Mine has a slightly roughness at 3.8-4.2k rpm on a light-medium throttle, at full throttle it isn't noticeable.
I think it is the exhaust, which is Cargraphic silencers which have had a gundo hack. I have checked the heat shields are secure.

Has anyone else had similar?

Could it be an exhaust blow? The manifold-cat bolts will rust away to nothing and stop doing their job at some point. Soapy water in a spray bottle on the joint and a rag over the exhaust exit will give things away pretty quickly. Likewise for the cat/backbox connection.

Remember this one? It's back up on Ebay again.
It's the one which hit a kerb with enough impact to snap a suspension arm.

https://www.ebay.co.uk/itm/274446025437?ul_noapp=t...

It's Cat N, but I notice this has now been added to the description.
"There is a rotational noise from i think a front wheel but not sure of its a bearing."

I wonder if it's the front wheel which took a battering?
Either way, it looks like a £12K Hartech rebuild was only a year ago, so engine wise, it should be spot on.

The invoice date seems a bit odd. The car was unused for 5 years and had no MOT, it then got MOT's 12 days before the Hartech invoice date. So, just guessing, but if it blew up and that's the reason why it was unused for 5 years, how did it get MOT'd almost 2 weeks before the date of the engine rebuild?

I'l going to keep an eye on it though.

It's possible Hartech were tasked with the engine rebuild and getting an MoT for the car. Which would have been best since it hadn't had one for 5 years!

The invoice date would then be the day when the bill was submitted. A flat fee of £10k (probably + VAT), that's page 1of 6 shown. eek

The boot on the MAF wiring on that car doesn't look too clever, like it's got very hot. I see it's done ~7k miles since Hartech rebuild, so conceivable it's happened since. I'd want to check the validity of the Hartech invoice and check with them whether they have seen similar before or it's a symptom of another problem.

I could be the exhaust, though no leaks were noted when I had the PPI 3 weeks ago. There is occasionally an exhaust blowy metallic tick noise at low revs (<1500) on a light throttle, only noticeable when alongside a wall or similar to reflect the sound. I will investigate with soapy spray in the week.
Thanks

Probably one of the heat shields behind the front brake discs. One of mine sounds like someone playing a tambourine when I go round right hand bends. It's doing my fking nut in.

Early factory aero speed yellow manual c2 with a healthy spec and photos of loads of invoices. Healthy premium but you could probably sell the mk2 GT3 wheels and for the correct ones to get a grand or so back.

I just found a great car on Auto Trader.

Love the phone handset, very mid/late nineties. Those wheels would have to come off as would the upwardly mobile badges, and whilst I'm usually a huge fan of amber indicators I'm not sure they work with Speed Yellow.

Shame about the LN Engineering IMSB, but given the cars at 103k you'd probably want to drop the engine for a prophylactic rebuild soon anyway I suppose.

Not a popular opinion but I think ambers on a 996 look st.

On cars from the 80s and earlier they look retro and are usually in keeping with the more angular designs and more basic light units of those periods. On later 90s and 2000s cars with softer curves and more moulded plastics they just look dated.

I don't really like ambers either. With the right colour they look ok at best, on the "wrong" colour (yellow for example) they look awful

Completely agree. My silver '99 car would look daft with orange indicators - everything blends in neatly when it's all roughly the same colour.

Maybe on early 996s in dark colours with 17-inch wheels they look okay but that's about it.

Mind you I might be a bad barometer because I also have lightly smoked indicators and repeaters in place of orange on my ur Quattro, which makes the purists twitch uncontrollably... hehe

We're all different, I think silver cars with clear indicators look dreadful - totally misses the continuation of the shut line from the bonnet/boot that runs through the lights with the different coloured indicator lens.

But that contrast of yellow and amber doesn't work I don't think.

On the right colour ambers can look good, but I generally prefer the clears. I do like them on a dark blue car for example. But on a yellow or red car they clash and don't work imo

I dislike the multiple black sections at the front on the aero car. Is the central one painted black or is there a 3rd rad in there?

I think the standard car has one black section across the full width of the front which flows better on lighter coloured cars.

No third radiator on aero kit Carreras. I believe it's just a black plastic flap that's over that area as part of the black inner same as the standard bumper.

My wheel saga continues, the LM's were meant to be en-route to the UK now, having arrived in Germany toward the end of July.

The update is that the UK supplier believes that the wheels have arrived in Germany, but can't say for sure, and can only say that they "might" be able to get me the wheels, "in a couple of weeks".

I have therefore cancelled my day at Center Gravity, as I may not have any wheels for them to fit - they're now booking for October, so it will (barring a cancellation) be 13 months from order to getting the wheels on the car.

Yes, I've been assured that my wheels, having been made six months or so ago, are unaffected by this.
