  1. Are we talking about Racing Green Lotus'? Here's the most recent one of it being clean, at Caffeine & Machine. 8,300 miles in five months means it's rarely clean!

  3. No. The none return valve in the oil filter does that , which it is why you must have the correct spec filter.. When tuning these 900 series engines many years ago it was discovered that the oil supply to the cams was excessive , flooding the cam housings with oil that would could be better distributed at the bottom end and turbo. By fitting a restrictor you can modify your oil flow to the cams and engine as a whole . By doing this you can better maintain oil pressure , increasing it in a well built unit. However anyone who is not sure of what they are doing or does not fully understand the concept should avoid doing it until they are confident it is correct for their build.. To be fair the benefits far out way the avoidance which is why most of us tuning professionals do it as a matter of course. The drain back is a completely different side of the oil flow dynamic. I am so sorry Fabian, i was trying to do a play on your words, but it obviously came across to strong.. Sorry.. I thought you had forgot the pics because you had posted so many more since, i was just checking as we are all so interested , a picture is worth a thousand words . On the cam followers , i agree longer skirts have advantages in certain situations. BUT..... not just any long skirt follower . The ones GK sells will do the job perfect as they are a tuning part.... However did you know the crown on the GK ones is a lot thicker so the follower sits higher on the valve, providing the required skirt clearances... Now why you need to know this is because everything changed has an effect .. So, to explain. With most engine rebuilds, especially when fitting new guides , you will re-cut the valve seat. this in turn will reduce the thickness of your shims when fitting the cams by .010 - .030 depending on a lot of factors. When resetting/ matching the combustion chamber volumes further cutting back of valves is normally used as the primary method before fine fettling. ( but not many bother with the chamber matching) . On top of that you then fit a cam follower which is circa .020 thicker . When you take into account the original shim thicknesses vary from .080 to .100 , you can have a situation where the shims you will be fitting can be getting a tad on the thin size. You want to try and keep them north of .070 to be on safe side. I only say this as you mentioned this engine had been professionally re built before , so i expect they will have been re-cut prior and again when you did it . As a result , especially as you are now fitting new guides another cut will be needed , this will compound the situation unless you intend to fit new valve seats at the same time .. This is just something you may not have known or fully understood , i hope i have put this across in a way that is not condescending .... This is not the first time we have bumped heads. So if you wish me to stop posting observations just say, i will not be offended.. This post is already to long to go into the pump side of the flow dynamic , but i am sure someone will give a technical explanation .. etc.. If it was easy everyone would do it. .. keep going..

  4. 5 years on, we're now at 329 FFM's out of 18,815 members, so 1.75%. Out of those, over 50 are free FFM's to our armed forces/blue light members but to be fair, we do have 25 paid up Gold members now. If you'd like to support TLF, please do sign up. It's not cheap running a website that has 10,000 odd people visit it each day and your contributions are very much appreciated.

  6. Following 14 months of misery, after having to surrender my driving licence due to a medical condition, the postman finally delivered it back today It should have been here 2 months ago if it was not for delaying tactics by the DVLA who claim that they have a massive backlog. Escalating a complaint and writing to my MP finally secured a result!

  8. Hi Dave(changes) , sone people might get upset by some of your comments - not sure if you intend for them to come across as they do? I'm too old a bunny to be concerned. I havnt got around to doing the cam pics because Im busy taking the engine out and its low priority. My garagevis small and they are on the other side of all my parts. I read about the restrictor mod on the Lotusbits website aboutv7 years ago! As you said to me about the cam followers, why change the spec? Incidently, Gary Kemp sells those followers and told me they will work with a standard 107 camshaft. They have advantages over the shorter skirt in my opinion. The oil pump is pretty simple. The problem on here is no one has bothered to post any significant detail about it. All I found was its difficult to build pressure, but no explanation of how it works. Hopefully that will change as I go into it in much greater detail then ever before, with figures! Im very pleased all the the sealing is perfect on the engine. Now I just need to rip it apart and see whats happened. Should not take too long. I have already done the difficult parts the first time around, second time piece of cake. Everything is so much easier with practice. Im learning a lot and will have this up and running towards the end of March. Guess what if it isnt perfect I'll rebuild it again, if only to make a point and set an example for other enthusiasts.

  10. Well I have been thinking rather than messing around measuring valves and guides etc I am going to renew the whole lot. New valves inlet and exhaust and new guides. I am going to get the head completely redone. I am also going to replace all of the bottom end bearings. Its a very small cost in the scheme of this build, which has gone way beyond what you might expect. Its actually frightening considering I have done all the work. Its essentially a new car and the engine has to be just as good. The next time this engine is run it will be better than before! I am tempted to get new cam shafts rather than use used ones. I will fully investigate the oil pump and system. I have a spare auxillery housing Andy gave me which i can use to determine how it works. I will have the engine out today or tomorrow. By end of March latest it will be running again and fully rebuilt. Not sure if I want to fit an oil restrictor, especially when my problem seems to be lack of oil. Ill think about it.

  13. You'd be very unlucky to need the liner clamps. The liner sealant will have set rock solid, and unless a piston is stuck solidly in the bore and you then hammer said piston out, you'd not disturb the liners.

  20. This design of brake ducting doesnt have to have the feed pipes sitting in direct airflow. The brake disc is effectively a un-housed fan impeller. By adding the backing disc you've now "housed" the impeller which will create a suction. You only have to feed the ends of th{ piping somewhere near a fresh air feed and it will draw it's own supply in, you don't need to force it in.

  24. Fabian, If I suggest any course of action it is in the best spirit of support and collaboration, and I'm confident that is true for Dave as well. Your enthusiasm is unsurpassed, inspiring to those of us plowing uphill on deep restorations. Garry Kemp is highly regarded, seems a valuable source for guidance as well as the components he distributes. No doubting your experience with absent oil pressure by any here, just cautionary words on what to take away from all this. The cam journals offer a considerable bearing area for their workload, the tappet/lobe interfaces are splash oiled as are the tappet/bore surfaces. If they have been wet they have been lubricated, for the most part. As to the oil pump, convention for checking condition is tip clearance between rotor and annulus (spelling?) and the side clearance between those and the housing in which they operate. Straightforward enough for checking, not a common point found to show wear in engines as they are lightly loaded and always operate in a lubricated state. FWIW. Press on mate.

  27. Dropped the radiator off at Serck Motorsport this morning ready for it be re-cored and have a new frame and fans fitted. They're also going to pressure test my condensor/chargecooler assembly to see what condition that is in before I decide what route I'm going to take with that. Was interesting talking to Darren while I was there. They have three separate workshops down there, one dealing with traditional copper/brash radiators etc, another dealing with the ally side of things and the third for inspection and cleaning, F1 teams being a big customer for that. That department is busy at this time of the year in the run up to the new season. Sounds like my radiator will be in good hands 😀 Should see it back in a couple of weeks; I've got plenty else to do in the meantime...

  29. aha - i am happy somebody else has finally raised this problem as i have it too. Never felt in on the NA or the S i had but it is REALLY noticable in the 400 but only when its VERY WET. about half a second to a full second delay for sure. I though i was going mad - had silverstone check the brakes twice but found nothing wrong; Had the brake fluid changed as a precaution and for my own sanity (and the front pads as they were 70% worn) and it still does it.... looks like they all do that then..

  32. Effect to geometry is determined by the plane in which relocation is performed. Outward re-positioning of the lower arm outer pivot will change the camber and its curve, kingpin inclination ( therefore steering offset, where the axis of steering meets pavement relative to tyre contact patch ) and bump-steer curve. An adjustment of toe obviously required as well. It's not something to pursue without some analysis, my back-yard engineer's thoughts offered free of charge.🙂

  33. No, Its quite qualified, we have been doing it for years , The standard oil feed gallery is 7mm in which we insert a grub screw drilled through to suit individual engine spec , most common is 3.2 - 3.5 mm .. my own high spec engine is fitted with 2.5 mm restrictor. see pic It was covered in the 412 BHP...THAT WILL DO NICELY...... posted half way down page 11 from April 16 2015 onwards

  36. I’m getting stitched up, here. I’m not surprised, my sick record is way better than Sparky’s, which is no doubt down to years of debauchery and alcohol abuse. God knows what he’ll be like when he gets to my age, you can’t do cam belts by remote control from a hospital bed.

  41. The flight experience was quite something. You were pretty much guaranteed to be sitting a few feet from the super-rich and famous, yet the crew went out of their way to make it special even for the once-in-a-lifetime travellers. On my 1999 flight (before cockpit doors were secured) I was invited to the flight deck during supersonic cruise, which was really special. Whilst chatting to the flight crew, as we were approaching land, the reheats were switched off - air resistance at Mach 2 is quite something and you really did get thrown forward. On returning to my seat, I found my crystal glass of rum hadn't survived the transition and had flown off the front of my tray. On each flight, all passengers received a gift. These were always high-quality items, and there was a huge variety of them. I have dozens, as the remaining inventory was sold to staff at ridiculous rates. I'll post pics as I locate the items. Sterling silver key ring by Links of London. Smythson 2003 leather-bound diary. Sterling silver luggage tag - some tarnishing but best to leave it that way! And a variety of baggage tags.

  42. THAT whisky. 206 numbered bottles produced in 2003 from a cask laid down in 1976. I believe 199 made it to Catering; I suspect I know who acquired at least 1 of the missing bottles. In Summer of 2003, each Concorde flight carried only one of these - it could only be purchased inflight. At £200 a bottle uptake was limited, and I managed to get four, three of which I bought myself onboard. This is the last one in my possession; I sold the others to collectors in the UK, Belgium and Japan. Currently one of these is for sale in the UK for £4000. Might taste awful, I don't know! I only wish I'd kept another bottle and opened it. Eventually I'll sell this one...

  44. Hi, I’ve just bought a mint 2015 Evora S sports racer manual in motorsport green. I’ve come through Peugeot 106 & 306 rallye, S2000 (crashed 😢), then kids, Megange R26, MX5 mk2, FPace, Panda 4x4, M135i before the Lotus. Some are still in the garage. This Evora brings all the passion and fun back to car ownership I’ve missed since the 306 & S2000 days. It was expensive compared to what else is available for the money, but it is bloody amazing to drive, stunning to look at (I love the green, bright but not too shouty) and really rare. Plus the kids fit in the back! My only niggle is creaky door cards (if anyone has some advice on this?) otherwise it feels genuinely very well built. I think it’s a keeper. I’d be interested in the cars history if anyone knows.
