Does a Toyota 4runner have an interference engine?
All 2019 Toyota 4Runners have timing chains and are interference engines.
What are non-interference engines?
Put simply, in a non-interference engine, when the piston is at top dead center (TDC), it will never go higher than a fully open valve; that is, the piston can never “interfere” with the valves. Conversely, in an interference engine, the piston could occupy the same space as an open valve.
Is the Ford 1.5 Ecoboost an interference engine?

Does the 1.5 EcoBoost have a timing belt?
The 1.5l engine borrowed an innovative camshaft drive system from the 1.0 I-3 cylinder engine. There is a timing belt, but this belt operates in engine oil that reduces noise and increases durability. EcoBoost engines are very efficient due to the combination of turbocharger and direct fuel injection.
What kind of engine is a non-interference engine?
Non – Interference engines are the type that have significant clearance between the valves and pistons. Below is a list (but not all vehicles) of interference and non-interference engines: •1.6L DOHC (4A-F & 4A-FE) non-interference (Corrolla, Carina II, etc ) • 2.8L V6 90 100 Quattro A4 A6 Interference. .

When to change the timing chain on a non interference engine?
