Hey

So I did take my car out of storage gave it an oil change, new battery, and filled up the tank with premium gas/fuel system cleaner.

Took it out on the freeway for a spin, had it in high RPM's around 4-5000 and noticed white smoke pouring out of my tailpipes. Could this be from the condensation of having it sit in storage for 4 months?

So then I parked my SC400 in my car, and I revved the engine and here is what happens... I feel a very slight vibration with the engine shaking pretty badily. When I take off, especially from 0-30 mph. When I'm on the freeway it is fine expect for white smoke pouring out the exhaust. It only happened when I rpmed it high, my buddy told me to do this to burn the old fuel out of the car.

Could I seriously have a bad headgasket cause that would really blow.

 

one good way to see about a BHG is to test the coolant for hydrocarbons. You can get a tester at any autoparts place or take it somewhere. I owned a MKIII with a 7m and white smoke and bubbles in the coolant always meant the dreaded BHG heh.
