Are Kia Engines zero tolerance (2002 Spectra)

.40-.45 should be fine.

All the KIa engine that I have listed are interference fit engines
best is to treat all engines as interference fit as that way you will not go astray
when the head is off turn up side down and fill the combustion chambers with water (Valves closed) and if the water runs into the head openings then the valves are bent
always place the no 1 piston on tdc before removing the head or replacing the head
leave the rockers loose so that the cam shaft can be turned with out the valves opening till you get the timing marks to line up

Hi.

It depends on the model. Kia Spectra comes with engines that ranges from the 1.5, to the1.6, 1.8 and 2.0 liter models. Most engines have the spark plugs located on top of the engine block under a plastic cover. Under the plastic cover you may find the plugs or two coil packs. In the last case the plugs are located under the coil packs.

White smoke is water. Blue smoke is oil. Black smoke is excessive fuel.
