when im driving my 98 turbo wagon at higher speeds with WOT i get a pop, pop wuzzesh, wuzzesh from under the hood ,and an aroma of , did you ever boil turpentine and radiator caps like odor from the dash vents, what the hell is this
What is WOT? And I love your description of the noise! No I have never boiled turpentine, but if you detect an odor like radiator coolant from the dash vents, you may have a leaky heater core. What you describe, the pop, did it only happen one time or every time you drive at high speeds, also your definition of 'higher speeds' may be different from mine. 70? 100? A hose bursting will make a sound like that, or the radiator cap releasing excess pressure in to the recovery tank.
WOT is wide open throttle. The popping noise is the blow off valve that regulates the output of the turbocharger. The smell is stuff burning off the exhaust. It usually doesn't get that hot.
thank you guys, I did some checking and turbo pop off @ 7 lbs ,did some adjusting now increased pop off @ about 9 pounds really adds to performance and the pop pop is for engine overstress i been told , dosn,t do it but rarely, speeds maintaned is seldom over 85 to 90 avg. hwy. 50 jim
