hey guys im new hear just looking for answers on why my 92 4x4 v6 4runner is missing at idle and when i drive the motor sounds like injectors idk what it is can someone help me out

note: when start up in the mourning or anytime engine cold it has white smoke out of the tail pipe could it be my head gasket going? also no water in the oil or no need to fill radiator can someone help me out where to start looking

things done cap, rotor ,wires and plugs has all been changed

Checked your sparkplugs?

kamahaobuilt13

changed all the plugs and wires

but would the plugs cause a miss idle and injector sound when driving??

What do you mean by "injector sound"?

abecedarian

injector sound? you mean a 'tick'?

kamahaobuilt13

yes ticking sound noticed oil on the block near the 6 cylinder i gotta do a compression test then from there ill see whats up i think maybe head gasket going?

abecedarian

oil on the block is most likely a leaking valve cover seal.

and a ticking sound could be an exhaust leak or loose valve adjustment

LOL! Yes thats normal. These engines have the "Positive Crankcase Ventilation" system, or PCV. It uses vacuum to draw crankcase gases back into the intake to be reused. Thats typically why you get gunk build up in the intake area. By taking off the oil cap or taking out the dipstick, you cause a vacuum leak.
