    Lagonda Rapiers

    Bernie, Thanks for the book note - bought one of them! I recall another case of fun with SU pumps - we had one fail in the aforesaid Rover while away from home . Father finished up removing the cap over the points, sitting on the driver side mudguard operating the pump with a screwdriver, hanging on with his left hand through the drivers window......Eventually SU fitted a diode across the points to reduce the burning, and they lasted a lot longer then. Rover went to some length to reduce the failure to proceed cases in the P5 3-litre model, specifying a double ended pump - one pumping chamber, with operating bodies on both sides. jp 26 Rover 9

    Lagonda Rapiers

    Bernie, Can I assume that the extra pump underneath is not original? When I saw the high mounted SU pump on the Rapier it reminded me of a 47 Rover we had that used to suffer from vapour lock in summer , due partly to that high mounted sucking pump! And the ability to return excess fuel to the tank - surely thats not original? Rover implemented a reserve fuel electrically, via a solenoid at the tank, which closed off the normal supply pipe, and opened the pipe going right to the bottom. jp 26 Rover 9

    Trickle charge battery with cables on?

    I have a battery in the back, under the spare wheel, so access is poor. I ran a fused lead from the battery poles to a 4x4 type weatherproof socket under the rear licence plate, for my trickle charger. If I open the battery isolator to work on the car's electrics, the charger stays connected, but the car is safe to work on. jp 26 Rover 9

    Why does my 1929 Cadillac ride so poorly?

    Continental Steel call the 'grease is bad for 5160 steel' idea as BS, or in their words, neither they or their supplier have ever heard of it. Many spring steels are quenched in oil. jp 26 Rover 9

    1960 MGA Restoration

    Last time I worked on a twin carb car (Rover 2000TC, 2 x 2" SU HD8), part of the final set up involved setting the clearance of the connection from the rear carb (directly connected to the throttle linkage) and the front carb - some is needed to ensure the front one returned to its idle stop. The specified clearance was given as being able to just run a roll your own cigarette paper through the gap. jp 26 Rover 9

    1960 MGA Restoration

    Try checking out this site for how the mechanical advance works... This part rotates the make/break cam forwards, while the vacuum advance moves the whole plate that the points are mounted on. Some cars also run a vacuum retard , as in my Porsche 928. You did find the screw under the rotor button that retains the advance stuff on the main shaft? I once had a mini that had been little used for a while and one day would not go much faster than walking pace - the mechanical advance plate was frozen onto the main shaft. If you know the Lucas part no for the car you can lookup the advance curve it should produce. Most such distributors do a simple straight line advance which is finished by ~3500rpm, maybe up to 30-35Deg. jp 26 Rover 9
  7. Bernie, Talking about the approach to problem solving in the early days of motoring reminds me of the story about , I think Napier, and their first 6 cylinder engine. For some time they struggled with rough running, could not find anything wrong. In the end, the story goes, they lowered the compression on No 5 cylinder, and it ran well. Problem solved. My 26 rover has its dynamo chain driven, but the chain tension is adjusted by having 2 of the 3 mounting stud holes slotted (in the dynamo flange), so it pivots on the 3rd stud. The fact that the 501 is RHD is curious - was there a time in Europe when the driver's side was decided by the makers? If so, when did that change? jp

    ZDDP issues

    In Oz we have a very good source of oils suitable for older vehicles, some with high ZDDP - local company , but they are present in USA. Been here since 1926, so they know a bit. I use a high zinc 10-50 (HPR-10) in an 80s Porsche V8 SOHC, and a couple of 90s Miata engines with no issues. Not sure if they are classed as 'expensive' in US terms. They also do a lot of lubes for 20s and 30s models, as Steering boxes, single weight engine oils etc. Very helpful people. As I understand ZDDP levels, its most important when a newly rebuilt engine is being broken in, but less so with a well used engine. jp 26 Rover 9
  9. Are there any rules about importing Asbestos into USA ? Down here in Oz now Customs (now Border Farce) go nuts when anything that MIGHT contain asbestos is imported, and reserve the right to dismantle (at importer's cost) in a search for traces - gaskets, clutches, brake linings etc. Not every car is checked, but enough to make it a real worry.

  10. I got new 2910/AB6 18mm plugs here for a very good price. jp 26 Rover 9

    button-head grease nipples

    Ken, I know its a bit late, but still... I believe you have TAT type nipples - these are on my 1926 Rover 9 (along with a few ordinary nipples). You can get the relevant gun fitting from . To fit this to a US gun, use a 1/8BSP male -> 1/8 NPT female adaptor, which shouldnt be hard to find - Pegasus Auto? john P 26 Rover 9

    1967-76 P6 manual gearbox engine. The engine number didnt move to the side between 3-5 for a few years after acquisiton. This block doesnt have the pad for the side number. See jp 26 Rover 9

    Grease / Oil for Steering Box

    Re "particularly the Rover P3 which specifies oil for the front suspension" - the P3 suspension was all rubber bushed, except the kingpins, which had a thrust ball bearing, seals , and a reservoir for a mix of heavy oil and grease. The bushes did not have a long life - too small for the loads. jp 26 Rover 9

    Borg Warner DG250 Locking up

    With any auto trans that has stood for any length of time I recommend a thorough fluid change, including the converter and cooler, and change filter if fitted. This can do wonders for every aspect of the box. My 35 year old 3 speed MB box (Porsche 928) has only one vice - if left for more than a couple of weeks, its slow to take up in reverse; there are couple of leaks of 1 drop a week coming off the cooling hose fittings. jp 26 Rover 9
