well as my oil filter.

 

Did you take an extra bolt out of the block when replacing the O2 housing? You take a bolt out of the block for the bracket on the stock O2 housing, but you might have removed an extra one and not replaced it by mistake.

 

if ur sayin the oil leak is occuring from the turbo area, and u just replaced the 02 housing and tbe, my bet is one of the exhaust studs is loose from reinstallation....a couple of the studs basically play a plug to oil running through the engine....can u post pics of oiled area???

I do recall my friend removing the bracket bolt for the oem o2 housing , but he did replace it afterwards once the new o2 was installed . I'm guna go check it out

 

One of the 5 exhaust studs on the hotside was messed up but peeps told me it was no biggy as long as the other 4 bolts are nice and tight . Pics will be upload , thanks guys.

 

That's kind of iffy...under boost, there's a LOT of air flowing through that thing. I would try to take the stud out and replace it with a bolt if you can.

 

best way to find it, use brakecleaner clean the area around the turbo o2 housing block, lift the front of the car start go under and check it.

check studs on o2

another thing i just hope you didnt take the bolt out on the block under exhaust manifold, near the stock o2 bracket.

 

Is this bolt you speak of hold the oem o2 housing mounting bracket for the heatshield?

 

Pics are in : If you guys need better pics I can take them

 

Thank you sir , the problem was that my friend forgot to place the bolt under the exhaust manifold near the stock o2 bracket back in .

Pic of said missing bolt ( wrench is on it ) :

 

did you check the feed line to the turbo?

 

I did prior to seeing the leak , but it wasn't the feed line . The leak turned out from the block area which can be viewed from my previous post.
