Shit, that's a pretty good deal.

I didn't realize they made 4x4 911s

997.2 is the one to get.  That's when you get direct injection and no more IMS issues.  The base 997.2 almost makes the same power as the 997.1 Carrera S.

Coilovers!

What years are the 997.2 cars?

[Payman]

Mere words cannot begin to describe the awesome.

Lol, that's beyond awesome.

2009 is when they started.  It's the mid cycle refresh of the 997.

lol good point.

But my van weighs 2 tons too, so that one is kinda moot. This would handle better. I hope.

Maintenance on a 13 year old Audi.  I can't imagine the cost...

Was that designed by H.R. Giger?

Seriously, I've read that's a nightmare of an engine when things break.

The S4 and A6 Allroad had this chain engine, while the other cars with the 4.2 at the time had a belt driven set up.  The chain version was designed because it fits in a shorter engine bay.

But yeah they could have done better.

All DOHC vee motors are nightmares when things break. At least what Audi did here is use only three chains whereas some motors (like Ford's modular/Coyote) use four. But in this day and age it's pretty easy to design and build a DOHC vee motor such that pretty much nothing (mechanical) breaks over its designed service life.

[Payman]

The 5.0 Coyote has 2 main chains and 2 connecting ones. Much simpler and robust design.

[Cookie Monster]

I can't even tell WTF is going on with those Audi chains.

[Soup DeVille]

I count four.

It's not the number that would worry me, but the extra wear from constantly going in curves much bigger than what a normal tensioner would require.

3?  You sure about that?

[RomanChariot]

3?  You sure about that?

There appears to be 3 chains that are handling the timing from the crankshaft to the camshafts. I can't tell what the 4th chain is for. I wonder if it is for some sort of dry sump lubrication system?

[Soup DeVille]

Yeah, not quite sure what the front chain there is. It doesn't look like it drives the cams anyways, so technically three would be right.

I take that back - looks like the Audi does have four chains.

The Ford doesn't look simpler to me. In fact having those two "main" chains without active tensioning looks a bit sketchy.

Remember, this version of the Audi 4.2 had the chains on the rear of the motor, so you're seeing stuff that has to be there such as sensors, water ports, starter motor.

Starter motor drive (which is on the lower left).

[Soup DeVille]

Starter motor drive (which is on the lower left).

According to Audi literature, it's the variable timing chain, which runs off the oil pump.
Also, this is the rear of the engine, and the parts alone cost something on the order of 3 grand.

[RomanChariot]

Also, this engine has to be removed from the car to be able to do work on any of the timing equipment.

C'mon man, you think the Ford guys are idiots? It not only looks way simpler, it IS way simpler. I'm sure they also engineered in chain tensioning.

I don't see or hear of many Coyotes having timing chain problems.
