...post. Back in the 70's I had several Datsun rigs, pickups and a 510 sedan that had a great little 1600 OHC engine. That engine had a timing chain with a nylon tensioner/guide that was spring-loaded. The sprocket that the chain drove the camshaft with had three marks on it for adjusting the...

It can be boiled down very simply: each part is assessed for it's ability to either cause catastrophic failure directly, or by being the head of a chain (cascade failure) of failures. A number is assigned for risk assessment severity. Then, occurance is predicted from past historical review...

The high stresses placed on timing chains by direct injection is increasing service intervals. Most direct injection systems require additional fuel pumps capable of producing very high pressures in order for the injectors to 'work' (I say 'work' to keep it simple). These pumps are often...

I would have to pay for a timing belt change, so I like the chain. In my small world I saw a chain fail once. A classmate in collage had a really high milage raged mustang and turned if off once and it would not start again-chain broke.

I must've missed something Wheaters? Who's putting the timing chain at the back of the motor? I've only seen one piece crankshaft with gears on small engines, like lawn mowers?

Putting the timing chain at the back of a longitudinal engine/transmission setup isn't a sound idea, imho, because you can't easily get at it without removing the engine. Nor is making the drive sprocket for the chain an integral part of the crankshaft. When the plastic (nylon?) chain guides...

There's good and bad motors when it comes to timing chains. The GM 2.2 from the 1990s for example. They used a timing chain and tensioner to keep it "right", due to the length between the cam and crank. (Push rod engine, durable but design flaws for the timing chain). The tensioners had a...

I prefer timing chains. yes they're a bit noisier, but they last a lot longer under normal use, as well as keeping the specific timing of the cam and crankshaft in sync. Having said that, timing belts have come a long way as far as durability and dependability. Kevlar is the biggest leap in...

...are noisy. Belts are quieter but need to be replaced at 100,000 or so. For me replacing a timing belt is no big deal. If I had to pay someone to do THAT would be a big deal. My old Caddy has 4 camshafts, 3 timing chains and 245,000 miles and appears to be all original so the chains really do...

I did. Didn't see a Timing Belts 1% better reference on anything reliable. You seem to get your feelings hurt whenever someone questions you. This forum purpose is the exchange of information. If your reaction is caustic every time you are challenged, you are going to be a very angry person.

Son do you have anything better to do than follow me around sharp shooting every thing I say? Its not that hard to understand. Weight on a rotating mass... Wich one is lighter? #1Google this timing chain or belt efficiency #2Read #3 learn

A timing belt increases mpg about 1mpg. From what I have read. a chain lasts longer. The combustion chamber shape is pretty trick in this little motor. At high compression knock managment is a good thing is proven and works well. ...add a turbo or any power adder later its a must. Detonation...

Amen Reverend E-P A, amen.

Fixed that for ya. :) First answers I can think of are sputtered cylinder linings, cam cover with integrated bearing bosses, single overhead cam, and timing chain instead of a belt.

...will be assembled, and start the process again. It is going to take some time. Because EM cares enough to design this engine with a timing chain (higher cost) instead of a belt (for long term durability), I am confident that they will not "rush" a sub-standard engine to production. If...

Just a comment on the engine durability issue. They are going with a timing chain instead of a belt, for durability. Engine timing belts last 100k miles. They must be planning on getting a lot more than 100k out of the motors? Or they don't want people to have to go thru the hassle of worrying...

Thanks for sharing those, Tao. The first time I tried to look at them I couldn't get them to play but I had no problem today. :-) Z

Unfortunately, for whatever reason I can't get any of the videos to open on my iPad.

Yes, also he mentioned: * a full belly pan on the underside to facilitate better aerodynamics - I know there has been some discussion on the forum regarding if EM was considering this. * discussion of the variable valve lift technology should put some of those questions to rest *EGR GREAT...
