That makes good sense. For sure on mine, the cork gasket is clearly flush. When the chaps did the rebuild I bet they didnt leave it 1/4" proud. So, I will reassemble with a bead of silicone instant gasket on the faces of the cork gaskets and especially the joints at the ends, then use instant gasket on the sump side of the rubber gasket and grease on tother side. Will keep my fingers crossed !!

I dont have a breather on the top of my rocker cover. There is a plug for it on the air filter housing, but nothing on the cover. Should it have one ? The engine pressure on start up is about 80 psi, then after it warms up it goes down to about 50psi or so.

All A series engines will benefit from having the rocker cover breather system piped into the carb. 803 / 948 & 1098 had them as standard, the 1275 had it deleted by BMC but it is advisable to retro fit. It will not effect the oil pressure at all.....

I put it all back together again yesterday afternoon and used some silicon instant gasket sealant smeared along all gasket faces. I was 100% I had sorted the problem. Then I waited several hours and cranked her up. All seemed fine as Daisy ticked away for a little while. Then I decided late in the evening to take her out for a spin to the petrol station to fill up the tank ( I know.....Daisy is not registered for the Hong Kong roads yet, so off I went with the still valid British Tax DIsc in the window and the original UK plates ).

First problem was when I got to the petrol station.....the 20mm hole reducer I fitted in the fuel filler tube ( a stupid Hong Kong regulation....to meet current standards must be less than 23.6mm ). The pump nozel would not fit ( arghhhhhhh ). Quite embarassing really :oops: So I had to fill up the jerry can and then fill the tank via the jerry can filler nozel which did fit.

When I checked this morning, there was a drip from the back of the sump and now a drip from the front too.....how annoying.

Im wondering if it would have made matters worse using the instant gasket sealant on the rubber main gaskets ? Possibly pushing the sump lower and making the cork gaskets at the front and back sit further away ?

Im thinking of taking the sump off again, this time remove the curved cork gaskets and pump a bead of sealant in the gap where the cork gasket is seated, squeeze it in a bit and allow to harden. The refit the sump this time only using some grease to coat the rubber gaskets ?? Cant get hold of curved rubber type gaskets quickly....need to get the car through the MOT next Thursday, so do need a quick fix. I can then order some more quitable gaskets and refit at my leisure when they finally arrive in Hong Kong. Where can I get these better rubber type gaskets rather than the cork type ?

Alternatively, for the MOT, I could take off and reseal the sump, wiping the sump dry. Then only run the engine during the MOT, so oil dripping would be very unlikely in such a short time.

I did have to drive the car up some steep hills back home last night, and it was very slow going up Garden Road ( down to 2nd gear ) pinking quite a bit too I think.... so today I have adjusted the mixture a little making it a little richer and have very slightly adjusted the timing. Seems to idle smoother now...

Tomorrow morning we have a movement licence to take Daisy out for the day so will know if these carb adjustments have worked properly.

As for the sump oil leak....I think I will try resealing again, but any quick fix advice to this would be appreciated. :)

Charles,
Moss sell them and it is definitely the way to go.

The drip from the back of the engine plate will not be helped by your lack of rocker breather.

You need to make some system for the crankcase to breath into the carb or air filter.
No amount of gasket will make an engine airtight.

For the time being, (my favourite being) A few tampons rammed between the sump and back plate should get it though the test.
Just write MOWOG on them :) .

Daisy hits the streets of Hong Kong

Post by swithland »

We all set out at 7am to meet up with other club members at the Hong Kong Yacht Club carpark in Causeway Bay. On the way down ( after 1/3 mile ), Daisy started to judder a bit. I thought it strange and was a little concerned but carried on thinking she just needed a good run to clear out all the ticking over of the past few months.

Then we all went in convoy through the harbour tunnel and headed off to Shatin to meet the rest of the members at the University. The juddering progressively got worse and at one point I was having real trouble to keep her going. Then all of a sudden everything was fine and we made it to Shatin.

There were about 30 club cars there ( mostly a lot of fancy expensive cars ), but also a Triumph Herald, Riley Sprite a nice looking Jag E type and many others. No other Moggies....

The club members were busy taking photos of Daisy and having a good chat....

We then all headed of to Sheung Shui ( the boarder with Mainland China ) where the Hong Kong Jockey Club has a very nice Country Club....the idea was to go in convoy and arrive in convoy and then have a nice brunch.

A few minutes after leaving Shatin, the stuttering came back with a vengance, to the point I had to stop in a layby. All the club members passed by except a Chinese chap, his wife and son with the Triumph Herald. He's a mechanic by trade and wanted to help out.

So we had a good look. He thought it was mechanical, but I thought it was electrical. He pointed out the connector on the top of the oil filter housing was dripping a little oil, so I pulled out the tool box and tightened it up......which stopped the leak.....then checked the oil level which was fine.

Convinced it was an electrical fault, I checked all the wires leading through the screw type terminals, the HT leads, etc which all seemed fine. Then I took off the dizzy cap and there was a little black marking on the rotor. I then inspected the points which had clearly been sparking as they were full of crud. I cleaned them, checked the gap but the engine was still just as bad.

I keep a new spare set of points and a condenser in my tool box, so replaced the condenser, then cleaned the points and reset them with a piece of card !! Bingo......Daisy fired up and was a sweet as a nut.....

The chap with the Herald told me to follow him through a short cut to Sheung Shui and we arrived at the Country Club 5 minutes before the rest....much to their shock who thought by now I would have been on the way home on the back of a tow truck !!

Brunch was excellent.....superb sausages, eggs, baked beans and all the trimmings.....all for about 7 quid a head ( 4 quid for Matthew ).

Afterwards, we headed off to Mong Kok to the Police Safety display. Going through the heart of Mong Kok drew a lot of attention.....which was so much fun. Whilst we were going down the back streets, a line of Harley Davidson's arrived who were also invited to the event.

In total, 20 classic cars and about 20 Harley Davidson's.

We didnt win the most popular car prize.....that went to a tiny little BMW one seater with the door on the front ( a bit like a bubble car or a mecherscmitt ).

So leaving at 3pm, we decided to take full advantage of the days movement licence, and took the easter harbour tunnel over to Hong Kong Island, and cruised along the eastern corridor down to Wanchai. We drove through Wanchai, up through the wet fish markets, and over to Queen's Road East heading for Stanley on the South Side of the Island. We drove over to Stanley but when we got there I heard a strange noise from the front of the engine....so stopped somewhere quiet and had a look. The four bolts holding the fan and pulley in place had come loose and were rattling.....I could not understand how the hell that could have happened, but tightened them up anyway and off we continued.

We headed back down to Wanchai, then into Central Hong Kong, driving through Lan Kwai Fong on the way ( that was fun......a lot of people thought it amazing ).....and then drove back home to Western Mid Levels.

All in all, we did about 100 miles today. Two incidents which should not have happened. The condenser and points were brand new and should not have failed......and how the bolts came loose on the fan blades I will never know, but I will take the bolts out during the week and put in some new locking washers and a blob of silicon too, just to make sure.

Matthew ( our son....aged 9 ) was busy with the video camera, so I will see what footage he came up with and make a youtube vid later this evening.....will post the link.

2 things........

(1) Im glad I keep a full oolbox in the boot.
(2) Im glad I keep a spare set of points and condenser in the boot.

Will change the points and condenser to electronic ignition after Christmas....Im not having that nightmare happen again.

i had exactly the same symptoms when my condenser packed up. i was reading through and before you had cured it i had worked out what it was :D

glad you got it fixed on the road. when mine went i thought it was the headgasket and ended up getting towed (200 miles) home! Free recovery ftw!

you're lucky you got to your rattly bolts before they parted company. that could have been messy!

Firstly it was great to hear about your trip - especially as you had to fight so much red tape to get there!
As you've got pics, it could make an excellent article for the club mag... ;-)
The condenser and points were brand new and should not have failed......and how the bolts came loose on the fan blades I will never know, but I will take the bolts out during the week and put in some new locking washers and a blob of silicon too, just to make sure.


Secondly - welcome to the modern world of classic motoring - fitting new parts can increase your chances of breaking down :( Carrying the working old parts is a good idea.
Thirdly - the fanbelt bolts should have spring washers. Without spring washers and with a lot of engine judder it's not a massive surprise that they shook loose.

Despite having a full tool kit in the car and plenty of spares, im going to join the Hong Kong AA just to be sure......Im really glad I didnt get stuck in the Cross Harbour Tunnel......that would have caused total chaos !! Very annoyed about the condenser....that really should not have happened.....and because im normally very dissorganised I felt thankful that I had kept a spare condenser in the tool box !!

Yes, the fan bolts issue could have been very messy. I suppose it must have been caused by the engine vibration when it kept misfiring. I suppose the blades would have gone straight through the radiator if they had completely come out. Definitely going to sort that issue out on Monday night.

Hi Ray, yes I should forward some of the pics and the story to the MMOC. Could be an interesting story. Still cant get over that condenser. Im amazed her indoors was so calm. I was feeling well stressed at the time. Im currently uploading the video onto youtube, so will place the link in about an hour !

Crankcase breathing

Post by swithland »

Im very confused on crankcase breathing.

My 1098 engine was fully reconditioned 200 miles go. The carb has no inlet for a breather pipe and neither does the rocker cover on top. The only breather I can see is on the side of the engine which connects to the tappet cover plate and heads down to the bottom side of the outside of the engine.

There is a connector on the outside of the air filter housing.

The cap on the rocker cover is the plastic type which seems to allow for some movement of air in and out.

I have ordered some MOSS rubber type sump gaskets ( to replace the front and rear existing cork ones ), but if crankcase pressure is an issue causing the tiny oil leaks, then how can I overcome it if there is no connection on the carb for a breather pipe ?

I can buy another rocker cover with a breather type connector off ebay, but would I then connect up to the air filter housing ?

Ive read in other posts that there should be a metal rocker cover cap for this arrangement, is that absolutely necessary ?

Im quite confused about all of this.....but do want to solve the problem once and for all...

Charles,
If you don't want to loose time and buy a new rocker cover, just braze a 90° bend of copper pipe into the existing cover. You can then run a pipe from this to the air filter housing. The disadvantage of this is that it clogs up the paper element in the air filter. Another way is to tap the inlet manifold and fit a stud and run the pipe to there leaving the air filter housing as it is. If you decide to tap the manifold, remove it first and clean off any swarf before replacing.

Declan

Declan, Ive got a stud on the inlet manifold that the rubber pipe to the brakes servo goes into. Could I put a "T"piece on that servo rubber pipe and connect to that ?

Ive been recommended to drill a hole in the rocker cover and screw a male type airhose connector in....that would take care of the rocker cover part. I suppose if its ok to put a T into the servo pipe then I could use an airhose T Connector. That would make the whole job very easy.

Then.....if ( big if ) that is all OK, would I need to change the plastic type vent cap I have on the rocker to a metal sealing type ?

Charles,
I have the servo connected to the inlet manifold and the rocker cover to the air filter. It's different filter and I have no problem with it clogging and no oil leaks.

You will need to restrict it to about an eighth on an inch or there will be way too much suction.

Personally I would look on ebay for the correct rocker cover - it will make life so much easier and maintain the negative crank case pressure you need to prevent leaks.....

Agreed but I think he needs a quick cure due to an MOT deadline.

In the short term it shouldn't be a problem, just be aware that it needs restricting for long term use.

Re: HELP HELP REGISTERED ENGINEER NEEDED FAST

Post by swithland »

Ive had a busy afternoon. Firstly I took the sump off and resealed it. Then I took off the rocker cover and fitted a brass air hose connector through the side. Could not fit it through the top because of catching parts inside the rocker cover. Took a while trying to explain what bits I wanted in the Chinese hardware shops !!

Then connected the brass connector to the air filter housing. I know it would be better to connect after the filter, but I need a quick solution so this is how it will be.

Ive not started up the engine yet, as I want to be sure the sealant has properly gone off, so will wait until tomorrow.

Ive double checked all the brake pipes for leakage and they are fine ( wow some good news ), but have noticed a small oil weap from where the backplates connect to the rear axle bodies, so ive had the rear brakes to bits, taken the backplates off and resealed them with sealant. I wont know if thats cured it until Daisy is taken for a good spin, but in any case that wont be until after its MOT on Thursday.

Ive also noticed a small drip from where the speedo cable connects to the gearbox. Ive tried hand tightening up the connection but its as tight as it will go. Ive not used any pliers to force tighten the connection. Does anyone have an idea how to cure that leak ?

And, there is a tiny drip from both the gearbox and rear axle oil empty plugs although they are both very tight. Does anyone know how to solve that too ? Would that be to use PTFE tape on the plugs and then screw them in ?
