How many miles on the 93, they are susceptable to valve guide wear which emmits a loud woof woof into the intake if it's an intake valve and the woof goes out the exhaust if it is an exhaust valve. White smoke and chuging could be caused by a burnt or stuck valve too a sign of incomplete combustion. Should do a compression test.....
