I’ve also been throwing my wallet at my car again, £7 and a bottle of Radweld later and the Mito is no longer suffering from incontinence issues. Just need to MOT it now.

Can you split the chain, Attach the new one and use the old one to pull the new one through?

#no idea what I'm talking about.

That’s exactly how we do our engines at work.

Dave!

Surely if you can get to a chain to see if it's worn/change the tooth it's on you can change it for a new one?

You can get to the cam sprockets just by taking the cam covers off. The rest is rather harder to get to. Here's a pic of someone else's:

I'm guessing that's after about a day of pulling the front of the car apart - or just flat out removing the engine?

[Sundayjumper]

Yeah. Pinched from this thread if anyone wants to know more :

How did you manage to move the chain one tooth on one of the cam sprockets?

The sprockets aren’t actually keyed to the camshaft, you just loosen the bolt on the end and they’re free to turn. Like a vernier pulley in effect. There’s apparently a special funky diamond-coated washer in the middle that keeps them together once torqued up.

So with the crank locked to TDC you loosen the bolt, rotate the cam to the right position (the special tool will make sure it stays there) and tighten it up again. It’s really pretty simple.

Picture of my tool in action:

Most modern cars are like that now, you use a locking kit to time the crank and cams, slip the belt on, loosen the cam pulley, set the tension, tighten the cam pulley, job done.

I guess the idea is it that all the slack is automatically pulled to the tensioner instead of locking the pulleys where you could end up the a tooth’s worth of slack on the front belt run which would only show up when the engine was turned over.

Been quite a few issues on the current ( now old ) m3/4 with the unkeyed crank pulley slipping and putting the timing out, sometimes just needing a reset, other times needing a complete engine replacement.

And even more progress ! The decent weather this weekend has really perked me up.

Good news - it turns out the Cayenne has the OEM switchable sports exhaust

Bad news - one of the valves is seized

Good news (?) - it's seized in the loud position

I'd noticed the "Sport" button on the centre console of course, but assumed it was just a gearbox / damper setting. It clearly wasn't making much difference to the exhaust as it's seized open on the driver's side. I've disconnected the other side so that it's noisy in a balanced way now. I do like a V8 burble.

And having driven it a couple of times today, adjusting the timing has made a huge difference. Smoother idling, smoother take-off, and has more low end torque. I'd always thought it was a bit gutless low down but wasn't sure if I was just comparing it unfairly to the Touareg, which of course had "quite a lot" of torque. The Cayenne is still way short of that but it feels like it's closer to where it should be now. The MOT conveniently runs out on the 15th so I've got it booked in on Friday. I won't be surprised if they turn their noses up at the suspension as the front lower wishbones are definitely past their best but we shall see. Fingers crossed.

[V8Granite]

The drive is always taken up by the clamping force, the keyway is just there for location. Items normally have to be religiously clean though or a new bolt fitted the the crank, bottom pulley etc if it’s a stretch bolt.

Good news on the timing work, still very strange how it became out of tolerance though.

Dave!

[Coaster1]

Quite a list GG

This!

Can't make my mind up about the FF, need to see it in the fresh. Can't argue about the V12 though!

The red is gorgeous.

I expect it is vacuum operated? If so then more likely not seized but rather you have a leak on the line.

Particularly if it’s in the open setting as they start open then shut when the vacuum suction builds up so not likely to seize open as they shut every time you start the car until you press the loud button.

When you say disconnected the other side - how’d you mean?

You can get both pre-06 with lower tax rates though? I bought Ste's old 3.2 TT and it wasn't in the 500 bracket.

But on the whole it's a pain. Lots of interesting old cars with big engines but it's a big chunk of change just to keep them on the road.

[V8Granite]

The difference is doing an extra 900 miles a year or not, it’s tiny if you use the car. For a weekend car doing a small mileage it’s noticeable but otherwise not.

Indeed but ones I find are slightly newer attracting the higher RFL. Just not worth it now, which I suppose is the overall objective to get them off the road

Its only an extra £300 a year, stop finding excuses and just buy an interesting car before it's too late.

Vacuum operated, and trust me, it is seized. I've been under there to check. I can't tell if it's the actuator or the butterfly that's seized though. Maybe both.

When you say disconnected the other side - how’d you mean?

Pulled the hose off the actuator and stuck a short M5 bolt into the hose to seal it !


They seize in the open position - IMO - because that's how they sit when the car is cold and damp and stationary. Unless you drive a heck of a lot, the car spends far more time like that than it does with the valve closed.

I don't think the overall objective was to get them off the road when the tax was introduced - that was 2006 and they were new at the time
