Next newbie stupid question?

Question 1: Is it possible to fit a vacuum guage to a diesel (2.25) Land Rover engine and 2: if yes, where on the intake manifold will I position the vacuum take off?

[Blknight.aus]

possable but pointless..

they only make a vacuum if you have the vacuum generator on the intake manifold if you have that then anywhere on the engine side of the generator OR the main line to the brake booster would give you the same reading.

Wow, you guys must be gentle with us on the dark continent! My LR is a '68 2.25 diesel and as far as I can see, there is no vacuum assist on the brake booster. Was a vacuum generator ever fitted to these engines? Can one be fitted?

[BigJon]

If you have a brake booster you must have vacuum assist. That is what a brake booster is!

[Blknight.aus]

you can fit it and its a simple enough process... its literally held in place by some locating screws and an oring seal on the air intake manifold.

I was going to turn the one that came on my diesel into an exhaust brake. all youd need then is the MC/booster combo out of any petrol series that has the same brake configuration that your running.

word of caution...

you know how slow it is now?

if you fit the factory vacuum generator prepare to redefine slow.

if you still want one if no one else has one for you to grab I wont be to hard to convince that the thing I have wont make a really good exhaust brake and that I should sell it.

Dave, thanks for the heads up. Seems I'll let the vacuum guage go. As to speed: I'm only fetching the beast come month end but some of my mates already suggest that I use a calender instead of a watch and that I trade my GPS and get a compass - the batteries go flat before you reach your destination!

This car will be my hunting, fishing and general bug out vehicle, so speed is not that important. In any case, if I'm in a hurry, I'll take the Honda.

AFAIK, only the Series 3 LWB diesel had the vacuum accumulator factory fitted - Dave may be able to verify this

I had to make a flapper valve to get mine working for rego

It hardly worked! (but passed rego) ... it would be better if the usual alternator mounted vacuum pump or some other vacuum pump could be installed..,

On the S3 6 cyl petrol skeleton that I bought, (see 'Advice needed, lots of it'), a servo assisted brake master cylinder is fitted. The Haynes service manual S2&3 diesel, mentions the servo unit as fitted to the 2.25 diesel engine. Can the servo unit from the S3 6 cyl petrol be used as a retrofit to the 2.25 diesel engine and what is the part number of the fitting to the induction manifold that I need to complete the installation. Blknight.au mentions that fitting a vacuum gage will slow down the performance of the engine. Will the servo unit do the same? If so, what is the alternator vacuum pump that 87Country refers to and from what vehicle can this thing be scrounged?

[clean32]

as an idea

How about an electric vacume pump Like from an MR2 hook it up though a relay from the brake lights?

[gunsports]

Ok, but what is an MR2?
