Trouble shoot blue smoke

[John 550]

A friends car with a 428 has just developed a problem .
after it warms up for a few minites , drives for a half mile ,
blue smoke comes from the drivers side pipe for ten seconds
then stops smoking , all seems fine . This happended twice now
in a row at start up .
About 8000 miles on a Pro bult thats five years , Edelbrock heads ,
typical cobra motor , driven lightly for years , then a quick trip to the track
hit the limmiter a few times , so what do you think ?



Thank you !

I am guessing oil is getting burned on that side of the motor, either from a leaky intake gasket around one of the intake ports, so the engine can suck oil from the lifter galley; or maybe just bad valve stem seals. This is only a guess.

Had the exact same problem on my very first 428 FE; only came out of one sidepipe exactly 29 seconds after idle at a stoplight. Weird resolution on mine! It would clear out after I took off. Seemed just like what Mr. Fixit said, and then I kept searching and searching... 1) Checked for bad valve-stem seals, No.... 2) Intake gasket and vacuum leak checks, No... 3) Had intake angle surfaced to match heads perfectly, No... 4) Checked for bad/stuck/clogged PCV-valve to carb from valvecover, No... Engine had good compression too... 5) Tore engine apart... and found out the wrong rod bearing clearances & rod bearing side clearances had been set up by previous engine builder. Oil was slinging up on one side into the cylinders from the bottom side, later the other side too... the oil rings could not keep away enough oil at long idles for some reason. Hopefully yours will just be an intake manifold gasket or valve-stem seal as Mr. Fixit suggested. Good Luck.
