I was going to try to go find the information for you but I just noticed goofyone is the current moderator and he is great at answering these kind of technical questions. I believe the subject was covered in a Tech Talk if these cylinders are the same ones that will be Flame Sprayed. :-) Z

The use of a timing chain on the Elio engine translates to a low-maintenance long-running engine. Timing chains typically last the life of the engine without requiring servicing. There are scads of cars with hundreds of thousands of miles on them still running on the original timing chains...

Dude!!!!!!! What a fun vacation. Why don't you just rub it in. I found a tape many years ago of my wife and I back in the 70s enjoying yachting week in what is now Croatia. The other girl was Marys girl friend I don't remember the other guy. be sure you have sound.

...isn't next on the page. Otherwise it's just a waste of bandwidth and I prefer to be economical, just like the Elio.:D I agree about the timing chain which hopefully negates any chance of valve to piston arguments. I've owned both types of engine and never had trouble in that respect from...

Ironically the importance of interference from either piston or valve is rendered rather moot with the addition of a good timing chain (just my opinion). I rather thought our little foray here more revealing and interesting. Except that you still fail to use the reply button for clarity of...

...the great info and feel free to share anything else you can as we would love to know more about this engine. :cool: I know one big question many of us have is will this be an interference engine? I know with the timing chain this should not be much of an issue however it would be nice to...

At this time I do not have any information abut this being an interference engine however it would not surprise me if it is. What I can do is help clear up some confusion about variable valve timing. The fact of the matter is that this engine will have two-step variable LIFT and not variable...

Some ztec engines are non interference, others are interference, depends on which cams and pistons are installed from the factory. While a US spec 2.0l focus engine is non interference, some of the race chassis I tinker with that are "powered by ztec" are interference due to higher lift cams and...

My ford zetec engine is non-interference and it has variable exhaust valve timing. I specifically sought a non-interference engine since my previous car (plymouth with an interference engine) died a premature death due to a timing belt failure with only 40k miles on the belt. I didn't do an...

Good question. Most high compression engines tend to be but since the Elio will have a timing chain, it shouldn't matter for 100,000 or many more miles. Typically, chains just get too loose and loud and the timing will start to suck. It'll be obvious that it needs changed before it goes. I'd...

Yes, due to the adjustable valve timing it is almost certainly an interference engine. Though the chain should alleviate any concerns in this area.

Has it been mentioned anywhere if this will be an interference engine design? At least with a timing chain you don't have to worry as much compared to a timing belt if it is an interference engine.

Hmmm...I'm no expert on variable cam phasing, but after watching the CAD video a couple of times, I can't see how the timing will vary with the cam gear 'hard mounted' to the cam shaft...unless, of course, the cam is hollow (would have to be with cam phasing anyway) and the actuator is that...

Timing belts still have their place they just aren't as suitable for low maintenance cost and reliability in the long term. On a light weight high revving engine the low mass is certainly appreciated.

Chain drives tend to make a noisy protest for some time when they aren't happy and last a very long time provided the engine oil is changed on time. Belt drives are cheaper but need changing every so often and this can mean higher maintenance costs. They stay relatively quiet when about to fail...

Here's a link to a YouTube animation of the motor posted almost a year ago which clearly shows a SOHC... BTW... My 5.0 liter R Spec motor in my 2013 Genesis is a DOHC motor that utilizes chains not belts... Belts are inexpensive compared to chains, but the higher performance engines will...

...production process we are looking at high pressure die cast. Can you answer why you have placed a support bridge on the head for the timing chain housing? It would seem that this support is going to hinder the installation of the timing chain not only for initial manufacture but also for...

Yes, obviously. I was just wondering where the pushrod comment came from (seems it was left field) as all the drawings clearly show a chain driven SOHC design. ;) In fact I don't know if ANY manufacturer has ever produced an inline 4 cylinder engine in the last 40 years with pushrods--that...

It's pretty easy guys, they just put a timing chain in the place you'd put a timing belt. Doesn't mean there are pushrods, been an OHC engine from the beginning :)

I think you're probably right. I must have been remembering an older post I read somewhere. There was a mention of using a timing chain instead of a belt on the new design. Belts would only be used on overhead cams. Then again they do say they're using a chain instead, which COULD be a...
