Default Engine smokin

Went for a cruise in car today, when blue smoke started coming out of passenger tailpipe. I had the engine rebuilt about 200 miles (and 2 years) ago. The smoke has to be oil by the smell. The car was down about a pint in a 20 mile trip. Car also seemed to be ideling higher after. The engine has been using oil since rebuild, but nothin like this. Car is 66 vette with 427. The engine is bored over, and new pistons were put in. Any suggestions on what it could be would help. CAr has been sitting all year because of brake problems, had them fixed last week and put new tires on today when car went down again :mad Anyone want to buy a car? :lol:

Sounds like you may have blown an intake gasket, on one of the runners, and it is ingesting crank case air/oil. This would explain the high idle (vac leak) and the oil consumption being bank sensitive.

Did you take out the plugs on the passenger side and check them for oil? If not this is the first place I would look. Like the previous post said it could be as simple as a gasket..... :yesnod: or ..... :crazy:

Good Luck.... :cheers:

You can spray carb cleaner around the intake gasket area and the carb base to check for a vac leak and also around the vac lines to find the possible leak. also your engine only has 200 miles on it, it isn't even broken in yet.

LENNY66,
I had a rocker stud break clean in half on my 67 rectangular port heads. It was cracked within the space under the adjusting nut so it didn't SWARM on me going down the road. Luckily I came across it while adjusting the valves. The studs screw out, simple fix. Someday when I rebuild I'm putting all new ones in.
