Just bought a 89 Supra Morning startups would involve 1st turn over would produce an instant start up to slowly idle down with white smoke rolling out of pipe only to shut off. After a numerous similar tries I finally have to pump accelerator to finally get it started. After starting I have to keep revved (1500) until warm up kicks in.Fills my garage up with white smoke After warn up the smoke diminishes to small amount of smoke . Anyone with any ideas?

White smoke almost always means Blown Head Gasket.

Your mom blew my head gasket.
