WELL LET ME START AT THE BEGINNING AGAIN. 351 W BUILT IN A 67 PROSTREET COUPE. LOW MILES ON BUILD. OIL PRESURE WAS LOW. PULLED THE INTAKE GETTING READY TO PULL THE MOTOR AND FOUND A PUSH ROD SNAPPED IN HALF AND LIFTER HAD SHOT OUT. SO TO BE SAFE I PUT IN NEW CAM AND LIFTERS. WENT TO LONGER PUSHRODS TO FIX THIS PROBLEM IN THE FUTURE. I HAVE ONE OF THE BEST FORD MOTOR GUYS IN THIS AREA HELPING ME. WE FINISHED UP AND WHILE BREAKING IN THE NEW CAM HE BEGAN ADJUSTING THE CARB. 10 MINS IN SMOKE STARTS, BURNING OIL SMOKE. THE CAR NEVER BURN OIL AT ALL BEFORE. ANYWAY HE SAYS HE THINKS THE CARB IS LOADING UP. SO I REPLACE THE JETS FROM 80'S ALL THE WAY AROUND TO 68 FRONT AND 76 REAR.
CAR DOES SEEM TO RUN BETTER, DOESNT SEAM TO LOAD UP LIKE BEFORE. BUT AFTER GETING WARM THE SMOKE STARTS AGAIN. I DROVE THE CAR AND IT RUNS LIKE A STRIPED APE. VERY STRONG BREAKING THE 15X15'S LOOSE AT 50 MPH! BUT THE SMOKE IS A KILLER. ANYONE HAVE ANY IDEAS? IS THIS GUY SETTING UP ANOTHER JOB?COULD HIS VALVE ADJUSTMENT BEEN OFF? PLEASE ANY IDEAS WELCOME!!!!! HELP PLEASE

Blue smoke is oil smoke. Black is gas.
Just a wild guess... Valve guide wear?
Can you isolate smoke to just one side or both?
Smoke on acceleration, deceleration, or both?

Please type in lower case... makes it easier to read.

RUSS, IT SEAMS TO BE BOTH. AND ITS A WHITE/BLUE SMOKE. WHAT WOULD CAUSE THIS IN THE HEAD WHEN THEY DIDNT EVEN COME OFF WITH THE REPAIR? AND WHY IS IT ONLY AFTER 10 MINUTES OR SO?
THANKS A TON

White is coolent.

Blue and white smoke after a ten minute warm up... sounds like something cracked. This may have just gone over my head. CaMachinist seems the next step.

You might try to isolate the cylinder with the crack (if there is one) with a leak down test, pulling plug wires and checking for smoke, or just just comparing plugs for the odd one.

Any further news on the blue and white smoke? Have you looked at the plugs?
