On a 1994 Mazda MX-6 : Both the 2.0 liter four cylinder engine and the 2.5 liter V6 engine have a timing BELT
In a 1994 Ford F-150 : There were ( 3 ) engine choices : The 4.9 liter / 300 cubic inch inline six cylinder which has a gear on the crankshaft that meshes with a gear on the camshaft , so there is no timing belt or timing chain The 5.0 liter V8 / 302 cubic inch that has a timing chain The 5.8 liter V8 / 351 cubic inch that has a timing chain
An oil leak at the timing chain means that the seals are defective and must be replaced.
