    Cannot rotate engine, hard lock / clunk at 80% rotation on crank.

    I think it's fairly normal practice to fill the engine the first time with the rocker cover off, pouring the oil all over the cams and letting it drain, then fitting the sealing/fitting the cover after. That should help ensure all the top end is well oiled, and if assembly lube (or at least a...

    Prawn and BigAls A3 Track Car

    To be honest I'm not hugely surprised the 10.9 bolts bent. 10.9 bolts are quenched and tempered medium carbon steel, which iirc has a Max service temperature of around 350deg, not enough for a turbo! I think 316 stainless is more like 800 degrees, so hopefully they'll hold out better!

    Thanks for the kind words Nick/others. It was a fun day and really satisfying that we managed to get things done on time and to a standard we were both happy with. Always good to have an excuse to catch up too! Just as a random point Nick, while you're (quite sensibly) completely happy running...

    Anyone have a spare used brake pad with sensor?

    Not sure if it's the same on Audi's but on other cars I've worked on it's worked fine to just link the two terminals of connector together. I can't imagine Audi would have bothered making the system any more complicated.

    Problem after fixing my car

    That's the one! It's been a while since I've done it since to my stint of bad luck with bearings ended a while back. So thanks for jogging my memory!

    Dogbone mount bolt not tightening

    Just as a word of warning, if drilling the snapped bolts out is going well, and you've got it started nice and straight and central, I'd just continue drilling and leave the bolt extractors in their box. You can usually drill it out to the point where near enough only the thread is left then...

    Problem after fixing my car

    Oddly I've had the opposite happen twice. The bearings rumbled when going straight, but actually got quieter when loaded up. It's counter-intuitive, but it's definitely happened to me more than once! One trick I've found quite effective for finding noisy bearings that don't yet have play in...

    That could well explain why nicks now feeling the need to restrict the flow into the inlet to get the idle in check. It might be worth replacing the hockey-puck in that case? Placing the restriction where the system's taking it's air from will place the whole system under the full vacuum...

    Cast arms

    Sorry but I don't think that's quite right. The damping won't be effected by where the ARB is mounted. With both set-ups there is no free movement between the damper and the ARB, if one moves, so does the other, so the effect of the damper can't vary. The effective sprung rate of the roll bar...

    Just caught up with this Nick. If you need a hand with the metal work when the time comes to cut up the bodywork I'm always happy to pop up to see you guys and lend a hand/tools.

    Starting to p**s me off now!!!

    I know Prawn spent a long while looking for a knock, only to find that the lower arm bolts are meant to be one use items, and once you've had the arms off once or twice they needed replacing to get them to tighten properly.

    I'm sure nick could confirm, but I believe the new black finish is still and electroplate rather than paint, so probably isn't any cheaper. I think it's a revision they've made to try and improve the corrosion resistance. Just as a point of interest, it would actually be around 440 as the...

    Prawn and BigAls A3 Track Car

    I'm fairly sure he's got a pair of NA cams in there now, where as the old engine only had one (inlet I think?) It'll be interesting to see it out and about. It was a good weekend, and I've very glad the oil pressure looks like a purely electrical fault! It was very satisfying to see it fire...

    Reading all this with interest as ill be re-plumbing the scirocco's brakes over winter. The servo has to vent it's vacuum somehow after you release the pedal, so won't be a completely sealed unit, and will leak fluid out if it's filled up by a dodgey master cylinder. I think this is usually...

    Engine mount problems

    It should be fine, a properly done helicoil will actually be stronger than the original thread.

    This might crash ASN

    Am I the only person who can't see a similarity beyond them both being a grey hatchback? None of the mods done to the Audi actually mimic the Fiat... Personally I don't mind the Audi, its just an S3 with wide arches and some vents in the bonnet isn't it? I'd be interested to see a comparison of...

    speedo not working, but rev gauge does?!?! pic added

    What car is this? A3 or S3? I don't know for an S3, but on a 5 speed A3 there should be a little plasic part consisting of a square rod with a disc on one end. (S3 may well be the same, I'm not sure.) This drops down into the box before the sensors cap goes on, and it's the bit that spins for...

    Looking forward to seeing this and catching up tomorrow. Even more so now I know it'll be being used as intended.

    The reyland's look like they'll last better for sure, besides anything else, more metal means slower temperature changes and therefore gentler heat cycles in use, which should cause a lot less fatigue and lower peak temperatures. Add that to the lack of stress raisers around the outer edge and...

    Federal RSR, or Nankang NS2R

    One of the MX-5 championships recently changed its control tyre from one to the other (from Federals to Nankangs IIRC). For a season or two they were allowed to run either tyre to keep it fair for people who had the old tyre 'in stock'. They didn't find any real difference in the lap times...
