mk3 supra smoke out of exhaust manifold
 

hello ive got a 1990 toyota supra turbo. its a 7mgte motor and its smoking white from the down pipe where it connects to the elbow of the turbo. theres no white smokes coming from the exhaust buts its doing this after i changed the head gasket. i put a new head gasket with arps head studs torqued them to 86 foot pounds and double checked them twice. the smoke onley happens when i drive it for 3 minutes but its nothing like its a lot just some steam. i thought it might be the head gasket but iam not loosing coolant. also i had the head machined and resurfaced. its just white thin steam. could this be the new gaskets forming in place until i drive the car. i put new gasket for the whole motor including the exhaust manifold gasket the turbo gasket and the down pipe gasket. could this be the gaskets forming in place becuase there new and have to burn to settle down.
