Brake Light Switch - Sorry Lucas

Sorry Mr. Lucas, but after we were black-flagged and lost 2 hours during last years Charlotte Motor Speedway race because the MGB brake light switch was crappy, we've replaced you with a higher quality switch from a Datsun 240Z, part number GO300, from eBay for $7.50.

I noticed the pedal arm has some play side-to-side, so I installed the switch at a slight angle; turns out it would not have made a difference but there you go; it's just the price of being gormless.

Here it is installed, with the brake pedal NOT engaged :

Here with the brake pedal partially pushed in:

Here it is installed on the Brake Pedal Box. More Tea, Vicor?

Windshield wipers... well maybe not


Removed the plexiglass windshield (eg scratch collector) that we had so much trouble with (eg couldn't see through) in the rain at Charlotte Motor Speedway last year (eg Black Flagged for passing under Yellow that we couldn't see).

Drilled out the rivets and removed the remaining screws (eg 25% of the screws have been lost to vibration over time). While it was out I stripped down any surface rust (eg it's English) and coated them with De-Ruster treatment.

You can see the red Kill Switch that I will be moving to the center of the dash (as per ChumpCar Rules [.pdf]) while the windshield is still out.


The big item that was planned to do while the windshield was out: adding some Windshield Wipers! I had scavenged a system from Crazy Rays last fall and had been waiting impatiently to install them.

Finally get to it and.... can't be done as is.

The roll bar, eg the excessively over-engineered roll bar, is in the way. The photo to the left is a shot from inside the car looking forward. The farthest blue bar is completely unnecessary for LeMons, ChumpCar, and probably VRG, SCCA, NASA, and pretty much anything else except a Sherman Tank Demolition Derby. Never-the-less, I can't bring myself to remove the extra pieces; after all I've hoodwinked talked my friends & family into racing this beastie and therefore the more safety qualified the car is the better. Who cares if it doubles the weight of the car?

Sigh.

So, options at this point seem to be:
  1. Cut out extra roll bar bits (don't wanna!)
  2. Install some other after market wipers, possibly a single one on driver side only
  3. Install the MGB wipers, but from above the windshield! Top rollbar may be in the way :-(
  4. Drive without wipers; since we now have a GLASS windshield we can use Rain-X and it may be ok. :-(
  5. Do a 1968 American Rambler wiper system eg twine and clothes hangers manually operated
  6. Rig up a few hairdryers on the hood pointed at the windshield (this is LeMons after all)
  7. Hire a Baltimore street corner window wash guy to sit on hood during race
  8. <Your suggestion here; please leave comment below.>

We are racing the MGB GT this year in GOLD (the traditional 50th Anniversary color)... and I've re-registered all the races will will be in so as to have car "50" for the whole year... all the races except ChumpCar Nelson Ledges October race... there is still time for that team to drop out and we can grab the number.

Magic = Not Natural

I searched Amazon.com for "MGB RACE" and the first set of results yielded this bit of opinion:



I mean OH COME ON! It must be possible for the love of ^&%^%$%$#%$!!!!!!!!!

sigh

IT LIVES!!!!!

  • New head gasket installed, water was flooding cylinder #3
  • Adjusted valves, 2 were way off
  • Of the 2 center rockers that needed shims, one was missing and the other was folded over so twice the thickness it should have been
  • Rocket cover vent was clogged
 More pics later, but for now the bottom line is:


First drive after rebuild: no oil covering windshield, fender, hood or roof!

Mystery Bolt - Can you identify?


While replacing the head gasket in the engine (1973) of the MGB, I had the rockers sitting on a piece of cardboard while I worked on scraping the carbon off the head, cleaning, and measuring for warp.

The next morning I start work again and notice this plug/bolt laying in the area very near the rocker assembly. I CANNOT find a location that this would go, either in the rocker assembly or the cylinder head... or the carb (webar DGV) for that matter. I poured through the MG Service manuals, and the Moss catalog as well.

Stats: 
  • it is about 0.6 inches square (about the size of the Spark Plug at the threads!)
  • the threads seem worn down
  • it was mostly coated in nice clean oil
  • it is not brass
  • hex socket is for 5/16ths allen wrench
  • It's not an air-injector hole plug
  • It's not a rocker/valve gap adjustment bolt
Leave a comment if you have any clues to this mystery!!

Is it possible the last owner/mechanic dropped it into the engine at some point and it's been rolling around - that may account for the worn threads - maybe??

Video: Where the Elite Meet to Cheat 2011

Here is a cool video pvreditor made of the Charlotte 2011 race; our beloved Goldbrick may be seen being towed off the track at the 4:58 minute mark:

Race Report: Where the Elite Meet to Cheat 2011

Where the Elite Meet to Cheat at Charlotte Motor Speedway was a riot as expected. Plenty of this report snipped & edited from Driver Dave's email.

We finished the race with a blown head gasket; 53th place out of 66 entries; we were in the pits the last 4 hours with the engine ripped apart. A noble effort!

 

Rain. And more Rain. And no windshield wipers. And no RainX (plastic windshield).
Friday: set up day: Judge Phil comes over with a friend and says something like “this is my friend Randy, he’s a pretty good driver and your car really caught his eye… any way he could sneak a few laps in it sometime?” … Carl is in a great mood and of course said “hell yeah”… good karma and all that. Also - it's always a good idea to do the penalty-wielding judges a favor.

Tech Inspection: should move under-hood fuel filter closer to pressure regulator so it is more protected and doesn't flop around; brake light switch may need adjustment (woops - more on that later).

Paddock all set up Goldbrick style: XBOX, fridge, leather couch, snacks. We'll unload the car sometime... oh wait did anyone remember to actually bring the car?!?!?!

Saturday, Race day one: we finished the first hour as the top class C car.  Carl was driving in the rain and doing a great job.  Until he passed under yellow - scratchy plastic crap windshield with no wipers was almost ok until it stopped raining and muddy water coated it.... oops. Penalty: driver change *whew* Second hour we had a terrible driver transition and refueling.  Dropped 30 laps back of top C car.

Then Ray got the best black flag in the history or racing.  He gets stuffed by some other car on a corner and ends up hitting some cones (mandatory black flag here.)  His penalty was to sit out for an hour... OR...  Let Randy Pobst drive our car during the penalty. Randy is a professional car roadracer.  Check out his info on Wikipedia.  So, during that hour Randy posted 60 laps, one of the top 10 fastest laps on the track (1:21), got us back to within 5 laps of the lead!  He was doing stuff we didn’t know the MG could do.  UNREAL! It's written up here:
http://www.thetruthaboutcars.com/2011/09/randy-pobst-lemons-mgb-gt-handles-well-bad-brakes-low-on-power/


I had forgotten to replace my lucky stick-shift knob with a "real" one... sorry Randy!




Randy dropped the rear tire pressure to 2 or 3 psi below the fronts, so now Front 29psi, Rear 27 psi; also said the rear drivers side would "clunk" on the one hard left, and that we really should adjust the pedal travel.
 

Then the problems started....  While Kurt was driving, he got flagged for brake lights.  Took us 2 HOURS to fix the stupid brake light switch on the MG.  So, we were well behind.  Dave made up some of it and was having a GREAT hour.  Posted a 1:24 lap and was trying to emulate Randy.  Was gaining 1 lap every 4 laps against the 2nd place C car and 1 lap every 5 against the 1st place C car.  Then Dave says he turned into a moron and ran out of gas while on the track...  Lost everything he’d gained waiting for the tow truck.  "I’m advocating a gas gauge Carl..." We added 7.5 gallons... so that is our new volume (thanks for measuring that Dave!)
Max went out... into the heavy rain... zero visibility.

We finished day one pretty well though.  160 laps even with none of Kurt’s last 20 laps in the rain registering - several transponders were not working in the heavy rain towards the end of day one.  We were only 30 laps out of 2nd C class car.We were 47th place, "good enough" with all that lost time.


I guess 43 is old enough to smoke, so what the hell was I supposed to say?
Sunday, Race day two started well.  Ray was putting in some good laps.  Posted a 1:28 lap time!  Then 1/2 hour in the car started overheating.  When we looking it over, discovered water in the oil... unfortunately AFTER we refilled the radiator.  We’ve driven it without water before, so sent it back out!






Exhibit 1: A major disadvantage of having a light colored paint job

Kurt was driving when he was black flagged for the oil pooring out of it... :( 

We cleaned it up (drained everything; replaced oil filter plus oil change) and let it idle for a good 15 minutes; revved it a few times. We were thinking of sending it back out with new oil and no water.  

Judge Phil drove up and so no f@(#)%^ing way. Probably a good call.

 
So, we had no choice but to try to replace the head gasket.  Judge Phil assured us it was an easy job... Then disappeared...  We had some generic too-thick cork for other gaskets and decided to go for it. With four hours left we tried.  Couldn’t get it done by the time they called the race 1/2 hour early with lightning.
