Smoke exhaust V6 camaro

[2013ZL1FUN]

Fred Flintstone oil has the same stuff in it that George Jettson oil has! Just fewer impurities, so it would look the same burning. Do you really think a V6 Camaro has a aftermarket catch can on it?

120 or 130 Psi


I saw an ad where someone was selling an LFX, and his tested PSI was
120/130 on the cylinders, except 3 and 5, which were bad. Low mile engine too.

The PCV system is where most of the oil loss is, it's a known issue, and as
I said, there is a valve cover gasket that fixes it. Not sure if they were
updated later at the factory. Still, yours is way more than anything I
have ever read about.

Low compression is not NO compression. When it gets low enough, you
will feel the miss, and lack of power.

Yes. Mine does. The blow back is real, and engines are engines.

Here is the issue..... https://youtu.be/CePGNsAkcYQ.... Oil not draining out of baffle in valve cover and line from intake to pvc is su king it out. I plugged the line to intake and vented pvc and to more smoke or lost oil. Been driving it and problems with anything so should be good till I get new valve covers and drill them out and get them powder coated and swapped out.

Except that's a V8, and not V6. The valve covers between the two are
not the same.



The V6 reason is totally different. There is no baffle at all on the RH bank
valve cover, where the PCV is, it's a wide open pocket. GM updated the
valve cover to block the entire area off, with only three ~8th" holes in the
block off to reduce the blow-by.

Here is one fix, for oil leaks:

2010 - 2011, and early 2012.

Here is the open pocket explanation, FIX, and why the chains fail:
