Don't bother talking to me unless you've done at least another 61 miles.

Oh, and I forgot to mention that the cams are now timed 104/104, so that may also have made a difference to engine running.

Ah, at 104/104 you have to reduce your mileage by dividing 1.025 into it.  So 2.4 miles to go.  Do I have to explain everything?

No, because I already know everything.

Funny, that’s exactly what mine told me, so it must be true.

(104° is the green dot pulley angle spec, isn't it? Has anybody ever made a before & after dyno run?)

I believe there were comparable test done many years ago , not sure of figures . However I found improvements when setting up with 104/104 over 100/110..   You need to remember 100/110 was done for emission reasons for the USA market . To save on costs Lotus did a one fits all policy , this mean't the Esprit was built to meet the tightest  emission laws it would encounter in the markets sold in.    

We did some back to back on an S4, which after fitting verniers with 104/104  cam timing and Alunox exhaust manifold , managed to achieve 300 bhp using oem ECU set up and 1 bar boost  and not much else . 

As Ian said , any cam timing is only an approximation based on where the closest dot alignment at TDC can be achieved .. The moment an engine no longer has the original factory head gasket format , the cam timing goes out .. only slight but not perfect .. The only other way to keep this spot on is to measure your original gasket , get the crushed dimension of your new gasket , and then skim the head for the different thicknesses ..... Assuming the new gasket is thicker, and the timing was cock on before.     When you consider the allowance on the original head skim and gasket replacement was 0.018'', it does not take much working out to realise , with what is available in gaskets , and how many times a head has been skimmed , chances are cam timing will change .. 

When i do a customers engine, i always do a cam timing check before disassembly , In most cases the cam timing is not to spec.. This gives me some idea on machining history before i start ,    I always recommend 104 /104  and verniers on rebuild , as a result  those all get spot on cam timing . They all seem to run smoother , i expect this is to do with timing accuracy and the 104 set up ..  

On emissions , i have not had any issues with 104 set up  on MOT's in the UK ..   

Great job @Chillidoggy , well thought out and executed with precision .,. :coffee:    :thumbup:

I'd expect nothing less from a Watford Exotics franchise :)

Up to 800 miles now. Engine still sounds very nice at idle, and behaves itself at all other times. It’s used no oil whatsoever, and mercifully no leaks from engine, gearbox, or driveshafts. I reckon another 200 miles and I’ll do the oil/filter change.

Now 1,059 miles, that's all the running-in. Oil and filter change today, and we're away. Thorough inspection and I can't find  any leaks from engine, gearbox or driveshafts. The engine is still very nice, smooth, with an addictive power delivery.

TWAT noise is taking some getting used to, might have to buy a baseball cap, a shell-suit, trainers and some fake gold chains to hang round my neck, innit bro.

I'll give that a go, cheers.  I've thrown a fortune at it; still it persists.
