It sort of is. I'm fairly certain engines manufactured by BMW, Mercedes & Porsche have always used timing chains no matter the fuel type. That being said, no guarantee they use their own engines in their own cars. With Mercedes, the A/B/CLA/Citan vehicles from about 2015 onwards have used Renault engines. Andy.

RMweb Premium MJI Posted December 14, 2020 RMweb Premium Share Posted December 14, 2020 Chains are not neccessary better, some of the BMW V8s have huge long tensioner strips between the banks and tend to stretch. My previous car had a cam belt equipped V6 and that was quite easy to change. Looped around 2 cams, an adjustable idler, another pair of cams, a tensioner. So inline chain is proabbly better, V belts probably better Link to post Share on other sites More sharing options...
Kickstart Posted December 15, 2020 Share Posted December 15, 2020 I have no objection to belts, if they are reasonable to change. The twin turbo Maserati V6 has the silly idea if the cam belt driving the water pump, hence if the pump seizes it will wreck the belt to maximise damage. Belts have the advantage that they don’t stretch, hence the cam timing stays consistent over the life of the belt. Chains wear at the pins, get longer and throw out the cam timing. But a well specced chain should last. My MX5 has a cam chain (Ford based engine), which is convenient All the best Katy 1 Link to post Share on other sites More sharing options...
RMweb Gold Dunsignalling Posted December 15, 2020 RMweb Gold Share Posted December 15, 2020 The cambelt/water pump relationship is pretty widespread. Where applicable there's a new pump included in the kit. Even where one isn't, water pumps only cost about thirty quid but nowadays often take the same amount of dismantling to fit as the cambelt itself. Common sense to replace it while its get-at-able.

Kickstart Posted December 15, 2020 Share Posted December 15, 2020 I wish they were that cheap (the Maserati one used to be a reasonable price, although not cheap, they are now £300 for a pattern one and £1200 for an oe one - a lot of money every 2 years) and it renders a readily available generic service part to now need a vehicle specific part. All this while making a failed water pump result in almost instantaneous engine failure. The only reason for this seems to be packaging on modern cars, and it would be even easier to package an electric water pump (which also saves pumping coolant around when not required) All the best Katy 1 Link to post Share on other sites More sharing options...
RMweb Gold Dunsignalling Posted December 15, 2020 RMweb Gold Share Posted December 15, 2020 Continuous pumping of water isn't wholly about cooling, it also helps equalise temperatures throughout the block and head as the engine warms up. Coolant circulates, albeit at a reduced rate, even before the thermostat opens. John Link to post Share on other sites More sharing options...

Ford also use it and call it a Duratec. (Assuming an MX5 NC).

Kickstart Posted December 15, 2020 Share Posted December 15, 2020 Which can be done by varying the speed of an electric pump. Could even initially reverse the direction of flow to warm the block more quickly from the excess heat from the head. Even with a mechanical pump, they can easily be driven by the accessory belt without risking instant catastrophic engine damage when the pump fails, even if the pump is behind the cam belt.

Diesel-engined Fords used Peugeot engines for many years, and may still for all I know, though possibly made under licence rather than bought-in. A friend has a Focus on a 65 plate that has basically the same 1560cc Hdi motor my 2010 Pug 207 had, albeit in a much beefier state of tune (130 bhp against 92, I think). AIUI Peugeot developed that engine jointly with BMW so it probably cropped up elsewhere too. Mini? 1-Series? All very incestuous.....

Which was when Ford had the Premier Automotive Group, why design three different floorpans/engines/gearboxes etc etc when one will do? I had a good job a few times when I had to go to Hiroshima and photograph the production line and factory areas for records, I took three massive cases only one had clothes in, I came back with two of them packed solid with Kato N gauge models/track.....the exchange rate was excellent back then, the models costing about a quarter of what they did in England at the time 1 1 Link to post Share on other sites More sharing options...
