Is a 22re an interference engine?
Interference engines are 4-stroke internal combustion engines. Toyota 20R, 22R, 22RE, 22RET, 2RZ-RE, 3RZ-FE engines are all chain driven interference engines.
What happens if you have a broken timing chain?
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. The valves, pistons, and other vital components of the engine will not be damaged. But still, you don’t want to take the chance of being stranded somewhere because of this.
What is the function of the timing chain?
The timing chain is a critical component of the internal combustion engine. Its function is to keep the camshaft and crankshaft rotating together at the same speed. This enables the valves of the engine to open and close at precisely the right times. Looking for a good online repair manual?
Can a timing belt break in an interference engine?
In some cases, an engine might be severely damaged as a result. That said, we have seen “lucky” cases where there was no valve damage after the timing belt broke in an interference engine. If a timing belt or chain breaks in an interference engine, the first step is to assess the damage.
What does it mean when your timing chain rattles?
Chains that have slipped time have slackened and can sometimes rattle during cold start or idle, or produce a swishing or scraping noise. Loose chains typically hit the inside of the timing chain cover. A rough running engine may accompany such noises. Test-drive the vehicle and while slowly accelerating listen for any backfiring (popping) noises.
How old is the timing chain on a Toyota 22R?
Every Toyota 22R series engine with the single row timing chain and plastic timing guides (1983~ish – 1995) that I have ever purchased with over 100,000 miles on the engine has had a driver’s side guide that was either partially broken or just totally gone.
What should I do if my timing chain broke?
If the pistons are not damaged, then the least expensive route for repair, would be to replace the entire cylinder head with a rebuilt one as it is less labor intensive than rebuilding your existing cylinder head. If the pistons are damaged, then a complete remanufactured or used engine would be the least expensive route to repair the vehicle.
What happens when the timing belt breaks on a car?
Interference refers to the fact the intake and/or exhaust valves occupy the same space as the pistons. The timing belt/chain keeps that from happening at the same time. If the timing belt or chain brakes, the valves and pistons will hit each other. Valves can bend and/or break and the pistons can be damaged.
How much does a broken timing guide cost?
It makes a great bargaining chip when you can show the seller that the timing guide is broken and then inform them that it’s an $800+ repair at a shop. If you can fix it on your own it will only run you about $100 in parts and a Saturday’s worth of time. Loading…
