thats knackered.

Every one ive owned has never used any noticable amount of oil between changes (3000km)

Sounds like worn bores / rings which is why your burning oil off.

Whats it look like shining a toruche down the inlets, can you see any oil leaking around the valve stem seals?

Sounds unliley its using that much oil from stem seals though

There is brown oil sludge on every intake valve and the oil consumption is 1/10th if I just drive around low speed in the city. That doesn't mean the barrels and/or rings aren't bad too.

The brown sludge is likely to be blowback from the oil being pumped into the bores, oil will be fresher looking, again hardeer to explain.

Do a compression test anyway as you said you have the equipment coming.

After the test crack the plugs out adn pour a teaspoon of oil down the plug hole and do another test of each cylinder.

if the compression goes up you have worn rings / bores.

plenty of engines around in Japan, since your close cant you get one shipped over?

Here's the dyno plot. The shop tried to charge me for the A/F plot as a separate run again saying it's a separate chart, why not charge for the torque or the humidity or the temperature separately hehe.

Standard except the full tyga system and 112/115 jets:





It made so much smoke above 10000rpm that the dyno room's ventilation couldn't cope with it. Eventually I'll import an engine from Japan, total cost should be around 500-600 GBP.

Aye, that motor is buggered. I can imagine it is running so rich due to the oil in the system - it is burning it so counts as fuel.

A shame but they all have to die sometime!.

Would not worry about your clutch or even spend anything on this - it is a case of throwing good money after bad.

Rest in pieces little engine.
