Very nice synopsis Simon. Thankyou. It certainly makes sense.
I hope also that this thread will be taken in the spirit of shared knowledge in which I am sure it was intended.
Well done, you finally pointed at the root cause.
Hope nobody gets offended, and all see it’s in the spirit of a better K.
Well I think I followed this, but what i can’t understand is that Scholar prepared engines direct to Lotus for the Motorsport series (I’m not saying that they did any of the things detailed above to the engiines for Lotus); but you would have thought that the handling requirements for a completely different spec of metal would have been known and shared?
Why would Rover develop an engine in such a high spec alloy purely for their mundane cars? They never developed it to produce any great power or torque so I wonder why they bothered?
I meant their cars were mundane (25, 45 etc) not the engine.

68 BHP/litre sounds pretty mundane to me.

More power makes faster on the straights, less weight makes faster everywhere - CC
Hmmmm can’t argue with that I guess. But a lot of people are willing to trade a little extra weight (% wise) for a lot of extra power.

but would be better off with much more power, even less weight, a silky smooth and unstressed engine.
Yeah, but in the meantime I’ll have the extra power thanks.

So now we know the cause (or why my HG has F) what are the best things to do about it. what is the best gasket to use where on the head is it best to do a hardness test where if need be can I get a new head if mine is soft ( I have a 1.4 K16 from a 1990 metro gti, is the head the same ?) any help with this would be greatly appreciated so I can get it fixed and never have to bother again.
Alas Its a 1990 engine I have lying about, what are the differences ? would it take much/is it possible to modify it ?( I am a toolmaker to trade so I have a CNC machine shop to play with) plus is there anything worth doing when the head is off. Also where is a good place to hardness test it I dont want to leave a dimple on an important part nor do I want to test it on a part that doesn’t matter.
excellent interesting info Simon
ta much
