Check out this video and tell me what you think.

What is causing the smoke on the deceleration? Could this possibly be worn valve guides?

They are Brodix heads with less than 700 miles on them.

The car was idling for 5min. As you can see it was not smoking much at all on idle but after acceleration, excessive smoke started to come out of the exhaust.

-Thanks

Pull your plugs and look at them. I have Brodix RR on my 427 that I had all the intake valve guides go bad. The plugs were oily and had alot of carbon build up on them.
Mine was due to improper valve train geometry. The rocker was riding front to rear on the valve stem.

On a bud's 69 Camaro, his RR's did not come with exhaust seals, causing excessive smoking.

my has exhust seals do you all see the video whats causing this smoke ?

do you run PCV valve.

didnt you just have heads repaired because of worn valve guides if its same again you must have some serious valvetrain geometry issues.

yes just had them done, yes am runing a pcv.

yes just had them done, yes am runing a pcv.

pcv might pull some oil mist in to your intake. leave pcv off and try again.

yes it did help. just running a breather . also had a tech look at it he said it was fuel he claims he can smell the fuel from the smoke

My valve guides need to get re-done as well. I pulled the PCV and placed a breather on mine and the smoke calm down quite a bit. 700 Miles on my motor (049 Heads re-done with motor).


FIrst half of Video shows before and then after, Definitely an improvement without PCV

i think i got the answer to my smoke issue i was opening the secondary of my carb which was dumping all that fuel with no load. a quick thrust on the peddle.
