So a group of people were out for a leisurely drive up Angeles Crest today when a strange thing happened. After a series of high-g high-rpm turns, one of the cars momentarily lost power. Now, the quick thinking driver immediately jammed his clutch in, finished negotiating the corner he was in the middle of, then checked his rearview mirror. Blue smoke everywhere.
A few coasting turns later, and the driver had a few feet of clear road. He blipped the throttle while looking in the mirror - smoke, but the engine sounded good. Engaged 4th gear and made it to the next turnout (still smoking some) where he checked the oil level. 1 x below full - just like it was in the morning.
After a quick sniff of the smoke, and a look under the hood, the best guess was that a touch of oil made it into the throttle body. I've seen a few other posts here about light smoking in spirited driving, but haven't seen any mention of the momentary power loss - does that 'normally' come with it?
The driver finished the drive without further incident (geez, those black cars are fast!) and a 'rolling health check' indicated no problems. At any rate, monday the owner will be taking his ride to a dealer for a compression check - is there anything else he might want to talk to the SM about?

Thanks! - err, the driver thanks you...

You forgot to mention what turn.......? Wouldn't have been the infamous Carousel 270 degree unit just past Newcomb's Ranch Inn would it? I raced bikes on that highway for years.....so please..please tell me what turn did the problem appear?

P.S. I went through 2 351 Clevelands on the Carousel in my 1974 Pantera. Major G-Forces are possible there!!! Especially going away from Newcomb's towards the "Tunnels".

No it happened before the fork if you're coming up from the 210, I think a few turns before! The tunnels are on the right fork right? At least there's a tunnel on the right fork. And Newcomb's is on the right fork about 10 miles after Mount Wilson. Not too familiar with the area, but a couple of us got lost and went through one or two 270 degree turns

Fun day it was!

 

This was most likely the oil coming to the intake via the PCV? This occurance has been discussed on the board before. The malady is caused by high speed turns with enough centrifugal force allowing oil to get into the PCV and then on though the intake resulting in blue smoke.

 

Can you vent this to the atmosphere and plug the intake hole?
