can an intake manifold gasket leaking cause the engine to take longer than normal to heat up? what would it cost to replace the gasket if that's the problem?
heat takes a long time to get hot on 1996 Buick Skylark
sounds like a thermostat problem.the intake gasket will run 400.00 to 600.00 bucks
Are you sure it is the manifold gasket mine was the down pipe on the back side was cracked. You most likely have a open therma stat. Replace it with a 185.
