Toyota 1AR-FE 2.7L Engine Specs, Problems, Reliability. The 2.7-liter engine of the AR family was launched in late 2008 in the Venza and Highlander. The engine was built using the parts and components of the smaller 2.5-liter 2AR-FE engine.
The engine has the aluminum cylinder block taller than the 2AR. The cylinder block height was increased for the new crankshaft with 105 mm stroke. In this manner they accomplished the increasing of engine displacement from 2.5 to 2.7 liter. There is the same aluminum DOHC 16-valve cylinder head with hydraulic lifters. Both camshafts are equipped with variable valve timing system called Dual-VVTi.
The single-row timing chain drives camshafts. The engine includes the variable geometry intake manifold ACIS. There are lots of functions likewise similar to the 2AR engine (you can check out them in the 2AR-FE review). The main distinction is the output of the 2.7 liters, mainly in the torque numbers which is more actual for heavier cars like the Highlander or Venza.

Toyota 1AR-FE 2.7L Engine Problems and Reliability
The engine turned very good. We didn’t discover any noticeable problems or problems. The engine is included by a knocking sound from the VVTi system when it is cold, but this does not impact reliability and durability. Cylinder block durability limits the engine life, and it is about 150-200k miles.
