Interference Versus Non-Interference Engines • Cars Simplified: Engine Design

The difference between interference engines and non-interference engines!
Interference engines have a lot of advantages over non-interference engines, but the latter is still produced. What are the differences? Can you still bend valves in a freewheeling motor? What can cause internal engine interference? Steve will answer that and more in this video!
It's good to know if your engine is interference or non-interference, but it's best to treat every engine like it's of the interference design when working on timing components!
Freevalve engines, while not discussed in the video, can still be an interference or non-interference design, the only difference is what is opening the valves.

I've recently gone down the combustion engine rabbit hole, and came across the term non-interference engine in relation to a timing belt repair. That led me to this video. Very well done...perfectly explained. My curiosity has been sated...for now. Now, back down the rabbit hole.

[@InuyashaMiles]

Wow. This was easy, quick and memorable info! I learned something!

[@ezeooo]

Bless your heart, straight to the point . I suscribed.

[@davemcguigan218]

You always give great, easy to understand explanations! You never disappoint!

I agree with , i saw punch of videos they just lab lab lab laaa

[@ZOK08]

Thank you for this video

[@Grant-vk6zo]

Excellent video 👍.

[@CarsSimplified]

Thanks!

[@briankeithnull194]

Thank, I'm in the process of purchaseing a 2015 Fiat 500 non-turbo. The car has 71k miles on it. It's due for the timing belt, tensioner and water pump to be replaced. I'm going to use this video as ammunition at the dealership to either have them do the service on the car or reduce the purchase price of the car. If they won't do either than it's time to walk away from the car and find a different one. Thanks for the video! Good job!

[@argniests5357]

HI there, thanks for the video. Do you know if a 1984 celica supre 5M-GE is a interference or non-interference engine?

[@he--ru362]

Thank you sir 🙇

[@zoly16]

Very nice explanations! Although i have a question, for example do you happen to know precisely if the N47 BMW engine is an interference engine or not? Because when I replaced the chains, I could rotate the crankshaft as long as I want, and it didn't feel to collide with anything (with the camshafts locked in place with the timing kit). Btw, the car works perfect since then, so no issues.

[@Real-Ruby-Red]

If the crank could rotate a full engine stroke with the cams locked then it's a non interference engine, if it wasn't your crank would stop when it hit the valves

[@thefonzeful]

nice. cheers

[@Fifou001]

i heard that you can also drop the compression of a cylinder by changing the lengh of the con rods to smaller ones, if u wanna turbocharge an non turbo engine and in the mean time fix an interference engine.

[@Lifesituations8000]

Is the 2AZFE with vvti an interference engine?

[@konquer247]

One way to convert an interference to a non-interference engine is to sandwich a cylinder head spacer between the engine and the head. The thickness of the spacer depends on the maximum depression of the valve. Of course you lose compression, but it'll be safe for more boost.

[@shimxininahi8024]

how do you release the interference when chain jumps on the 2arfe engines?

[@elizabethbryan8837]

What could cause chevelle deawoo trying to start but storing after timein belt burst

[@T_t418]

thx for the explanation but i still dont know what to call this type of engine in my language.

[@compilation8800]

Is Dodge Charger 2016 se v6 Intefrnce?

[@luckymutibo9848]

My belt broke on 1998 Toyota rav4, should I be worried of bent valves?

[@MidnightMarrow]

Non-interference engine, should be fine unless something else happened.

[@ghostyboy9469]

What about the non interference engines that are at the same height as a interference engine with the break away rods on the fiat or is that a hoax?

[@thetiagomatos]

Shit because of this i finally understood how an engine works.. thank you so much!!!!!!

[@user-xk5dr7gi7q]

The bezt video i see thanks

[@kellicees5568]

Smashy smashy! Poor valves!

Interference motors need to go the way of the Democratic party. COMPLETELY OUT OF EXISTENCE!
