What would happen if a timing chain broke?
A broken timing chain will cause an engine to not start or fail while driving. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves. The valves themselves will bend and potentially ruin the engine.
Will engine turn over if timing chain broke?
No matter which type of engine you have, a broken timing chain will cause your engine to immediately stop running and turn off. If you have a non-interference engine, the result of a broken timing chain will not be as severe. It will simply cause your engine to turn off but that’s all.
What are the symptoms of a timing chain breaking?
Signs of a Faulty Timing Chain
- Rattling Sound on Starting the Engine or Idling. A common finding in a vehicle with a bad timing chain is unusual rattling noise when the engine is started or when brakes are engaged.
- Misfiring Engine.
- Contaminated Engine Oil.
- Check Engine Light.
- Inability to Start the Engine.
What is the difference between an interference and non interference engine?
An interference engine is a type of 4-stroke internal combustion piston engine in which one or more valves in the fully open position extends into any area through which the piston may travel. By contrast, in a non-interference engine, the piston does not travel into any area into which the valves open.
How much does it cost to replace timing chain?
Typical costs: Hiring a mechanic to replace a timing chain typically costs $300-$1,000, depending on the make and model of the vehicle, its age and whether the work is performed at a dealership or an independent shop. Purchased separately, a timing chain typically costs $50-$250 or more.
Can a timing chain break?

How to set timing on 22R engine?
bigrocks2 said: A quick tip to help you set timing on the 22re if you suspect the tps is faulty. Disconnect the tps plug and jumper the two bottom terminals together. this tells the computer that it is really at idle (no throttle angle) you also need to jumper the connector at the fender also.
Are 22R and 22RE blocks the same?
for the most part the 22r and 22re are the same block and head. the one difference is that the re has a single row timing chain and the r has a much better double row chain. the intake and exhaust manifolds are inter changeable but if you use the 22r block your going to need the 22r head as well. if you want some more power, pick up a 20r head and put it on your 22r block and use the efi manifold. the 20r head has slightly higher compression and the intake track is a strait shot. toyota
