Re: Relays

"although they seemed brighter the beam was poor" I think to understand this, you have to separate the bulb from the glass of the headlight unit. As an example, a lighthouse typically these days uses a 250W halogen bulb. The light from this would be scattered 360 degrees from the top of the lighthou...

Re: Adding a brake servo

Hi Ian and David I have been giving some more thought to what happened when the remote servo failed on my Mk1 Mini Cooper - but it was 10 years ago! The remote servo effectively has another master cylinder associated with it - its the bit sticking out from the big cylinder. The diaphragm in the cyli...

Re: Adding a brake servo

Hi David, Fitting a remote servo is quite a popular addition to the braking system, and was offered as a factory option from February 1970. See here for some details: http://www.mgb-stuff.org.uk/braketext.htm#servo. I would recommend fitting a genuine Lockheed one as it is an important part of the b...

Re: My 'New' engine.

Hi Harry, Sorry to hear your continuing bad new! The bearing look to be very worn - more 100,000 hard miles than 500! As you say, this is very likely to be the source of the swarf you have found in the engine, along with some wear from the cam bearings and cam followers. From your comments on the pi...

Re: Replacement Cylinder head

Hi Ian Ah - I now see the point you are making about the valve height. Yes you are absolutely correct that a correction might be needed for the valves, as well as the pushrods. The way to deal with this is to have the seats cut further into the head so the valves sit higher relative to the Rocker Sh...

Ian
If you go back to a document MSWord is likely to have Autosaved it for you. With the forum you have to remember to save if you need to do something else.

Re: Replacement Cylinder head

Try this! The point you are missing is that as the rocker gear is separate to the cylinder head and as it is tightened down on the 4 studs through the pedestals, the push rod will effectively be too long because the distance A+B has reduced. This forces the adjuster end of the rocker arm up and the ...

Re: Forum postings

I have the same problem that Ian has highlighted. If I think I am in danger of losing the text I have enter, I highlight the text and the copy it. If I do lose it I can paste it back in. I do have have the 'Save draft' option but I can never find where it has been saved to - but perhaps this is a se...

Re: Replacement Cylinder head

Hi Ian You are right that in thinking that skimming the head doesn’t change the relationship between the Rocker Shaft, the Rocker Arm and the top of the valve. Also the Rocker Shaft Pedestals don’t change. However I think you are missing an important point! See the attached schematic diagram of the ...
