Re: King Pin Top Bolt

I had one side of mine that wouldn't shift. The problem is that its not firm enough for a strike from a lump hammer to shift it. No amount of soaking with penetrating oil helped. I ended up taking one of the arms off the damper and with the four retaining screws out I could push the rubber bushes th...

Re: Running on suddenly.

I would have thought a standard B series with a compression ratio of 8.8:1 would be happy on regular unleaded (95 RON) without retarding from factory settings. A lot of engines have been re- bored and had their heads and blocks skimmed so may be over 9:1 now. Certainly mine has, however I still use ...

Re: Running on suddenly.

Well done Mike. My Factory workshop manual only goes up to 1972 which is fine for my car but it means that I have to rely on Paul Hunts Bee & Vee site for data. I found the data in the Haynes manual confusing and I don't have Not_Anumbers engine number. Vic is right in that the 45D distributer c...

Re: Running on suddenly.

The 45D distributor has a radically different advance curve to the 25D and is not recommended by Peter Burgess. The early 18V engines (72-74) had the 25D. One can only presume that the 45D curves are an attempt to reduce emissions and improve economy. The other advantage of the 25D is that it has a ...

Re: Running on suddenly.

Given that your running on problem started when you changed distributors it seem likely that it is timing related. Is your vacuum advance working ? this should help stop running on. From what you say your engine runs on for a long time with the ignition off suggesting you may have a problem with cok...

Re: Insurance

I cant recall Peter Best being a director of the Car Club. He may well have been in the past but he certainly isn't now, he's a vice president. This is a honorary position with now power but I'm sure some influence. I've never been insured with Peter but have friends who are satisfied with their cov...

Re: Insurance

Hello Jon - your quote is very cheap. My car is similar to yours. This year I switched my insurance to Cherished vehicle (part of A-plan) the new insurance partner of the MGCC. I had been with my old insurer (no names no pack drill) for 20 years but every year the fee went up. This year it was £128 ...

Re: Light knocking noise in the engine.

I had a quick look at the camshafts being sold by Rimmer Bros. The shafts were smooth and there was a good radius between the shaft and the lobes. You could also see the evidence of the heat treatment. I'd love to see a photo of a factory camshaft to compare to yours. They were forgings which is goi...

Re: Dragging disc brakes

You could be right Ian, so to be on the safe side the original poster should use brake fluid as a lubricant. I wasn't proposing using engine oil in the hydraulics. Having said that SAE 30 mineral oil is recommended for lever arm dampers. It could be down to the type of rubber as you said. I don't pr...
