Parts for your 2016 Toyota Crown-Exhaust gasket

2016 Toyota Crown exhaust gasket — purpose, servicing and replacement

Based on Toyota technical sources — including the Toyota Electronic Parts Catalogue (EPC) for the S210 series (ARS210/AWS210/GWS214) and the Toyota Repair Manual/GSIC exhaust sections — the 2016 Toyota Crown uses multiple exhaust gaskets. These include the exhaust manifold-to-cylinder head gasket, turbo/manifold interfaces on 8AR‑FTS models, and ring or “donut” gaskets at pipe and muffler flanges. So yes, exhaust gaskets are fitted and relevant on this model year.

The exhaust gasket’s main job is to seal hot gases at joints in the Crown’s exhaust, keeping the system leak-free from the manifold right through to the tailpipe. A proper seal helps the oxygen sensors read cleanly, keeps the turbo spooling efficiently on 2.0T variants, protects nearby components from heat and fumes, and stops that harsh ticking or chuffing noise on cold start. On the 2016 Crown, you’ll commonly find a multi-layer steel (MLS) manifold gasket and crush-type ring gaskets at the front pipe, catalytic converter and rear muffler connections.

There isn’t a fixed time or kilometre interval for exhaust gasket replacement on the Crown. Toyota service literature treats them as “replace on removal” items: whenever a joint is separated, the old gasket should be binned and a new one installed. Outside of scheduled work, replace gaskets if there are signs of leakage, damage, or noise. Left to leak, you can cop exhaust odour in the cabin, skewed fuel trims, and poor turbo response on the 8AR‑FTS.

• Typical symptoms: ticking under load or at cold start, soot marks around a flange, exhaust smell, raspy note, or OBD faults from upstream sensor readings.
• Common causes: heat cycling, warped flanges, corroded spring bolts, or disturbed joints after other repairs.

When servicing, use quality gaskets (genuine or equivalent), clean mating faces, and follow the factory torque specs and tightening sequence. Avoid exhaust pastes or sealants upstream of the catalytic converter
