If both senders give the same result, are you sure it's the sender and not the gauge? SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

Geof, Maidenhead's not too far from here, I can pop over if you get really stuck. SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

If it's pinking, retard it by a couple of degrees straight away until you figure out what advance curve your distributor is giving. With an old fashioned distributor (i.e. not mapped), timing is a compromise anyway. SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

The alternator bracket bolt is 5/16" UNC by 2 inch long. I think the pulley bolts are only about 15 ft-lb, with a spring washer under the heads. SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

Geof(f), Thanks for all the info, I had almost given up on blatchat, and that wouldn't do at all 😬 You can take the pump off without removing the engine. It took me about an hour and a half, going in from the top. I removed the carbs, steering column and RHS engine mount. You don't have to remove so much if you go in from underneath, but I'm getting too old to go 'round crawling under cars unless I have to. You need a sawn down allen key for one of the bolts, as there isn't enough room for a full length one. SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

I cleaned it all up, screwed it back together and it's no better. Does anyone know where I can get the pump overhauled? SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

IMVAO it's a fairly dumb design. The water pump pulley is usually attached to the water pump flange with four 5/16" UNC bolts, accessible from the front. You have to get the pulley off anyway, even if you remove the water pump. I would strongly recommend replacing the alternator bracket bolt as they are prone to corrosion, and you don't want it breaking in the block. SEP field working, not spotted in 103,300 miles.

I saw a brave soul whizzing between the two lanes of traffic on the A34 on a quad bike. I didn't think quad bikes were road legal but it certainly had a registration plate. SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

I would suggest 6500 max if you are feeling conservative, and up to 6800 if you are feeling brave. SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

I'm fairly sure the oil pressure relief valve has taken to occasionally sticking open, with the rather alarming symptom of no oil pressure at idle 🙆🏻. I took the pump apart, looking for foreign matter or anything else untoward. The only two things I found was firstly a mark on the relief valve plunger, just outside the seting area. It looks as if it was made by a fairly coarse file. The second mark is a polished crescent, presumably caused by the plunger rubbing against a turn of the spring. I've put photos on webshots quickies, but it's not easy to show very much because my camera doesn't have a closeup facility. Are the marks related to my problems, or are they a red herring?

What's the best way on a rover V8 which has hydraulic followers? SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

Hmm. Probably plugs if that's the last thing you changed, but.... A hotter plug is literally hotter so that it doesn't soot up at low throttle. If the problem is at high rpm WOT then you should try a colder plug SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

Some guy built a 212kg hillclimber (featured in an issue of Racecar Engineering), so maybe the question should be how to make that road legal. Wings, Headlights, Handbrake, Indicators SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

I know there aren't many people around who really understand these beasts, but can anyone recommend a specialist? A friend just bought a BMW 2002 witch has this as standard, but a previous owner has changed the camshaft. We're a little stumped as to how we can get the fueling adjusted to suit.

They're all like that Sir. When I came across this little 'gotcha' I was told that the pulleys would have to be machined or shimmed to get them to line up. I gave up at that point, and the kit is still sitting in the shed SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

If you're going to buy new bits I don't think you can do better than Caterham Parts Dept. Uprights are safety critical, and it's not nice when they fail, as I know to my cost. SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

Buy a proper cutter. It will cut the braid cleanly so you don't lacerate your hands on the frayed ends. SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

No chance mate. I don't know what bits you think are worth transfering because the dedion setup is generally considered to be an improvement over the live axle. SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

I think they're built like bridge girders. In my experience the main problem is rust and the fact that the fibreglass cracks around the mounting holes. SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

Grads spec should be dedion, so the ride quality is quite different from a live axle car. I don't know why anyone would suggest 28 psi for a live axle, I use 18 psi. SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan

I don't know anyone who thinks you can get away without a fuel pressure regulator. I would strongly recommend fitting one. SEP field working, not spotted in 103,300 miles. Some photos on webshots, updated 25 Jan
