oil leak, drivers side, front of engine - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

The most common area for any engine to leak oil is the area where TCC, Head, and block meet. With the differences in the metal expansion/retraction due to heat the sealant used will eventually crack. The crack will allow small amounts of oil to leak. There really isn't a good fix for it once it starts other than removing the TCC and cleaning the intersection well. Reapply sealant and allow it to cure fully.

its not the TCC, its coming from below the top of the engine. the only part that has oil on it is the front, and with the stock intake its hard to see where exactly its coming from

Add me to the list as well mine is on the passenger side. Took it to a toyota dealer they said they are not sure where it's coming from and told me I have to take it to a scion dealership. I am waiting to get an appointment to take it in.

You can see small cracks on my engine in the picture, do you think that's the problem?

No. That is roughness from the casting process when they make the block, it's not worth the OEM's time to prep every block so it looks pretty.

Oh sounds reasonable. I thought they were cracks when I was cleaning the leak today

Let me know if anyone makes it to the dealership before me what they find out. I'm not looking to have an engine fire from an oil leak. I have seen to many people say it's just a little oil and then a few weeks later post a picture of a ball of flames because a small leak turned into a big leak.

I'm curious about this as well I just hit 41k and I've been having a burning smell come through the vents a lot lately. Will be doing a thorough inspection of the engine bay.

you can run your hand underneath the chain cover to feel for leaks..

I noticed a leak in the same location on my car while inspecting it recently. Car has 22k miles on it ( 8k boosted ). Bought 5/31/2012. Can't do much about it for now. Will keep an eye on it and my oil levels for the near future.
