Engine Clicking And Tapping Noises problem #1

Exhaust header leak, audible ticking sound once warmed up in drive.

Gas Recirculation Valve (egr Valve) problem #2

Valley plate leak due to the fact that Toyota/Lexus utilized the improper sealant and used the improper amount, leading to the heat exchanger leaking coolant once the original, inadequate sealant begins to disentegrate. This could cause a condition where the engine could fail and someone could get hurt. Furthermore, all Isfs will eventually have a cracked rh manifold on the #8 runner. This can cause a fire hazard in addition to carbon monoxide poisoning.
