Toyota swapped the dual-row timing chain used in older engines for a single-row chain with plastic guides in 1983. The new system reduced drag on the engine but introduced a new maintenance problem. After about 100,000 miles (160,000 km) of operation, the chain may stretch to the point that the hydraulic-operated chain tensioner cannot take up ...
Metal timing chains have become more widespread in car engines produced since the 1990s, due to the lack of the regular maintenance task of replacing a rubber timing belt. While the chains themselves are subject to minimal wear, lubrication of the chain or failure of the tensioner and chain guides can cause maintenance issues.
Other manufacturers may modify the engine after it has left the Toyota factory but the engine still keeps the original Toyota designation. For example, Lotus added a supercharger to the 2ZZ-GE in some versions of the Lotus Elise and Exige, but the engine is still labelled 2ZZ-GE, not 2ZZ-GZE. Examples: 3S-GTE 3S – Third model in the S engine ...
This new engine uses a timing chain instead of a timing belt. It also incorporated laser etched valve guides directly in the block, rather than the old shrink-to-fit valve guides in the preceding Corolla motors (4A-FE & 7A-FE). This prevents oil burning and valve guide failure in the future.
The Toyota GR engine family is a gasoline, open-deck, piston V6 engine series. The GR series has a 60° die-cast aluminium block and aluminium DOHC cylinder heads.This engine series also features 4 valves per cylinder, forged steel connecting rods and crankshaft, one-piece cast camshafts, a timing chain, [1] and a cast aluminium lower intake manifold.
The timing chain rode on one pivoting chain guide resting on the ratchet tensioner and one fixed guide attached to the engine block and cylinder head. The 1991 to 1998 DOHC engine had an upper timing chain guide in between the camshaft sprockets. The timing chain was lubricated via cast-off from the top of the cylinder head and one 'squirter ...
