[@josephherron7671]

I have NEVER heard of valve to valve interference until this video. It makes sense now but I think in this specific case you're correct. There is just no way they hit each other unless the lash is WAY out of spec. So far out that the valve can't completely close; or put another way, NO LASH AT ALL. Which would cause problems way before the belt breaks.

As the original owner of a 1989 Dodge Spirit ES turbo car AND the factory issued shop manual for the car, I can tell you from my own wrenching experience over all these years, a corporation can and sometimes does make mistakes in their printed literature about their own product. It's not often, but it does happen. BTW, the 2.5L SOHC engine in the Spirit is virtually all original except for 5 head gaskets, one timing belt, and a valve grind. Over 300K miles now. Love your channel David. Hope you keep it going for many more years.

I would never own a interfering engine especially after learning all the different ways this event can happen. Thanks for Educating the Serious DIY's...👍👍

probably the clearest and most technically superb video Ive seen on this issue.

[@agustineable]

Nice work, I agree that if you have a problem with something that you should check it out for yourself and see what the problem is and why it is happening, and seeing it with your own eyes is priceless as far as solving the issue. I also like how you did not have a problem with admitting you may or may not have been correct and explained it, too many people would just sweep it under the rug or blame somebody or something else and hope nobody says anything, and move onto something else. Subbed

I can admit that I am not perfect for sure and there is always room for learning and for improvement on my end. I certainly havent seen it all and each day I come across at least one thing I was wrong about or that I didnt know. Thanks again for watching!

[@75spitty]

Wonderful job! I love this. I keep promoting your video on the facebook PT forums. Too many people want to drive it until it breaks because it is "non-interference". They're so wrong.

[@jamesworsham2312]

It don't matter if it's interference or non-interference. When you're getting down the road at 60 70 80 mph and the belt or the chain comes loose something is bound to smack they're not like the old engines back in the day. These engines have no tolerance for mistake hopefully you will not learn that the hard way on your own vehicle

[@rey3468]

This is an outstanding video, and part of an outstanding series, that resolved a long standing question about the 2.4 liter twin cam. You did a great job of forensic engineering, that never would have been needed if those diploma engineers had properly insisted on exhaust valve reliefs at the tops of the piston crowns. That would have only reduced the compression about one, or at most two, percent and saved a lot of trouble for a lot of people. Thanks again.

[@davidtigert4842]

MAny companies are installing 4 valves for each cylinder. You only need 2 valves per cylinder. 1 intake @ 1 exhaust. You are asking for trouble with 4.

[@davidtigert4842]

1 Cam @ 2 valves per cylinder. The old slant six cylinder would go a long way.

Really nice to watch a video by someone who knows their stuff vs some of these videos out there where they just want to show off all their snap on tools. I admire the detail you put in you work. Question: Are you mostly self taught and always just loved working on cars or did you go through a lot of training to get where you are ? Again, great videos David !

Thanks for understanding my process. I have been at the same dealer for going on 21 years now.....I like to think I am mechanically inclined and like most of you....just need the info for me to do the repair. Much like fixing the washer or dryer at the house or the a/c unit or even the plasma TV. If I have the info....I can take the task on. Its all bout finding the knowledge from somewhere. I have worked on cars one way or another since I was 16 so its pretty much my life I guess.....I wouldnt say that I love it, its more of a saving money and fixing it myself thing.

[@andrewhallett-patterson9778]

Great information and descriptive learning Dave. Valve to valve contact was a prominent issue in early multi valve overhead cam diesel engines with primate electronic injection, where the early belts or chains failed, especially in Australia where extreme heat, multi trailer combos are prominent. In all engines failures I've diagnosed with this description, the valves had not touched the pistons, due to the volumetic concaved pistons (increased volumetric area), but had edge contact with the opposing bank, resulting in major valve head degregation, from chips to complete severance. Other diagnosis of terminal failure include exhaust valve failure due to Jake Brake failing to release after disengagement, Hobbs switched fans causing belts/chains to jump a notch when engaging due to failure of soft start mechanism affecting cam timing, early ECU failures, most notably on Euro trucks with primitive VVT, losing sensor activity, suddenly engaging limp home without warning, and regarding the timing without confirmation of either cam / valve positioning. Add the failure of belts due to atmosphere and mechanical exposure, and overstressed timing chains, and you have very expensive repairs as the engines were usually destroyed by shrapnel from valves and / or disintegrating turbo turbines. Oh....one funny issue seemingly encountered on industrial Detroit diesels was the engines would fall out of timing without warning for no obvious reason but never damaged valves. When the heads were removed exposing the combustion chamber, the valves, usually inlet, had caught the edge of the exhaust valve, rendering retraction impossible. 👍👍

Thanks man.....appreciate the comment and for you watching!

[@snaproll94e]

Thanks. Those dents in the piston almost look like they fit the bottom side (radius) of the exhaust valve head, more perfectly than the top side like you demonstrated. As you showed, the leak down test told the story. When you found the factory cam alignment holes were off, I personally would have been tempted to loosen the exhaust cam sprocket bolt, align the cams using the factory alignment holes, retorque the exhaust sprocket bolt do the leak down test and then see if the engine would then start/run. Regardless, once you found the exhaust valves were leaking, you knew you were going to have to pull the head to fix all that was wrong (and do some preventative repairs while you were in there). You are obviously a very good technician and teacher, thanks for making the videos!!! It's an Excellent series, I've shared them with my son and brother that own PT's.

Great explanation Dave. Like you, Chrysler made it more difficult to understand and we all learned something about valve to valve vs valve to piston clearance.

[@MotorCityMechanic]

Thanks Wyatt! I learn something everyday so I learn with all of you watching.

[@briansaunders5557]

Thanks

[@Keirnoth]

Stumbled upon this video because I wanted to know about interference engines (I'm still not sure if my 2004 Toyota Camry V6 is interference or non-interference, I keep getting conflicting info) and you helped explain to me what that concept means. You made it easy to understand even from a non-gearhead's point of view. This also goes to show why Chrysler gets its reputation as it does - it just seems like "good engineering" wasn't a term in design. They make slick looking cars but they always have these strange faults. A non-interference engine but the valves can still smash into each other, but they're wrong about it? Might as well just should've just added "Yeah, we're stupid" at the end of that service manual blurb.

[@donnyhitz]

I really find it astounding that Chrysler's service bulletin was wrong on this issue. That's a fundamentally gross error. You're not wrong to believe mostly all of the service bulletins, notices, etc. that are released by the major auto manufacturers. Errors are rare, yet they do happen. Step by step analysis is still your best tool. I enjoy your videos and your teaching style. Thorough without boring this old shade tree mechanic. Keep up the good work.

[@MotorCityMechanic]

Many thanks Don! Appreciate the comment and for your time spent watching

[@djr3485]

Errors are unfortunately rather common in automotive service publications because they are written by engineers who rely too much on theoretical and inflexible modes of knowledge. In reality, common sense and experience are often far better guides when dealing with mechanical realities than a whole lot of gobbledegook aimed at addressing endless possibilities.

[@CarsSimplified]

Was the valve spring for the affected valve weak or damaged? I can see one letting the cam fling the valve further than intended, the intake valve catching it, and pushing it down into the piston. Having that happen to two parallel exhaust valves at the same time would be incredibly unlikely, though.

[@leo28a]

Great stuff.. David thank you You definitely have nailed it But my question which type is a majority..? What's the percentage of interference & non-interference? And which one is main stream production today and in the past. ?

[@kmath50]

Great video! As an owner of two Chrysler vehicles with the 2.4, this is very useful info. I changed the belt on both mine at the suggested interval, and now I can see that I am glad I did. The exhaust valves did come into contact with the piston. Did you have to replace the piston in this case? Is this discussed in a later video?

[@MotorCityMechanic]

Piston was okay and I didnt seen the need. No issues with it running lol. If the belt breaks your okay....its just when someone times it up wrong or does something like in my case with the cam shaft alignment pin. Thanks for watching Kirk and for the comments.

[@user-ol5rj8qn9o]

Lost belts on older Camrys (2) different cars. One lost a belt due to catastrophic failure of the idler pulley (due to over tension by a quack mechanic who I had replace the old belt). The other lost the belt due to the shaft breaking off the water pump. Both cars were saved due to the non-interference engines. ALL engines should be built like that.

[@norcal8718]

Awesome video brotha 👍🏻 I'm surprised in all your years of wrenching you've never heard about valve to valve contact possiblitys, we learn something new everyday right. But anyway my question is have you thought about notifying Chrysler of your findings of this situation? I wouldn't be surprised if they wanted to hire you on as an engine designer (for real) you definitely know your shit. I've been a mechanic at a Chrysler/Plymouth/Jeep dealership for 13 years so I can tell you got skills 🔧

The service info is assuming the belt is on timing, if it jumps of course it can hit the piston, especially that engine where the piston is above the top of the block.
