Not sure if this is the correct place to post or not. I've had a white smoke and power loss problem for a few months now. Randomly happens but when the smoke starts the power goes to crap for a bout 20 seconds and returns to normal. 2 days ago I decided to add a high flow intake elbow to go along with my ******s and when I took it off i had some milky oil drip out of the boot. I have been missing some coolant about a inch or so in the reservoir. Oil was a little low maybe 1 or 2 quarts after a 5k oil change. Is it time for Head gasket replacement? Truck is a 2008 with 205k miles. ******d and tuned
