Engine Rebuild & SC Conversion
broken-rocker ..21/03/2008 - Broken rocker arms were the only problem with my engine rebuild.

It was now too late for the March 2008 Slverstone event, MGOT kindly managed to re-sell and credit my entry fee. I had booked the day off work and decided to go anyway and try to get some passenger laps.

I had a very enjoyable day at Silverstone and plenty of passenger laps, most memorable being with Sid Owen in his K series powered MG Midget, the combination of a very experienced track driver and fast car meant we were passing just about everything on the circuit!
Silverstone 2008 with Daisy ..Fast forward to Aug 2008 and my first track day in my B with the rebuilt engine, again its Silverstone but for this evening event we were on the Stowe circuit. My passenger is daughter Daisy.

The car went well all evening, only problem, after a few sessions was some clutch slip.....




Silverstone Aug 2008 .....Whilst having difficulty getting the gearbox and engine to align during fitting I ended up with quite a lot of grease in the brass crank bush. I guess the heat had caused that to get onto the clutch plate.

...I solved this by removing the split pin that dangles out of the bell housing drain hole, drilled it out to about 6mm. Then sprayed loads of clutch & brake cleaner through the hole.

Redgate corner
.....Redgate Corner, the car went well all day, and no reoccurrence of the rocker arm or slipping clutch issues.

One minor problem was one cell of one of the two six volt batteries went down shortly after sign-on. So I needed a push start before each session...
Booster Battery
.....After the trackday I replaced the two six volt standard batteries with one small 12V sealed battery out of my portable battery booster. Later I fitted a second battery of the same type in parallel to provide more capacity.

This set-up works fine and a massive weight saving over the standard batteries.
rev test no engine
.....Back to Feb 08, prior to fitting the engine I brought a rev limiter, then tested it using a pulse generator circuit.
no spd but revs
.....Nearly 7000RPM without an engine!

I fitted the Rev Limiter incase over revving was a factor in the last engine going down.





MGOT-Silverstone-March2009
.....Back to Silverstone in March 2009. Weather not so good with rain and hale. Lots of spinning!

The car ran very well, only problem was a puncture. Brian kindly shot off and got a new tyre fitted at a local garage.

head light cowls I picked these head light cowls up at Race Retro 2009. They actually make a noticeable difference to performance.

The photos on the bonnet were taken of an FIA car at the show to assist with fitting.

new rear UJ I started to notice some vibration at various speeds and tracked it down to a worn UJ - it was a bit of a fiddle to fit but it solved the problem.

Brians P4 also in this Shot.
These two photos were taken by Brian.

In April we also took part in an Open Pit Lane Track Day at Donington.


Mallory Hairpin Mallory Park is a great little circuit, due to its small size it doesn't take long to learn and get into a rhythm.

Again the B ran well all day!






July 2009, Engine Rebuild no2. is for an old 3brg engine that has not run for atleast 40 years! it has lived under my hedge for about 20 years! 3 BRG ENGINE

The interest in getting this old engine going again apart from the "sheer challenge" was to use it as a test bed for initial development work on an SC Conversion for my B & Brians MG Special.

The SC CONVERSION project has been a joint effort between myself and Brian Evans. Lots more info on the SC conversion to follow...

Although the B has ran well on road and track since the DIY engine rebuild, it is time to get some more POWER!

 
3 BRG ENGINE

Not looking too bad... Before storage I put plenty of oil into the bores which seems to have paid as it turns over fine!

This is a +40 Gold Seal engine. At this stage I only intend to do a light rebuild, although there are quite a few bits unique to this early engine that are missing including starter motor and water pump. Finding these will be another challenge!
Beaumanor Hall Classic Car Show Beaumanor Classic Car Show July 2009,
I brought a water pump for the 3brg project here, but when offered up it wasn't correct for this early engine, I shot back to the show and the trader gave me a refund without hesitation.

other shows visited this year in the B inc Race Retro & MG Live at Silverstone.

The Cam on this early engine has additional drive cogs for a mechanical Rev Counter.

Honeing the bores Aug 2009, My MG is still running well with its rebuilt engine.

Here I use a honing tool on the 3 BRG Test Engine.

This is driven by a flexible drive from an electric drill. Plenty of oil was used on the grinding stones.
