Default Need Help: 2011 STI Oil Leak Diagnosis(Might Be Oil Pump)

So I'll do my best to keep this short. I bought a 2011 STI nearly a month ago and realized that it was dripping oil. I didn't think much of it but since these cars have so many issues with oil I figured I'll get it to a shop ASAP. The car has an IAG Stage 1 Plus short block in it that was installed roughly 30,000 km(18,000 miles) ago. I decided I should take it to the same shop that did the engine install. They took a quick look at it and realized that the leak was coming from behind the timing cover so they would have to get deeper into it to narrow it down.

They couldn't get around to it until last week but according to them the leak seems to be coming from where the oil pump is located so the tech decided to remove the oil pump, install a new crank seal, reseal the oil pump and put it back on. Unfortunately when they put it all back together and started the car up it was still leaking the same amount from that area. The car has been parked since then until they get time to look at it again but I've spoken to the service manager and he mentioned the possibility of a cracked block.

I just wanted to post here to see if anyone has experienced anything similar or had any ideas as to what it could be. Thanks.

Well lets see if we can help. First of all what do you mean

If you do things right and change things when they are suppose to be changed, you should not have oil leaks.

Second, who did the install? Are they IAG Certified Engine Installers? I ask because IAG only honers their eng warranty if it was installed by a IAG certified shops. "IAG warranty of 2-Years/24,000-Miles if installed by an IAG Certified Engine Installer".

If they are a certified installer then have them fix it under warranty.

Third, what do you mean

They have your car they should be working on it.

And fourth, what evidence do they have to say the block is cracked? Where is it cracked? Post the pics of the leak so we can see. Or ask the shop to send you some pictures.

What I meant by the oil issues was that I was warned about never running these cars low on oil and always keep an eye on oil pressure. So I bought one that had a recently rebuilt motor and an aftermarket oil pressure gauge hoping that I wouldn't have these types of issues. I also checked the oil maybe four times in the 24 hour period that I actually had the car (between me picking up the car and then dropping it off to the shop). I wanted to make sure the leak wouldn't run the oil too low.

The shop is definitely IAG certified, they are the biggest Subaru specialist shop in the area. They did mention that IF the issue is block related then IAG would have to inspect the motor and decide whether or not this was an error on their end or the end user.

As for the third point, that's the part that's becoming frustrating for me which is why I decided to maybe try to get some advice from some of you guys who may have experienced something similar. The shop says they don't have the time to look at the car since the appointment that I booked is done so now they'll need a window to open up just so they can look at it again. I'm not used to shops doing things this way but I thought maybe because it's such a niche market, these guys can get away with doing things like this.

As of right now there is no evidence that the block is cracked. What happened was I decided to drop by one day and just talk to the service manager about why the work was done but the car was still leaking. He had explained to me that the leak seemed to be coming out from behind the oil pump so they tried replacing the crank seal and resealing the oil pump. Now that it is still leaking he said worst case scenario it could be a cracked block or a weird spot in the casting of the block which is allowing oil to get out.

I can definitely ask for pictures but they probably wouldn't be able to get them until they open the car back up anyway.

Well lets hope for worst case scenario so they can change it out under warranty. Ask them when is the next available appointment and book it. I speak from experience back in the day when i just started this game and the shops had my cars for months. If the car drives and not to far from home, just take it back. In my case, the longer the car was in the shop the more and more issues came up, plus more scratches an dents.

Yeah I was worried about the same thing, I didn't want to get the car back all dinged up. I guess I'll go get it for now, hopefully get an appointment booked.

Well I got charged $700 for an attempted repair and an oil change on a car that's leaking oil. They also didn't have another appointment until the end of January so I'm going to have a friend take a look at it to see if he can spot an oil leak or a defect in the block and go from there. I'll keep the thread updated just in case someone runs into a similar issue in the future.

$700 for "attempted repair"? What was included in that "attempt"? Did they swap parts, or install new parts? Oil change should be around $50 so $650 for what?

Yup, I'm pretty damn upset about it. All they did was remove the oil pump, replaced the crank seal and the oil pump o ring. Resealed the oil pump that was already on there. Put it all back together and did an oil change. Mind you the bill was $700 Canadian currency but still pretty ridiculous in my opinion. I was charged for 5.5 hours of labor, $8 for an oil filter, $50 for oil and $14.27 for parts.

Well my friend and I got a chance to open it up and take a look at it, it turns out its one of the case bolts on the driver's side of the engine that's leaking. He removed the bolt and we noticed it just had a regular washer on it. I just have two questions, are these bolts supposed to have oil on the other side? I want to make sure there isn't any internal damage or leaking going on. My second question is, what kind of washer/sealant is supposed to be on this bolt?

Is it the case bolt under the oil pump? Washer is fine, there isn't oil behind it, but the case halves should have rtv/sealant of some kind to prevent the oil from getting through there.

No it wasn't under the oil pump, I believe it's the one between the oil pump and the water pump. I circled them in red but I'll double check with my friend to confirm which one it is. I just need to get the replacement parts tomorrow so I want to make sure I get the right stuff.

EDIT: So I just spoke to my friend, it's the bolt that's circled in red at the top. So I guess I'm just curious now, are any of these bolts supposed to seal oil in?

the bolts don't seal oil, but the pump should be sealed to the block...
