Toyota 1ZZ-FE 1.8L Engine Specs, Problems, Reliability. The 1ZZ-FE was a 1.8-liter inline four-cylinder gasoline engine out of Toyota’s ZZ engine household. Replacing the old 1.8 L 7A-FE engines, it was first presented in 1998, and in December 2007, its production already was stopped. This engine was used mostly for the front-wheel drive automobiles such as the Toyota Corolla or Toyota Celica GT, but also for the rear-wheel-drive Toyota MR2 Spyder and Lotus Elise.
Instead of a cast iron block used in Toyota’s 7A-FE, the 1ZZ engine has a die-cast aluminum cylinder block with thin (2.0 mm thick), chill-fitted cast iron cylinder liners. The engine block is geared up with a created crankshaft with 5 journals and eight balance weights, light-weight connecting rods, and aluminum pistons with full floating-type piston pins. On top of the block, there is a twin webcam aluminum cylinder head with 4 valves per cylinder (16 valves total). The 1ZZ cylinder head features laser-clad valve seats. The consumption valve diameter is 32.0 mm diameter and its valve lift is 9.3 mm. The exhaust valves have a 27.5 mm size and 8.4 mm lift.
The overhead intake and exhaust camshafts are chain driven. There is an 8 mm pitch roller chain which opts for an auto tensioner. From 2000, the engine was produced with Toyota’s Variable Valve Timing with intelligence’ (VVT-i). That system offered variable intake valve timing just. The consumption manifold was made from plastic and had long and straight consumption ports. The TRD version of the 1ZZ-FE engine had its own cast aluminum intake manifold. The 1ZZ-FE engine got sequential electronic fuel injection (EFI) with twelve-hole injector nozzles and a distributorless, coil-on-plug ignition system (Toyota Direct Ignition). The exhaust side has a stainless steel exhaust manifold and three-way catalytic converters.
The 1ZZ engine did not make big regard among purchasers, and in 2007, Toyota changed it by the brand-new, for that duration, 1.8-liter 2ZR-FE engine.

Toyota 1ZZ-FE 1.8L Engine Problems and Reliability
The common problem for the 1ZZ engines, produced before 2005, is high oil intake. The reason was in the bad design of oil piston rings, which was revised and improved in 2005. Cast iron liners are thin and non-rebuildable. Similar to laser-clad valve seats, this is not something that can be repaired in a conventional factory. The 1ZZ-FE engine is known as a one-time item. The engine features a long stroke (91.5 mm) in a relatively small displacement. This mix produces large vibration loads. This mix in the 1ZZ engine creates big vibration loads, which the rear engine mount isn’t able to manage too long.
An approximate mileage which you can leave a 1.8 L 1ZZ-FE is 125,000 miles (200,000 km).
