Nah it's properly common now the cars are getting older... it will most likely be the bottom accessory pulley or a water pump issue but either way, it needs sorting

I can't do a full and proper setup just yet as the builders are just starting the office and build areas. After that (and when the bank account has recovered) I want to put in a proper flat patch.
I am not discounting the tyre pressures but from what he's said, I honestly think the biggest issue he has at the minute is incorrect ride heights/weight distribution (especially the front/rear biased)
BG Motorsport have serviced the custom BCR's for us before as they're essentially the Ohlin internally. The problem is that the damper inserts (standard track spec that is) are that cheap, you may as well just replace them... another reason why I like them so much.
How long did they leave it running the smoke test for?
I'd start simple and remove/block all breather take-off's as it rules out external accessory items such as brake servos, purge and control valves, etc. Also, keep a tin of brake cleaner or deodorant handy (Lynx works well) and spray it at...
I'm stiffer to but we're still talking suspension, right? Hehehe
We don't know what setup the car is running or the exact configuration either so it could be a combination of anything (too low, incorrect weight distribution, tyres, etc).
A proper geo setup is often overlooked but is also often...
Well you've proven its not electrical and is infact a leak by covering the MAP sensor hole, returning the idle to normal condition.
Have you checked the integrity of the breather, brake vacuum and the rubber hose to the Bi-mode control valve?
Belts aren't expensive on these, we charge £370.00 inclusive of VAT.

The only thing you really need to watch for on these cars is steering and seat fabric condition (try don't wear well), electrics aren't normally an issue but...
Huge thank you to @SharkyUK for helping out today with some of that silly "code" stuff - Normally I'd hit s**t with a big hammer until it works properly but I didn't think Apple Care would class that as a valid repair case.
Tricky to say for sure as i've not been in to Windaz machines since discovering the wonder that is OSX. Get as many cores as you can CPU wise, a good GFX card and as much RAM as you can muster. Solid works doesn't actually require too much to function but obviously, more is better.
I believe what the OP is asking is which position the cams need to be in when the pistons are at TDC as the "notch" is eccentric. In that case, the timing "notches" need to be in the lower position to be done correctly. It can be done in the upper position but you will struggle to get it spot on...
It's an age related failure which some say is due to infrequent oil changes where others say it's due to sitting in traffic... all we know is, you're better off changing them at the time of changing your timing belt rather than not.

Dephaser is simple enough to rule out:
Firstly - Do not listen to Jaff... he knows nothing unless it's a diesel train
Secondly - run the car until it is up to correct "normal" temp
Thirdly - Confirm the noise is present at idle and then raise the engine speed to 2-2.5kRPM - If the noise...
The above figures are pretty decent targets to start with though and not far off where I set them prior to corner weighting.
Don't forget though that the car axles *shouldn't* be set level unless you've got the driver and some fuel in the car to (CW%). Don't forget that tyre pressure will have...
As above, a well maintained 172 Cup with some choice mods is really all anyone needs to have fun in.
I've considered ATB's, cams & remaps for mine but all it really needed was some good brakes and to make sure all the bushes/mounts are nice and tight. Not the fastest thing on the planet but I...
So you've also got the rear end lower than the front... These cars like a bit of rake (or face down, ass up as we say). This won't be helping your situation either
Step 1 - What is the red LED on the clockset doing when you turn the key: On/Flashing 1Hz, On/Flashing 4Hz, On/Solid & stays on, On/Solid then goes out?
