The timing belt is what keeps the whole engine running smoothly, it ensured that the valves to not hit the pistons... If the belt is not replaced as stated by the manufacturer there is a high chance of it snapping, causing the valves to hit the pistons and the engine will then stop!

It is one of the most important parts of the engine. A lot of older engines, and most new Mercedes-Benz engines use timing chains, these are the same in principal, however they last a lot longer and start to rattle when they are near to breaking, they can easily double the distance of a timing belt, however they are more expensive to use.

There is a simplex timing chain and a duplex timing chain, the simplex is a single chain, and the duplex is a double chain, which will obviously last longer.

What is the function of the timing belt? what happens when the timing belt is not replaced according to the manufacturers standard?

Hi guys, im a new member & this is my 1st post. just got a prob, direct ignition system has better fuel consumption, lower max speed. indirect is the opposite. Does anyone know what the price difference would be? i Assume that the D.I system is expensive than the IDI. However if the price is so high, it may be wiser to buy the cheaper IDI system vehicle even though it has a poor fuel consumption... Just wanna have a rough IDea about the cost difference..then i can get an idea of how many liters (or how long) it would need to compensate thanks guys..

Hi Bree,
What is it specifically you want to know, is there any area you want to know more about than others?
Is it just car makes and models you want to learn or do you want to learn how they work?

Also, are you interested in Modifications?

hi clarky here, can any body help me with my cam timing on my micra which i belivehas not been set up correctly.<br />The engine runs ok but seems to be holding back when driven normaly also every now and then it pops out of the exhaust.<br />Also it runs very lumpy on tick over, but revs ok.<br />Upon looking at the cam timing through inspection cover it looks like it has had the timing chains replaced with a rectro fit kit as the chains only have one different colured link on them therefore i canot tell where the cams should be (the sprokets have dots on them)so can any one help with the positioning of them. many thanks <br />clarky.

Hi, First thing I would have to ask is, what year is the micra and what year is the primera you plan on taking the donor plant from?
You are also aware that you may have to strengthen the body, upgrade the brakes and suspension to do this aren't you?

I can understand why some people enjoy spending thousands on projects like this as at the end they have a one of a kind car, which is a wolf in sheeps clothing. Which is ok, but the insurance will hit you big time for modification.

I am not trying to put you off and will help all I can, but I have to let you know the facts before you get your hopes up. If you still want to do it, then go ahead and tell me what year the micra and primera are?

Thanks

Nick
