Subject: [Mgs] MGB clutch slave bleeding issues
Message-ID: <6C815610-C1D8-4AE0-9117-E94F7951C2AF@epbfi.com>

I?m pretty sure this gets into FAQ territory, but I?m at the end of my tether here. 

The car is my 1974 MGB. I?m attempting to replace the clutch hydraulics. Bought the $60 some-odd kit from Moss, which is seeming like a mistake. Got the master mounted and fastened to the pedal and all that. 
The slave has some kind of label with it saying that the inlet hole and bleed screw may be reversed. I might can see why, but the hose included in the kit is only long enough to go into what may be the wrong place, putting the bleed screw in a place where it?s less effective. 
What can I do? The holiday?s ticking away and I really need to be able to get the car into the garage under its own power. I live alone and don?t have anyone who can help. Please tell me something I can use because I?m seriously about to lose it here. 
Thank you,
-William

	When slave is mounted, the bleed screw should be in upper hole; hose in lower. If hose is short, it won?t quite fit and will probably kink if forced to.  If hose is put into upper hole, bleeding will be nearly impossible. 
	If Moss supplied a short hose, can you re-install the one you just removed? It would seem they would owe you the correct hose, a quart of fluid, and free shipping.  
	Desperate times can require desperate measures. It?s not unknown for MGB owners to disconnect the coil wire and to drive into garage on the starter.

The hose must go in the end port of the 
slave.  The bleed nipple must go in the side 
port, which does come out from the highest point inside tke cylinder.

We just picked up a 75 MGB with this Rover engine.



Our next step is to thoroughly clean the bottom and try to discover the source of an oil leak



I know MG engines have "the usual places" for oil leaks.   Is that the same for Rover engines?  This is a whole new area for me.



We think it is a Range Rover/Discovery efi auto 9.35:1 from 1988 onwards according to this:  https://rimmerbros.com/c/Rover-V8-Engine-Numbers



It is hooked up to a Muncie 4 speed and has a carburetor sitting on top so its not fuel injection.

Dave,

You might want to visit these MG Experience forums, do a search on Rover V8
and ask questions. There is a wealth of information on these forums:

https://www.mgexp.com/forum/mg-engine-swaps-forum.40/

https://www.mgexp.com/forum/mg-performance-forum.83/

>From my experience with my Triumph TR8 with that same engine, they leak a
lot less than the MGB 1.8.

As said the Rover V8 shouldn't be oily as is common with the 
4-cylinder.? So it's really annoying that having had a 'clean' engine 
rebuilt with a new front cover it soon developed a drip from where the 
sump, block and front cover join on the left.

I am using premium exclusively in my '66 B. It has a Gold Seal motor in 18GB spec with approx. 95K miles, and a fresh head (<10K miles). ?Premium? around here is 91 octane with 10% ethanol, so it still pings occasionally on hills. I?m running a newly reconditioned points distributor, and trying to dial in the optimal timing.

Later models with low compression engines might very well run on regular.

	If your engine number has L as its last digit, and you are certain that the engine has not been modified, 87 octane is fine.
	If your engine number has H as its last digit, 89 octane is a safer choice.  
	With ignition max advance at 32 BTDC and in good tune, if engine knocks/pinks when you are climbing a hill at 2500 rpm, try a higher-octane blend.  
	My engine, 9.5/1 compression, likes 89.

These engines cost a lot to rebuild.  Regular is probably too low.  I just run premium to make sure they get enough octane, and don't burn enough that it?s a serious financial issue.

I have two Lucas Altette horns that need repair. There is a chap in Walpole, Massachusetts who supposedly does this work, but he has not replied to my voicemails and emails. Does anybody know of a repair service for this type of horn?

As already said if you have a low compression engine then lower octane 
should be fine.? If high compression then you will get the benefit of 
better performance and economy with higher octane.? Low ethanol is 
better in both cases.

Because the fuel today is so different to when these cars were first 
produced the original timing specs are no longer relevant. If you get 
pinking then back off the timing until you don't at any combination of 
throttle opening, revs and load.? With high compression and high octane 
try advancing bit by bit until you get pinking, then back off a bit till 
you don't.

You are less likely to get pinking on low compression even with low 
octane fuel, so if you can run the book figures for timing without 
pinking then do so.? You might get a bit better by advancing, but you 
can advance so far that it stalls the starter but still doesn't pink.? 
That's obviously too far.

Good point. I just did not want to waste money if not needed. My bad g

It is not for the octane grade only, that premium fuel is the best choice. 
It is best to avoid ethanol additions as much as possible. 
In the Netherlands we still can choose between 5% or 10% ethanol. 
Premium fuel 5% is the best and offers the least chance of damaging the old type of fuel lines - hoses and gaskets in the carburettors. 
It also offers 98% octane, which had the least chance of pings.
The final advantage of 5% ethanol is, that this fuel has a higher energy content, which gives a better mpg figure. 
So it is worth while to make the best choice. 
I even use 5% ethanol premium fuel in my daily driver Mazda 6, which gives a nice fuel economy and a clean fuel system.

As already said if you have a low compression engine then lower octane should be fine.  If high compression then you will get the benefit of better performance and economy with higher octane.  Low ethanol is better in both cases.

Because the fuel today is so different to when these cars were first produced the original timing specs are no longer relevant. If you get pinking then back off the timing until you don't at any combination of throttle opening, revs and load.  With high compression and high octane try advancing bit by bit until you get pinking, then back off a bit till you don't.

You are less likely to get pinking on low compression even with low octane fuel, so if you can run the book figures for timing without pinking then do so.  You might get a bit better by advancing, but you can advance so far that it stalls the starter but still doesn't pink. That's obviously too far.

Here in Washington, a small gas station which buys gas from an independentrefiner is allowed to sell alcohol-free gas, but it's heavily taxed, like 50 cents agallon more than ethanol-adulterated fuel.? (And we already have the highestgas taxes in the US.)? I'm lucky that there is a grocery store 1/4 mile from herethat sells alcohol-free premium, and another store a mile away that sells alcohol-free regular.? Since I've started using alcohol-free regular gas in my lawn mover Ino longer have to have the carburetor rebuilt every spring.

I think most of the concern about ethanol is misplaced, or at least exaggerated.

One, who still has 50-year-old rubber parts in their engine? These expendable components have all been replaced multiple times at this point, and all the replacement hoses have been ethanol-compatible for a decade at least.

Two, all California fuel has contained ethanol for a long time. That?s a test involving 40 million vehicles, and probably one million vintage and antique vehicles, including my stable of 2 or 3. I have never noticed any bad effects from fuels containing up to 10% ethanol.

It seems to me that the people who are always warning about the ?dangers? of ethanol are the same people who never use it; that is, that have no personal experience.

The biggest concern about ethanol is that it absorbs water over time and degrades.  See this article:  https://www.goldeagle.com/tips-tools/what-are-the-effects-of-ethanol-in-gasoline-and-how-to-protect-your-engines-against-it/

Also, it may or may not be an improvement from an environmental standpoint given the energy, land requirements, fertilizer, etc, required to plant, grow, harvest, and process the corn.

You might get a bit better by advancing, but you can advance so far that it stalls the starter but still doesn't pink. That's obviously too far.

    A few points to mention here from Han's post -
    The octane rating in North America is calculated
      differently than Europe where the North American values are
      typically about 6 points lower. so Han's 98 is around 92 here in
      the USA. Depending on local petrol stations, I use 91 or 92
      premium. Octane requirements vary due to elevation so in higher
      elevation (mountainous) regions of the USA, premium is typically
      89.
    
    
    Ethanol is a lower btu value fuel so mpg will be
      less. Ethanol has about 30% less energy. During my high mileage
      driving days using gasohol, I saw about a 1 mpg reduction, a little more than
      what the math would indicate.
    
    
    A response to Max -
    I agree about ethanol. I have been using E10 in my
      cars almost exclusively for the last two decades. I did have a
      premature failure of the gas hose between the SU carbs in my 67BGT
      about 15 years ago that was likely caused by the gas formulation.
      More recently, I replaced the fuel sender in my 64B and the
      plastic float absorbed fuel within a few weeks, also likely due to
      ethanol. However, Moss sells the original style brass float as a
      replacement. Those have been my only issues. New rubber components
      are likely to be ethanol resistant.
    
    
    
    The main issue with E10 is that it absorbs moisture
      and in time can undergo phase separation where water can
      accumulate in the fuel tank. However, that involves being in a
      humid climate and significant time to allow the alcohol to absorb
      the moisture to its saturation point and then having the alcohol
      evaporate, leaving behind the water. If you drive your car
      frequently and routinely gas up or do not live in a coastal or
      lake area, there should be no problems with gasohol.
    
    
    There is a premium cost for straight premium gas -
      in Idaho it is about 30 cents a gallon more expensive and can be
      hard to find. But I have found it readily available in boating
      communities.
    
    
    Another point -
    Gasoline does not absorb water as readily as gasohol. If you live
      in very cold climates where condensation is
      common, water can and will settle in your tank. When I lived in
      the extremely cold climate of Montana in the 80s when gasohol was
      not available, I experienced gas line freeze ups. We had to keep
      our tanks full to avoid humid air and had to add gas-line antifreeze ("Heet" aka methanol, 12 oz per tank) to avoid this. With
      gasohol, that is no longer an issue.

Ethanol makes big Agra happy= more political donations.
My back g Healey was built in 1976. Have replaced my hoses and rebuilt my
carbs twice.
I just had all fuel hoses replaced and top of carbs rebuilt before refiring
the engine on my 67B
I give my Healey low lead Aviation gas every so often, but try to run
ethanol free high test. Will do the same with the B .

I don't drive either one enough to burn the valve seats.
Happy motoring.
Our driver  season is nearing its end. I hope the B will extend it with
roll up windows.

The problem with hoses isn't ethanol but the rubbish rubber that they 
are made from these days.? I've had replacement hoses fail while what 
were almost certainly original were still on the car and sound.? 
Eventually I removed those and checked them and they were completely 
crack free even when slit lengthwise and opened out. I've had replaced 
carb hoses crack under the braiding, which is impossible to see until 
they actually start leaking, I won't use braided anywhere now.

The usual scare-mongering claim with water in ethanol is that it rots 
tanks so you should brim them over winter.? But that doesn't 'hold 
water' either because ethanol fuels can absorb far more water than 
non-ethanol fuels so there is less liquid water in contact with the tank 
in any case because there is no more water vapour getting into tanks 
containing ethanol fuels than there always was with non-ethanol.? 
Absorbed water vapour has no effect on anything in the system other than 
a slight reduction in performance.? If it wasn't being absorbed and 
going though the system causing no harm it would lie in the bottom, 
build up, and eventually be sucked into the system when it reaches the 
filter at the bottom of the tank.? Liquid water in fuel has a far 
greater propensity to damage the engine than absorbed water vapour.

Avoiding ethanol where possible, and using lower dosages, is purely 
about the possible long-term damage that MAY happen in our cars.? 
Vintage and veteran cars used materials in their fuel systems that are 
more vulnerable so it is more applicable to them anyway.

The thing I do agree with is that it is scaremongering and being seized 
on by companies to sell you stuff you don't need.? We went though all 
this before with unleaded.
