1973 Lotus Europa
TC Special 74-3115R
Had some trash that the usual guys wouldn't pick up, so had a brainstorm and packed it in the TCS.
Went to the local dump, chap at the window; "Wow, a Lotus Europa, haven't seen one of those years,
knew a guy who had an Elan". I smiled and explained that I want to get it weighed. "Of course you do, Lane #1".
860 kg in, 830 kg out. Let's see now... 830 kg x 2.2 = 1826 lbs.
Minus me, 160 lbs and minus 50 lbs of tools, fire extinguisher and supplies = 1616 lbs.
That's fuel tanks half full, spare tire in front, rear trunk not installed. Sound about right.
Then went for a short drive in the back country. Sunny day, about time. Lot of rain this fall.
The speedo quit working this week, it was bouncing and chirping before... but it finally quit on Tuesday.
But still made the occassional chirp, however zero mph. Went investigating today and pulled out the speedo.
Yup, the cable is bust... snapped about 18" from the speedo. Guess I have to replace it now.
While I was at it, I compared
the S1 steering wheel to the TCS wheel.
The splines and nuts are the same, but the hubs-flanges are different. Even the columns are not the same.
Think early Spitfire, late Spitfire. TSC on the left, S1 on the right.
Nothing to report. Busy driving.
Replaced camshaft seal and cork gasket.
Also replaced the rubber half moons in the head, at the end of the camshafts.
start driving it again daily and see what happens.
Removed catalytic converter and re-installed the muffler.
Replaced the original steel pulley on the camshaft for the alternator drive, with an aluminum one.
Looks a lot nicer and 1/4 of the weight. Topped up the engine oil, and fired up the twincam.
Yup, still leaks at the camshaft seal. Guess I should buy a new seal. It's not getting better.
Took 3115R to a specialist in Vancouver. Hooked it up to their analyzer,
then changed the needles over to Triumph TR6 ones, B1AF.
Ran too lean, adjusted a bit, got great numbers, and went to Aircare. Passed with honours.
See table below...
the B1AF needles a bit richer. Ordered new B1G ones.
Will make the switch back later when they arrive. Next to remove the cat and replace the muffler.
The cat helped a lot, got up to a working temperature with the B1AF needles, but it's too noisy for me.
Engine backfires sometimes with the TR6 needles. But glad I finally passed.
Get to repeat the facade in 12 months time.
Noticed the weight was wrong on my Aircare slip, so did some research. It's also wrong on my registration.
They have it down at 1650 kg. I told them 1650 lbs. If I do the math, that should be 750 kg.
That means the allowable numbers for the test have changed a bit.
Don't know why a lighter car is allowed to pollute more, but I'm not going to argue with them.
So, now I pass NO and HC in the driving test, but still fail the other requirements. Oh well...
Started to get serious about passing Aircare. British Columbia's emission money grab...
Was looking at Ken's excellent site, http://pw1.netcom.com/~krk/lotus/
He has an article about how installing a cat helped him to pass his emissions test.
Looked interesting, thought I'd try it. What did I have to lose..?
a franchise muffler shop, asked about replacing the muffler with a temporary
They wanted $500 for the job. No thanks. Then went to an auto parts place and bought a generic cat for $100.
Next drove around the corner to a hot rod custom exhaust shop and asked some questions.
Drove home and removed the muffler, not easy, but got it out.
Went back to the custom shop... with no muffler, very loud !!!.
hour and $100 later, drove out. The cat is quite a bit louder that the
muffler, too loud for me...
but this is a test. If I pass, the cat comes off and the muffler goes back on till next year.
At least that was the theory. Did some errands to warm up the engine, then over to Aircare.
---Failed Again--- The numbers are lower than the first time, but not low enough.

I did not
touch the timing, nor the points, nor the Strombergs, aside from raising
the idle to 1100 rpm.
Fuel was part methanol, new oil and filter, new sparkplugs, no air cleaners.
The plugs are the base of the carbs were removed, hoping the holes would lean out the mixture a bit.
|Driving test||May 25||July 3
(cat + needles)
|Hydrocarbons ppm||413 pass||331 pass||19 pass||520|
|Carbon Monoxide %||8.12 fail||8.43 fail||0.00 pass||5.14|
|Nitrogen Oxides ppm||178 pass||0.00 pass||455 pass||5608|
|Idle test||May 25||July 3||July 12||Allowable (corrected)|
|Hydrocarbons ppm||2000 fail||1581 fail||208 pass||698|
|Carbon Monoxide %||9.99 fail||9.37 fail||2.65 pass||5.54|
12... Yes, it really is zero-zero-zero.
NOx, July 3... Yes, it really is zero-zero-zero.
Idle Test, HC + CO, May 25... I think those numbers are the maximums on the scale.
So quite possibly could have been even higher.
but still annoying. Now I have more work and money to spend before test
Been kinda busy past few weeks with work. So not much progress with the emissions problem.
Worked on the oil leak though. Thought I fixed it but no, not yet. Still seeping out through the
oil seal on the camshaft where the pulley is mounted for the alternator. Did more cleaning above and below.
Had an aluminum alternator pulley made up. Looks lot better that the original, and lighter too.
Not much to say, 3115R works.
Took it through Aircare (BC's emission testing), failed with honours.
Now the fun starts. Going to lean it out, new plugs, check timing, clean the air cleaners, change oil + filter.
Filled the tanks with methanol blend. Most likely will buy a catalytic converter to
temporarily replace the muffler. Then try Aircare again. Got five weeks before the renewal is due.
Gave the engine a bath on Saturday morning, and cleaned up the garage.
Decided enough was enough, and replaced the leaking coolant pipe. The grommet
in the frame where the pipe passes through had split, allowing the pipe to rub against the frame.
I cut the old pipe at the rear and pulled it out the front. Cut a new piece of pipe and joined it up.
Eventually will replace both pipes with stainless, not now though, don't want to lift the engine.
Everything seems fine so start driving it again. Weather looks good for a few days.
But 3115R needs a bath above and below.
