Must change oil on dry sump Corvettes at 500 miles

That was all BS I had one, what BMW ended up doing was replacing the rod bearings and giving a 100,000 mile warranty on the engines. The oil excuse just didn't play they did change from 5W 30 to 10 W 60 Castrol but engines were still blowing up. Then they tried to say that the motors wernt broken in properly that was BS also bottom line it was a bearing problem.Carl

Ok, GM has released their bulletin on this issue and it has to do with an oil foaming issue during breakin. The bulletin is posted on the other thread having to do with early oil changes. I would have posted it here but not sure how to do that. Someone with some basic skill can get it on here. Anyway its official by GM. It applies only to 2014/2015 dry sump engines and you will get 5 oil changes during the 24,000 mile/2 year time frame.

the rest of the bulletin is blah blah blah but heres the operative paragraph:
Some 2014/2015 Z51 and Z06 Corvettes may experience a condition that leads to oil leaking out from the air cleaner assembly. This condition may be caused by running the engine continuously at a high engine speed with the first factory fill oil, resulting in silicone sealants in the engine’s gaskets degrading the oil’s anti-foaming agents. The oil foam has no effect on the engine’s durability.'

For new Z51 or Z06 Corvette owners...
2014/2015 Z51 and Z06 Corvettes – Additional Required Maintenance..

2014/2015 Z51 and Z06 Corvettes – Additional Required Maintenance
The following message only applies to dry sump Corvettes that have not had their first oil change performed.
Some 2014/2015 Z51 and Z06 Corvettes may experience a condition that leads to oil leaking out from the air cleaner assembly. This condition may be caused by running the engine continuously at a high engine speed with the first factory fill oil, resulting in silicone sealants in the engine’s gaskets degrading the oil’s anti-foaming agents. The oil foam has no effect on the engine’s durability.
Effective Immediately:
GM is changing the required maintenance schedule for all 2014/2015 Z51 and Z06 Corvettes equipped with dry sump systems. The new schedule will require the oil/filter be changed immediately after the break-in period, which occurs after the first 500 miles of operation. Once the break-in oil change is performed and the Oil Life Monitoring system is reset, customers should follow the Oil Life Monitoring system for all future oil change needs.
The 2nd printing of the 2015 Owner Manuals is being updated with this change. These manuals will not be in the glove box material until January 2015. For vehicles produced before this change, and for all vehicles going forward, it is important to notify the customers that a change has been made, and they will need to have the vehicle’s oil changed after the break-in period. Copies of the new maintenance grid will be available on GMPROGRAMINFO.com, under Chevrolet, Resources.
As you are aware, all 2014/2015 Corvettes come with Chevrolet Complete Care which covers 2 years/24,000 miles of select required maintenance. Previously, up to 4 service events were allowed under the program guidelines in the 2-year/24,000-mile period. With the change in the maintenance schedule being effective immediately, an additional oil change allowance will be added to 2014/2015 Z51 and Z06 Corvettes, increasing the amount of coverage to 2 years/24,000 miles, up to 5 service events.
Please make sure all dealership personnel are aware of this change.

What is considered "High Engine Speed"? I was running 80 MPH for most of a 800 mile trip to Cincinnati. It took 12 hours and by the time I got there I was trailing oil up the driveway! Is that high speed? The RPMs sure didn't seem to be very high as I was in 6th for the run.
I had my refill from the dealer after I got back to Jacksonville so I guess I'm exempt from this TSB.
Oil foam huh?

Oil out of the air cleaner? Really?
I think that maybe they also now understand what floats around the oil in these new engines.
I changed my LS3 oil at 500, 1500 and 3,000.
Took a lot of crap for it too.
Wish I'd kept pictures of what came off the magnetic plug I'd installed.
(my kid lost the camera with the pics on it) :-(
First change had smaller and larger metal particles.
Second and third had a pasty grey substance that was full of tiny metal particles. Felt like sandpaper between the fingers.
Next one at around 6,000 was pretty clear, but still some metal.
These engines shed a lot of metal in their break-in.
Regardless of the B.S. about quality of machining, and new TSB I'd err on the side of caution anyway.

80 mph with a standard shift Z51 is ~2000 rpm. Not high considering the 6600 rpm red line or what you’d run when tracking! However considering this GM statement:“This condition may be caused by running the engine continuously at a high engine speed with the first factory fill oil, resulting in silicone sealants in the engine’s gaskets degrading the oil’s anti-foaming agents. The oil foam has no effect on the engine’s durability.”
..is the issue the high rpm with the crank and rods beating oil as it escapes from the bearing journals before it is picked up and sent to the dry sump tank the issue? Or is it the sustained engine heat from traveling 800 miles at 2000 rpm that causes the silicone sealant to degrade the oil’s anti-foaming agents? Have to believe GM looked at the oil dripping issue and has some evidence this is at least a partial fix.
I have not had a problem but also have made no long trips! After my early oil change I have kept the dry sump a ½ quart low. Think I’ll continue!

They've had the car a week now and tell me its a bad flywheel in the transmission and I'll be lucky to get the car back in time for Thanksgiving. The car is in pieces on a lift as they've basically disassembled the car. I cannot tell you how frustrated I am as this sucks!!!
