Re: Tapping noise from 3.5 \Rover V8

Surely if the rocker is able to push the valve down, then the guide must be far enough down to allow you to compress the spring and remove the collets? Or are you saying the guide is seized to the valve and is going up and down with the valve? If that's the case, then I think you'll have to grind th...

Re: What gearbox can I fit, 2 wheel drive

The ZF4HP22 is a long box though, even in it's shortest form.
The only factory bellhousing for the V8 is the Range Rover one, and it's very long by itself!

Re: What gearbox can I fit, 2 wheel drive

I'm guessing here, but I would think the 4 speed manual box from a Rover P6 would be the shortest. Then you are getting on to the LT77 and later boxes which are longer because they are 5 speed. I used an R380 + very short bellhousing from Ashcroft Transmission (which is meant for a 4 cylinder engine...

Re: Convert a Rover 4.6 Gems engine to SD1

You also need a spacer to go on the end of the crankshaft as the nose is longer. And a camshaft that will drive your distributor and oil pump as the GEMS engine will not have the features required for that. I'm not sure, but the ancillary fixing holes in the heads may have slightly different threads...

Re: 1970 S2a Land Pig engine debacle

The shortest front end is the one from a P38 Range Rover, but you lose the distributor!

It's what I've done in my Landie.

Re: 1970 S2a Land Pig engine debacle

That is a car type front cover I think. If you were able to get a Range Rover one, it lifts the water pump up considerably which might be useful in a Landie.
The whole front end ancillaries change though, so you should get another complete engine to make sure you've got it all!!

Re: Valve tip height

I had exactly the same problem. I compromised with the average, but it always rattled a bit.
The only real way is to take the heads back off and return it to the machine shop and ask for it to be done properly!

Re: Difference

Indeed that is also true. But as far as the engine is concerned, it can accept either a car 'box or a 4x4 'box. Yes the bellhousings and input shafts are longer on the 4x4 version. And the 4x4 clutch is bigger than the car clutch. So if you treat the flywheel and clutch as part of the gearbox, then ...

Re: Difference

Many thanks, will the range rover gearbox fit the sd1 v8 No, the input shaft on the Range Rover is too long. That's not right. All the engines will fit all the gearboxes provided you have the flywheel & clutch to match the gearboxes. The automatic engines may not have the right spigot bush in the e...

Re: Alternator question.

It does sound like it's not charging.

Is there a signal on the W (tacho) terminal on the alternator? That terminal is connected to one of the three phases and is an AC signal.
