might have killed my Camaro
 

My 69 Camaro has a stock (rebuilt) 2000 LS1 with heads/cam/injector and upgrades like the oil pump.

Every since I did the 102 LSXr intake and coil relocation it has developed a nasty blue cloud on start up. I assume the valve stem seals dried up coincidently.

Anyway, it is on the back burner - but I've noticed I'm leaving a nice cloud now not only at start up - but while cruising.

So, fast forward today. I needed to drive the car to work as my other vehicle is down. Rolling in (25 mile open straight line cruise) at 65, I can hear a LOT of noise out of the engine. I'm thinking...I have a serious header leak. Then I look at the oil gauge...ZERO

I eased it up the road to a Mobile gas station - and found at least two quarts low! Paid $8 a quart and it has oil pressure again. I am clearly burning more than I thought!

So...hoping I didn't screw it up. The ticking/knocking got quite after that. Usually only run Royal Purple - but had to put valvoline in it this morning.

:headspin:

That blows man! Time to go big time!! LoL!

what are you running for a PCV system?

Compression and leak down test time.

Running a stock pcv system on a slightly modified hose since the valve covers are not stock. Drove home okay. No odd noises and the needle back where it belongs.

I am slap in the middle of taking the frame out of our 2014 silverado 4x4. That is a long story. Anyway hope to get the cab off today and by the end of next week have it running again. The. I will have some time to check out the camaro. I would bet my pcv is contributing but it is all hooked up.

Hopefully, the engine is ok and it's a minor repair. Sorry for your troubles.

You just shortened its life....

My first guess is the intake manifold "upgrade" has you running pig fat - and you've glazed the cylinder walls - so now the rings aren't working and you're blowing oil past them. It was noticeable at start up because it's even fatter (richer) on cold start up.

Start planning for a rebuild - motors aren't self-healing.

I would concur with this assessment.

Are you running a LS6 valley tray with the breather vent? If not, I would invest in one after the rebuild. It works much, much better than the early LS1 valve cover PCV system.

Reason I asked, I bought a used 99 Firebird and I got it cheap cause he had the same symptoms you are having. He assumed it was the engine. Blue smoke 1 qt oil every 900 miles. I was gonna do an engine swap so I didn't care.

Did an oil change and when I pulled the air boot to clean the throttle body I pulled a bunch of oil out of it. The throttle body was caked with oil residue. So I pulled the intake and tipped it up for a few hours and got almost a half quart out of it.

Cleaned the intake out, changed the cracked PCV hoses, changed the oil and I never had an issue after that. Held oil till 3000 miles, no smoke and oil consumption issues. I ended up selling the car cause it ran good and a huge profit never hurt anyone.

Ok I have to ask ^^^^^ why are you taking the frame out of your 2014 truck??

Just swapping the intake usually doesn't effect fuel trims/air fuel ratio much.

Even if it did, as long as the o2's were functional it would at least still run at stoich under closed loop if it is within the range of the fuel trims. (and unless there are other problems it would be).
