Buying a car with a timing belt

But just about any part of the engine needs replacement after a certain time/milage?
Why not use a chain that does not age by time and lasts something like 300.000km?
Also is it at least a non interference engine?

>rubber in oil
shiggity diggity

The pistons have divots for the valves so guess Ford was thinking ahead.

Its supposedly made out of or with some kind of "plastic."

>divots for the valves
That is actualy more common on interference engines than on non interference engines.

chains stretch over time

Its Nitrogen based butadiene rubber. Polar rubbers don't dissolve in nonpolar oils

I'd rather deal with this...

Indeed, but unless you are VAG, you can manage that with a chain tensioner.
Ok, the engine will loose some power over time due to valve timing beeing a little off, but at least it doesn´t destroy itself when the belt rips apart.

what am I looking at here?

Than with this

VAG even uses chains anymore? pretty surprising for such an anti consumer company

Looks like a DOHC V-configuration engine with timing belts on one camshaft on each side and gears/chains conecting to the other camshaft.

Your average B5 S4 timing belt change, people didn't like having to take the front off the car every 50k so they switched to "lifetime" chains and put them at the back of the engine for the next generation of S4, see Sadly the plastic chain guides were prone to cracking which forces you to rip out the entire engine to rebuild the timing components every 100k

so don't buy volkswagen? I though this was pretty common sense

>plastic chain guides
i hope the person that designed this was executed

No, but they have other issues now:
>polluting diesels
>carbon deposits on intake valves on direct injection gas engines

These carbon deposits start to affect the engine significantly at about 50.000 km, to remove them you need to remove the cylinder head and clean it manualy.
Somehow people still say the RX-8 was bad...

>Somehow people still say the RX-8 was bad...
the rx8 you had to do it way more often

>the rx8 you had to do it way more often
No, the RX-8 cleaned its ports when operated close to full power.
The VAG GDI engines have that issue even when you commute at 200 km/h.

>buying a car with a valvetrain

We already had that here:

>internal combustion engines
Lmao, enjoy your unnecessarily complex, loud, planet-killing, slow shitboxes

vag? probably promoted
likely now head of the electric division

so a 500 dollar bokudine popular belt

>No, the RX-8 cleaned its ports when operated close to full power.
hardly, the huge issue with the rx8 was always carbon build up, high revving would help prolong it but it would never fully stop it. Either way every time you went to replace apex seals or did a rebuild you'd get them cleaned anyway its completely moot

at least you got a free ipad with your power wheels

>35 seconds 0-100

a pity you will never know love

>issue with the rx8 was always carbon build up
Just drive for 15-30 minutes at top speed once in a while and the ports are pretty much free.

The main issue with the RX-8 was a lack of oil jets on the earlier Renesis engines, after Mazda added an extra oil injector the problem was mostly solved.

However idiots granny shifting and not double clutching like they should still kill a few with carbon buildup.

I love tesla, but the batteries aren't exactly environmentally friendly either.
When I can afford one, or when they make them affordable, I will get one.

tfw put 20v blacktop in my ae86

At least its really easy to change, i replace t belts on these and 3uz all the time, doesnt take more than an hour or 2

>buying a car that doesn’t have pushrods.

Is that a mini timing belt running the oil pump? That seems like a terrible idea.

>twin dizzy
Which engine is that?

>my RX4 13B BP
