Rear Main Seal Leaking on Engine - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hey guys, new to the web site but just wanted to know if any of yall have noticed if your rear main seal was leaking? I change my oil myself and have noticed from about the 5th oil change that there was oil stains at the back of the block. Well yesterday when I was changing my oil I noticed that it has gotten really bad. Going in the shop Monday, car just hit 31,000 miles. And I always change it at 3-4 thousand miles.

Wlecome to the site. The ls3 and l99 v8 is notorious for leaking in this area. My l99 started leaking in that area with only 9,000 miles on it. Every time i would wipe it clean the leak would re- appear. I just got it taken care of a month ago. Come to find out it wasn't the rear main seal but the oil pan gasket and oil cooler gasket which is in the same area. Don't worry yourself too much, you drivetrain warranty is good for 100,000 miles which includes seals.

Mine was leaking too. I only have 3600 miles on mine.

Take a look at post# 2342 from Wild Thing. He had this issue and got a fix last week.

4 places to look (known issues on 5th gen Camaros)
Oil cooler line to the block
Oil Pan gasket (gasket/block porosity issue)
Rear Main Seal
Rear engine cover (gasket/block porosity issue)

Had the same problem with mine 6000 miles, engine oil pan leaking from rear corner. They replaced gasket and I got a free oil change.

I agree to an extent. These are new cars and new cars are not suppose to leak, specially oil! For the oil cooler and oil pan leak, I would get it fixed under warranty.

For the rear main and rear engine cover leak, I would just have it documented by the dealer and let it go if it is only dripping a drop every now and then. The reason I say this is because as we all know, half the time, it is a crap shoot with the dealer when it comes to intensive/intrusive work. Half the time, you realized u ended up trading a small problem for a bigger one that they caused. But if u have a puddle, definitely let them drop the tranny to get to the leak source.

Well just got car back from shop today and can say that it was a total waste of time. The guy told me last week to specificaly bring the car in at 8:00 this morning. Calls me around three saying that they didnt see anything out of the ordinary. WHAT? But wants to reschedule for May 24. I honestly dont even think that they looked at the car. When I was on the phone with him, he told me to go ahead and come pick the car up that he will have off the lift when I get there. 10 mins later and I'm there, they bring car around and I immediately notice that the car is super hot on the inside while driving home. Which in my opinion was a dead give away that they did not just take my car off of the lift, let alone even look at the car. Guess we'll try it again on the 24th.

I had a rear main seal leak at around 9,000 miles. The first dealer thought it was a oil pan gasket leak, it wasn't, the second dealer found it and fixed it. They told me the seal had a defect. I smell burnt oil every once in awhile, after higher RPM's, so I am not sure if it's back, it never leaked enough to drip to the ground, just alittle in between the engine and tranny. With a rear main, it seems the oil needs to be above the seal to seep out, so it does not leak when sitting idle, or low RPM's I would guess.
